Here is a more detailed explanation of the exploit.
The Pepaire-Bueno brothers exploited a bug in MEV-boost’s code that allowed them to preview the content of blocks before they were officially delivered to validators, according to the indictment.
The brothers created 16 Ethereum validators and targeted three specific traders who operated MEV bots, the indictment said. They used bait transactions to figure out how those bots traded, lured the bots to one of their validators which was validating a new block and basically tricked these bots into proposing certain transactions. […]
So hardly an attack on any core system of cryptocurrencies.
So they discovered faulty code and made some money?
Can anyone explain to me how this is illegal?
The code is a contract. If someone writes bad code and loses money, then write better code - just like if someone writes a bad legal contract and loses money.
The justice system is awful.
IANAL and all, but bad/unfavorable contracts and literal deception/fraud are two different things, at least in the legal system. Not everything that’s technically possible is also allowed, obviously.
Compare it to using a security flaw to hack into a system. Technically you’re only using the official API, maybe in unusual ways, but still. But you’re doing it in bad faith and causing harm, maybe pretending to be someone you’re not or injecting fake data into the system, and that can make a difference.
Hacking a private corporate system, which is generally on closed nets and requires an internal actor / phishing, is significantly different from exploiting a code fault on a public network.
Trustless systems rely on mathematics to secure their networks. This is both the revolution of them and the risk. If you build a system of value and it is on a public network, and you fail to properly secure it, that is supposed to be the risk. You lose money, hopefully go bankrupt / lose credibility, and a more efficient actor eats your lunch.
Treating it like a traditional system with these unspoken legal safeguards when it uses a public blockchain and public network is absurd.
What’s absurd is this crypto maximalist take.
You can’t just make up your own permission and punishment system, and then expect the legal system to just step aside and let it handle all disputes, especially when it comes to fraud. That’s like founding your own city in an existing country, and declaring all existing law obsolete. I know some people think this is a real possibility, but the real world doesn’t work like that.
This is like saying they discovered how to pick a lock so deserve everything in whats locked by it.
The didn’t pick the lock, they created bunch of fake exchanges.
No.
It is more like finding a gold mine on public BLM land. It is over treacherous mountains only experienced climbers can access. There are no signs or doors saying it is licensed to anyone; indeed, it isn’t officially registered with BLM. So the climbers go in and take as many gold nuggets as they can carry.
Unbeknownst to them, it was a mine discovered by rich and connected people who have cronies in BLM. Rangers go and arrest the climbers and say that you aren’t allowed to climb, climbing is illegal, and taking gold from that mine is illegal because someone else found it and dug it, even though they didn’t properly secure it nor did they put up any signs. They assumed the mountain was enough protection.
This is closer to the situation.
Imagine believing that regular people have any rights whatsoever to “public” land.
You withdraw cash at an ATM but the software has faulty code which causes your balance to remain the same after withdrawing any amount.
You notice this and then empty the entire ATM this way, making $200,000. I’m sure once you explain to the jury that the ATM just gave you a bad contract, they will acquit you.
Frustratingly vague for a Slashdot write-up.
“These brothers allegedly committed a first-of-its-kind manipulation of the Ethereum blockchain by fraudulently gaining access to pending transactions, altering the movement of the electronic currency, and ultimately stealing $25 million in cryptocurrency from their victims,” said Special Agent in Charge Thomas Fattorusso of the IRS Criminal Investigation (IRS-CI) New York Field Office.
Good to know the prosecutors have an understanding of what they’re prosecuting… Not even a single mention of MEV in the DoJ press release.
What’s funny is that that’s a description of MEV.
gaining access to pending transactions, altering the movement of the electronic currency, and ultimately stealing $25 million in cryptocurrency from their victim
I skipped “fraudulent” because neither MEV bots nor this attack can be called fraudulent imo, although MEV is definitely taking value one didn’t help create.
Let them eat MEV bot operators.
Yea, we wouldn’t want anyone doing anything illegal with crypto… 🙄
We also wouldnt want anyone doing anything illegal with dollars, euros, yen, etc. Crypto is money and all money will be used for illegal things
True, but Crypto has been awash with scams from its inception. Blockchain inherently rewards those who engage with it deceptively since access to tokens = ownership, there are no take backsies, 0 consumer protections, and it’s global.
Honestly if I get scammed I don’t have the time nor money to fight it, sounds like mostly protection for those at the top
If you get scammed using FIAT you can just call your bank and they can issue a chargeback through the card provider, especially if it’s credit.
The same things that make it like that make it good money. If i hand you a $100 bill i cant get it back without either asking you or force. With today’s payment methods i can just call the bank crying that i never did that transaction and fuck you over. Deceptive auto renewing memberships like gyms and other things dont work either because crypto like cash is a push payment instead of a pull payment. I cant just take your money whenever i damn well feel like it you have to actively give it to me.
Edit: it also truely makes it “your money”. A government goon can call up your bank any time and have your account frozen or drained because money in the bank is a conditional IOU subject to revocation at any time for any reason with no explaination to you required.
Your solution is to blame people who make mistakes, and reward companies who scam them. Real money is backed by governments and a justice system. The alternative is anarchy, and bitcoins show it really well.
Yeah, we are going to have to agree to disagree there. What you call real money backed by the government and justice systems has always failed eventually. Because people manipulate it for personal gain. I wish you good luck manipulating Bitcoin since it hasn’t happened in the 14 years it’s existed. Lots have tried, all have failed.
Never! Except with early pump-and-dumps, whale manipulation, spoofing, wash trading, Mt. Gox, or what’s happening with Tether.
But besides all that stuff creating massively disruptive volatility on a slow as shit network, what’s not to love?
Exactly, companies and services have scammed users, but the core protocol is as good or better today than it was in 2010 and it has not been hacked. Trust me, many people would be extatic to see it happen. The fundamentals are rock solid.
If I took $100 cash from you under false pretense, it would be a crime and I would be prosecuted for it. I would also have to expose myself by interacting with you. If I trick you with a fake login page and steal all your shit from your crypto wallet, then according to the blockchain that’s just fine, and I can do it completely anonymously from the other side of the planet with 0 hope for anyone to do anything about it. I had access to the tokens, so I can do anything I want with them and no one can stop me, reverse it, or even find me. That’s the issue.
Every crypto bro I’ve talked to has said some version of “well don’t get scammed then”, which is such a fucking stupid and asinine answer. Every financial system has consumer protections except for crypto because they are 100% necessary for normal people to survive.
US Attorney Damian Williams said the scheme was so sophisticated that it “calls the very integrity of the blockchain into question.”
If that’s actually true, they should be given a sentence of time served and a job writing useful software.
It’s not. They tricked some MEV-Boost bots into doing bad trades.
Still highlights a vulnerability doesn’t it? The system is only as secure as the most vulnerable piece.
No, it really doesn’t. That’s like creating a bot that buys and sells company shares automatically, and saying the stock exchange has a vulnerability because your bot makes bad decisions.
More likely they’ll get the Mitnick treatment.
Lesson learned: always use your girlfriend’s browser to look up how to do crime.
You’d think these guys would know how to open a private Firefox tab.
Whoa. A slashdot link? Remember when that wasn’t a cesspool, but it’s been awhile. For an ars technica summary this was extremely disappointing with regards to details.
My only take away here is that we really should make H.E.B (highly educated brothers) a part of the vernacular.
I’m honestly very surprised that site is still around. Like digg.
Sorry, the term HEB is already taken by Texas groceries.
Remember when the slashdot effect was a thing that mattered?
“Each brother faces “a maximum penalty of 20 years in prison for each count,” the DOJ said.” 😬 They will be going in for a long time.
Thomas Fattorusso of the IRS Criminal Investigation (IRS-CI) New York Field Office, said that investigators “simply followed the money.” 🔎💸
Should have stolen taxpayer’s money instead, silly them
Or raped someone. .how the fuck is this more prison time than much more serious crimes.
Presumably they can claw back some of the money too
The people with money make the laws. They want to protect their money above all else, so crimes against their money are punished more harshly than others. Note this doesn’t happen when people with money steal from poor people en masse.
TBH the system barely even prosecutes sexual assault. It’s probably more likely to be raped by a cop than be helped in a rape prosecution.
Nice! Too bad they got caught, though.
No sympathy for cryptobros and trading bots.

This is a prime example of why the “code is law” selling point for smart contracts is a disaster waiting to happen. Proponents claim you won’t need lawyers, arbitrators, courts, etc, but in reality you’ll need all those and on top of that programmers to write and verify smart contracts.
“code is law” can become “might makes right” without oversight. Those who lobby against oversight are a problem.
I’ll try a simple explanation of what this is about, cause this is hilarious. It’s the kind of understated humor, you get in a good british comedy.
For a payment system you must store who owns how much and how the owners transfer the currency. Easy-peasy. A simple office PC can handle that faster and cheaper than a blockchain. But what if the owner of the PC decides to manipulate the records? No problem, you just go to the police with your own records and receipts and they go to jail for fraud. Their belongings are sold off to pay you damages. That’s how these things have worked since forever. It’s how businesses keep track of their debts.
Just one little problem: What if the government wants your money. Maybe you don’t want to pay your taxes, or some fine. Or maybe you have debts you don’t want to pay, like your alimony. Perhaps the government wants to seize the proceeds from a drug deal. They can just go to the record keeper and force them to transfer currency.
This is where cryptocurrencies come to the rescue (as it were). There are different schemes. ETH (Ethereum) uses validators. The validators are paid to take care of the record-keeping. The trick is, that you have to put down ETH as a collateral (called staking) to run a validator. If you manipulate the record/blockchain, then the other validators will notice and raise the alarm. That results in you losing your collateral.
This means the validators can remain anonymous. You don’t need to know their identities to punish them for fraud. You just take their crypto-money. They need to remain anonymous so that the government (or the mob) can’t get to them.
This is where it gets hilarious. These 2 brothers operated fraudulent validators. The stake/the collateral didn’t matter at all. The whole scheme didn’t matter. It was a horrible waste of money and effort. The indictment even details how they tried to launder the crypto. That is, how they tried to transfer it, so that it couldn’t be traced on the blockchain. The indictment even has the search queries they used to look up the info on how to do that.
The whole point of it all is that you supposedly do not need the government to prosecute anyone. If validators are kept honest by the threat of criminal prosecution, then you do not need the whole Proof of Stake scheme. You do not need the whole expensive overhead.
The only rational reason for crypto to exist, is to avoid laws; buying drugs and what not. I’m not judging. The hilarious fact is that the law knew everything about these guys.
It’s all a sham. The one thing that crypto is supposed to do: Foil the government. And it doesn’t work.
When people want to buy crypto on the blockchain, they put out a request so that a validator will execute that transaction and record it on the blockchain. So, while the request is waiting, a bot comes along and scans it. It may be that a purchase changes the exchange value of a currency. In that case, the bot adds 2 more transactions. First, to buy that currency before the original request, and to sell it afterward. The original request drives up the price in between the buy and sell, so that the bot makes a profit for its operator. The original request has to pay a little extra. That’s where the profit comes from.
Sound shady? I hope not, because that’s what the victims did.
The accused operated their own validators. At the right time, they put out their own buy request to lure in a bot. When the bot proposed the bundled transactions, their validators feigned acceptance. But then switched out the lure transaction of buying for selling.
The indictment makes a fairly good argument. It’s like there is a “contract” between these automatic systems. The trading bot wants the bundled transactions to be carried out exactly so. The validator feigns agreement, but does not follow through.
