Yea, we wouldn’t want anyone doing anything illegal with crypto… 🙄
“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
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.
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.
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.
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.
by fraudulently gaining access to pending transactions
That makes no sense to me. The mempool is public, everyone can see pending transactions.
Because it’s not the public mempool. It’s a private MEV mempool that people pay to add their transactions to for special priority or conditional inclusion. For instance, asshole profiteers can use it to sandwich attack traders to siphon off “market inefficiencies” or some people just want immediate front of the line inclusion in the next block.
Presumably they exploited something in this MEV system (completely unrelated to the Ethereum protocol) that allowed them to see the pool and they shouldn’t have. Wish I knew more but everything I read was incredibly vague and misleading.
It’s a private MEV mempool
Are you sure there is such a thing? My understanding was that they just submit their sandwich transactions to the mempool with higher and lower gas respectively to achieve their desired priority ranking. Could be wrong though.
I’m sure, yes. If you submit to a public mempool, you have no guarantees that your two transactions will land on either side of the target transaction in the same block (They likely won’t). You need to leverage conditional transactions with MEV so you guarantee the miner will select and position your transactions where you need them. In this case, before and after the target transaction.
Check out the Ethereum Foundation’s page on MEV for more info.
Let them eat MEV bot operators.
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.
Remember when the slashdot effect was a thing that mattered?
I’m honestly very surprised that site is still around. Like digg.
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.
It’s a victimless crime really.
It is wrong to criminalize him. He found a bug and got a reward. Bring him in to fix the bug and to make it better. If you start scaring away people hunting for bugs and exploits for fun you will end up being exploited by a much nastier adversary
Edit: I did more research and it seems like there was some questionable actions such as creating a bunch of fake shell companies and crypto exchanges. This wasn’t a “bug” as the title is clickbait.
not stole. Were given.
If code is law, then they just found the right way to ask. And the code gave the money to them, because they asked nicely.
Code isn’t law. The article above does a bad job of explaining it and makes it sound like it was just a weekend bug find. It wasn’t a bug, it was them setting up a bunch of fake entities misdirect funds.
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.
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.
Man - that comma in the second sentence murdered my brain. Excellent synopsis though.
That sounds a lot like what I understood how etrade platforms like Robinhood work when I was reading up on the GME shorts fiasco.
I definitely only have a surface level understanding of it, but it sounded like the stock brokers have a buffer in-between the transaction request to buy/sell, and they first try to handle that locally within their portfolio, before expanding to external trades. And if there’s a favorable internal trade, brokers like Robinhood siphon out a little something something for themselves.
Sounds like people are getting busted for doing essentially the same thing Wallstreet has been doing for decades. Again.
It reminded me of high-frequency trading.
Mind, the people who do that are the victims here!
I didn’t explain how exactly they were harmed. It’s actually kinda funny, too.
It costs virtually nothing to create crypto-tokens. So that’s what people do. Do some wash trades, slip some money to influencers to hype their new token as the next big thing, then offload the whole supply and run with the money. The “investors” quickly discover that these tokens are only good for one thing: To sell to a greater fool. At that point, there are no more buyers.
The accused obtained such useless tokens. The indictment doesn’t say how. I guess they simply bought it for next to nothing.
Effectively, they tricked the victims’ bots into buying these tokens at face value. The victims were left with crypto supposedly worth $25 million but in reality unsellable. If this was stealing $25 million, then I wonder about the legality of selling these crypto tokens in the first place.
Eventually, all crypto is like that. Some cryptocurrencies are used as payment systems, but eventually something better must come along. Then that currency becomes unsellable. Someone must always be left holding the bag, as it is said in crypto circles.
I think they are guilty of fraud. But I do wonder: If we are to accept that leaving someone with worthless crypto is equal to stealing money, what does that mean for the legality of crypto as a whole?
Isn’t that just ‘high frequency trading’?
Wtf why is this considered illegal at all?
The article leaves out information. Basically they set up fake crypto exchanges and committed fraud
