Then, the magician said "Abracadabra!" and poof! the money is gone.
> The company also offered a bug bounty to the hacker of 20% of the stolen funds.
Would that give them immunity from prosecution if they ever catch him. If not, what's the upside for the hacker to return anything back?
They can certainly offer to not call the police, but if a serious crime were committed, the police don't need to have the victim cooperate.
That's what I remember as well, but thought maybe it's different in different countries, or there is some other kind of cleverness behind the offer. Otherwise, it makes them look kind of silly.
Murder is typically more serious.
I guess that could work if no customers are affected. If customers want to get their money and it's all there for everyone, it's all good. But if it isn't, it would be awkward to tell them "we don't have your money, we bought this expensive security audit for $10M and now you only get 20% of your deposit back".
Interestingly enough, they are sort of taking the side of the hacker then against the customer. Customers can go to the police and they'd laugh at them "you put your money in Abracadabra, and now you complain that, poof! your money is gone, as if by magic? Did we get that right?"
There is a general belief among a lot of crypto folks that "if it's on chain, it's fair game" and you can make these kind of deals etc but as far as I can see, there's absolutely no basis for that in law. If law enforcement/regulators start to take actions they can do so for any case they suspect of being market abuse irrespective of whether the parties agreed some kind of deal. That is certainly my read of both the US and UK/EU regulations, which are the two cases I'm aware of. Neither of them have any sort of carve out to allow participants to make a bilateral arrangement to give someone a post-hoc waiver for some act that would otherwise be considered abuse.

Does anyone have more details about how (or if) Tornado Cash was involved/used in this attack?
The attack was able to happen as a result of two separate bugs.
First, a user was able to use something as collateral with a price that could be manipulated. This allowed them to make the collateral to instantly manipulated to appear worth less than the amount borrowed, allowing it to be liquidated.
The second bug was that they had code that should not allow a user to do a series of interaction with the contract that end in bad debt for the user, however since they were able to liquidate their own bad debt from inside the series of interactions, the liquidation cleared out the bad user debt, and moved it to bad protocol debt. This made it so the whole process was checked at the end of the transaction, the user debt looked fine.
Or I could be slightly wrong - it was an usually gnarly attack.
Team backdoors in code to steal funds tend to be obfuscated, and access to run them locked down. This is quite different than a hack that exploits "well intentioned" code. I think very few actual exploits are by the team - there's just much easier ways to steal funds than leaving a bug open in the world for a long period of time that anyone could find and use.
There was a "real crypto economy" back in the days of the silk road. So I would say that the real cryptocurrency economy has been tried, and it was doing alright until they got busted by the feds. But the reason we don't have a crypto economy today is that drug dealers got drowned out by the more popular get-rich-quick schemers.
But I agree that Silk Road was an economy. Just like slave trading and other human trafficking is an economy.
We do still have an illegal cryptocurrency economy. It's more tilted towards the ransomware economy than drugs, though. So it's not just pyramid schemes.
But I'm sure crypto drug kingpins and murderers like Ross Ulbricht are still out there. In fact recently I listened to a money podcast that investigated if hitmen paid in cryptocurrency on the dark web were a real thing. I can't find it now, but the answer was that most are scams, but yes actually there's a nonzero number who will kill the person.
But back to my point: Most people talking about the cryptocurrency utopia (though most have given up on that, instead shifting to "it's a store of value!"), when they (de facto) say "real cryptocurrency economy has not been tried" mean the non-traditionally-criminal economy. So I also don't think that what I said was wrong. It depends what you mean by the word "real". :-)
