For most finance companies, if they have a whoopsie and lose money to a software boo-boo, they'll just reverse the transaction. Times when such a transaction cannot be reversed (https://www.bloomberg.com/news/articles/2021-03-19/citigroup...) are the extremely rare exception, and are adjudicated by a civil court.
Whereas if a crypto company has their wallets breached, it's almost certainly immediately irreversible.
That's why attackers never go after credit card numbers, right?
I think non-revertible payments do not really make a big difference to attackers, it just makes value extraction more efficient. Some percentage of fraudulent transactions will always make it through. So long as the funds accessible to the attacker are sufficiently large, it's still a juicy target. 10% of 200 megadollars is still 20 megadollars.
I agree with @capableweb2. They're an attractive target because they are a financial company with control over lots of value, not because of anything to do with cryptocurrencies in particular.
Just like finance companies have a different risk profile than companies generating bingo cards, crypto companies have different risk profiles than other non-financial ones. Are people arguing that this is not true or something?
