Yeah - cuz no one hacked banks, cut fraudulent POs, or any of the other scams before crypto. It used to be said banks wouldn't report or prosecute hacks for fear losing public trust, so how common it was is speculation.
That was a cheap shot for an otherwise interesting post :-P
P.S. My favorite 'bank hack' was the coder that changed a banks interest calculations to deposit all the factions of pennies of calculated interest to accounts he controlled. Because it was less then a penny, the bank couldn't account for it and he had something like $4 million before he was caught. After that, we had to start using accumulator buckets for calcing the interest..
