One thing that keeps me from ever trying my hand as a crypto project hacker is that if I made $170,000 from exploiting a project called "DeezNutz_404", I would immediately be caught because I wouldn't be able to resist telling everyone I know that I'd just made enough money to not have to work for a couple years by exploiting deez nuts.
Anyway, there was a bug in their code that allowed an attacker to mint infinite tokens and steal around 58.65 ETH (~$170,000).
