I’ve been waiting for this. Given llm aptitude for offensive security hacks it was just a matter of time. I wager most alt coins are compromised at this point.
Intetested to know then why you'd think some are not.
A lot of altcoins were forks of popular code bases. ie btc and eth. Some code bases pulled in bug fixes from upstream, others drifted or were not maintained. Others were greenfield projects without as many eyes. A lot of targets imo.
