All that AI has done is to lower the bar of entry for criminal activity. Which is a concern, but it's not the primary concern. The primary concern remains that so much critical infrastructure is poorly secured.
Perhaps the latest models change that relationship in a meaningful way.
Don't get me wrong I have general disgust towards these companies that are trying to get regulatory capture on AI when they can't even secure their own systems. I believe if people know that a random AI agent can hack their systems they will put in a lot more effort into making sure it doesn't happen. This is a personal example, but I didn't really care about securing few systems as I knew no human would be ever interested in finding a vulnerability in proprietary software, however, AI has no concept of that and would hack a random rpi server running a completely undocumented unknown API just because it can't distinguish value and it costs nothing.
It's like a new form of spam. Only far more dangerous.
