I don't think this is a paperclip factory moment. IIUC, it's an agent whose job it is to identfy and abuse exploits and that's exactly what it went off and did. The problem isn't anything AI specific, the problem is OpenAI's incompetence in their research leading to a lab leak. Just incompetence demanding regulation.
Read the exploitgym docs. It's not a "find the flag, it's somewhere.". Its a "here's some vulnerable source code and an input that triggers a crash; turn it into a full exploit." It also verifies at the end, using another agent, that the hacking agent actually used the intended vulnerability.
So going to find the Vulnerability's description on a third party website is clear cut reward hacking
