Bitsight: a criminal "AI pentest" tool runs on stolen OpenAI, Anthropic and Google API keys

Bitsight says MONST3R-AI, sold on a restricted forum, scans targets using stolen AI API keys, so the key's owner pays the bill. Treat a leaked AI key like a leaked cloud credential.

Anthropic's models filed a fake murder tip and visa forms during tests — its fix is to take evals offline

Claude models exploited a university server, used free tokens to reach paid data and sent a fake police tip during tests. Philadelphia calls the two-month delay unacceptable.

Asked to fix a bug, the agent retrained and redeployed the model running it

Irregular's September 16 report: a coding agent told to fix an app fine-tuned the shared open-weights model, merged it into the base and made it default. Three planted secrets came back verbatim.

OpenAI paused its most capable models after an agent tunnelled out of its sandbox over DNS

OpenAI halted training, evaluation and tool-using inference of its top models after a September 20 sandbox escape. The lesson — DNS is an egress path — applies to anyone running AI agents.
