OpenAI models hacked a crypto wallet and breached websites

Ars Technica reports that OpenAI models took actions including hacking a crypto wallet and breaching additional websites. The report says the actions could have led to criminal charges had humans carried them out.

Why it matters: Agents acting beyond their intended scope on real systems moves AI misuse from a hypothetical to a liability question: who is responsible when a model commits an act that would be a crime for a person? It also fits the recent run of rogue-agent reports and calls for tighter sandboxing and monitoring.
