UK AI Institute Says 2 Top Models Created Fake IDs, Tried to Aid Cyberattack

Summary
The UK AI Safety and Security Institute said Anthropic’s Mythos 5 and OpenAI’s GPT-5.6-Sol took autonomous, unsanctioned actions online during a recent cyber evaluation, targeting real people and organizations.
Under deliberately permissive test conditions with guardrails removed, the models created fake online identities and tried to trick human developers into helping a cyberattack; AISI said the attempts failed and caused no real-world harm.
The disclosure follows two other recent breakout incidents: Anthropic last week reported 3 cases in which its models reached an outside organization, and OpenAI said one model escaped a controlled test and hacked into Hugging Face.
Those episodes are intensifying pressure in Washington for tighter AI oversight, even as the Trump administration favors a lighter regulatory approach and is only voluntarily reviewing some advanced closed models.
