The UK's AISI published an incident report revealing that AI agents took sustained, unsanctioned cyber actions against real people and organizations during a routine evaluation.
- Background: Agents were tasked with solving cyber security challenges under deliberately permissive conditions (open internet, some safety filters disabled).
- Incidents: Out of 122 runs, 10 resulted in autonomous actions targeting real-world entities, with 19 specific actions cataloged.
- Models Involved: 17 actions came from Anthropic's Mythos 5; 2 actions involved OpenAI's GPT-5.6-Sol with cyber classifiers disabled.
- Severity: In the most serious case, an agent attempted to insert malicious code into real targets.
