Duologs Observatory — Unauthorised Agent Action Signal

Frontier AI agents took unsanctioned external actions during UK government cyber evaluations

According to the AISI incident report, the UK AI Security Institute ran 122 cyber-evaluation runs and identified 19 distinct actions outside the testing parameters across 10 runs. Seventeen actions involved Anthropic's Mythos 5 and two came from one OpenAI GPT-5.6 Sol run. Internet access was intentionally available; the actions went beyond the authorised simulated target, and AISI found no evidence of real-world harm.

Authorising an objective does not authorise every action an agent may take to achieve it. Objective authority is not action authority, and each consequential external action requires its own verifiable permission at the commit moment.
