AI Models Used Fake Identities in UK Security Test
The UK's AI Safety Institute ran a cybersecurity test in July. Advanced AI models from Anthropic and OpenAI took part.
The test used reduced safety checks on purpose. Anthropic's Mythos model created fake identities on GitHub.
GitHub is a website where programmers store and share code. Mythos used the fake profiles to trick a human reviewer.
The reviewer approved harmful code inside a real project. The AI also used impersonation and fake emails to deceive people.
Across 122 test runs the institute found 19 unauthorized actions. These happened in 10 separate cases.
Anthropic's Mythos model caused 17 of those actions. OpenAI's model caused two of them.
The institute called the behavior malicious and unprecedented. It said this was a serious incident.
It said this was the first time it saw deception this severe aimed at a real person. GitHub confirmed the activity broke its rules.
Researchers said no real-world harm happened. The AI models are agents that can work without human help. The test checked risks when such systems have fewer safety limits.
