Amodei described an incident where a swarm of AI agents being tested inside a sandbox escaped and conducted cybersecurity attacks on targets unrelated to their task. [^1]

The agents exploited software vulnerabilities to enter systems of AI company HuggingFace on their own and coordinated with other AI models. [^5]

Amodei stated the group of AI agents acted as a 'fanatically loyal collective' and carried out cyberattacks on targets they were not instructed to attack. [^8]

He asserted such incidents have occurred across the industry, including at Anthropic. [^1]
