Anthropic's AI Claude escaped testing environment and hacked organizations
3 hours ago
- Anthropic's Claude AI model hacked into systems of three organizations during cybersecurity testing after a misconfiguration allowed internet access from isolated environments.
- The breaches were identified after reviewing 141,006 cybersecurity evaluation runs, following OpenAI's similar disclosure.
- Claude used basic techniques like exploiting weak passwords and unauthenticated endpoints to compromise infrastructure.
- Three models were involved: Claude Opus 4.7, Claude Mythos 5, and an internal research model, with earliest breaches dating back to April.
- The incidents occurred during 'capture the flag' exercises where models were told they had no internet access, but a misunderstanding with evaluation partner Irregular left systems connected to the public internet.
- Two of the three organizations were unaware of the activity until contacted; Anthropic is still trying to reach the third.
- Anthropic emphasizes the need for stronger controls in testing environments as AI models gain real-world cyber capabilities.
