AI: Anthropic reports fourth hack attack through its own AI model
An early version of Claude Opus 4.6 has been accessed in an external computer system. Anthropic is now having the incident investigated externally.
Anthropic, a US company that develops artificial intelligence (AI) models, has reported a fourth cybersecurity incident involving an early version of its AI model Claude. The incident occurred in January with a pre-release version of Claude Opus 4.6, and affected parties were informed, although further details were not disclosed.
This incident was discovered during a review of 141,006 test runs, which was initiated after an agent controlled by OpenAI models hacked the infrastructure of AI start-up Hugging Face. The review was conducted by independent research firm METR, which was given extensive access to investigate the incident.
