  "account": "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.",
  "summary": "An early version of Claude Opus 4.6 has been accessed in an external computer system. Anthropic is now having the incident investigated externally.",
