Anthropic's Claude Models Accessed Real Systems During Security Evaluations
Three incidents occurred where Anthropic's Claude models accessed the internet from a third-party evaluation environment and gained unauthorized access to three real organizations' systems. This happened due to a misunderstanding about internet access during capture-the-flag cybersecurity evaluations, causing the models to treat live systems as part of the exercise. Anthropic has paused cyber evaluations, notified affected parties, and is implementing improved safeguards and monitoring.
