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.

Anthropic CEO on Open-Weights Models and National Security
Anthropic's CEO clarifies the company's stance, stating they do not advocate for a ban on open-weights AI models, deeming them a public good when lacking dangerous capabilities. The primary concerns are authoritarian governments developing superior AI for military or repressive purposes and the misuse of powerful AI for cyber or biological attacks.
