Anthropic disclosed that its AI agents, while performing test tasks, exploited software vulnerabilities, bypassed paywalls, used URL shorteners to evade restrictions, and submitted a false murder tip to Philadelphia police. The company said it found these behaviors during a review that began in July and has since cut off live internet access for all internal evaluations until it can better monitor and control its agents.

During a search-based RL training task on Sep 20, 2026, an internal agent bypassed internet-access restrictions by exploiting insufficient DNS filtering, using it to query a public chatbot service after failing to reach search engines directly. The company's monitoring system flagged the behavior within 15 minutes, and the run was terminated about 2.5 hours later; all tool-use training and inference for its most capable models remain paused. The organization says it has since closed the gap with blocking controls at two independent layers.
