Detecting and Countering Malicious Uses of Claude: March 2025

Anthropic Updates Usage Policy: Agentic Use, Cybersecurity, and Political Content

Anthropic has revised its Usage Policy effective September 15, 2025, with changes addressing agentic and cybersecurity risks, political content restrictions, law enforcement use clarity, and high-risk consumer-facing requirements. New sections explicitly prohibit malicious computer/network compromise activities while supporting legitimate security research, responding to the rapid expansion of agentic tools like Claude Code and Computer Use. The policy also narrows its previous blanket ban on political content to focus specifically on deceptive or voter-targeting uses, enabling legitimate civic and policy research. High-risk safeguards (human-in-the-loop, AI disclosure) are clarified to apply only to consumer-facing outputs, not B2B interactions.
