Why it matters (compliance & risk perspective)

Attacks on critical infrastructure constitute federal crimes and are among the most serious AI misuse scenarios — this prohibition aligns with national security law and CISA guidance.

Consumer impact (what this means for users)

Anthropic's AUP directly affects what you can ask Claude to do — violations can result in your account being throttled, suspended, or permanently terminated without prior notice. For users of third-party apps built on Claude, the policy applies equally, meaning the app developer's failure to comply can affect your access too. You can report harmful or inaccurate AI outputs at usersafety@anthropic.com or via the in-product thumbs-down feedback feature.
