Anthropic's threat report shows the IRGC and the Houthis weaponized Claude for weapons development, espionage, and influence ops.

 Houthis: 
• Used Claude Code to build guidance/nav/control software for weapons instead of hiring engineers 
• Ran 3 parallel programs: a guided rocket w/ phone-class flight computer + homing guidance; a multi-stage ballistic missile targeting 2,000+ km range; an "R2000" line incl. a hypersonic glide vehicle 
• Tried to hide the weapons purpose from Anthropic and offending accounts were ultimately banmed.

 Islamic regime (surveillance targeting Jews & Israelis): 
• Built an automated OSINT "identity-profiling harness" scraping the public internet to compile intelligence-style dossiers on hundreds of individuals in Israel and the Jewish diaspora 
• Targeted Israeli government officials, private citizens, and organizations tied to Jewish communities outside Israel feeding an existing target list 
• A separate Iran-nexus actor built targeting handbooks on U.S. naval forces (personnel, ship/aircraft IDs, satellite imagery)

 Islamic regime ("soft war" propaganda, GTG-34001, ICCO/Khorasan Razavi/Bina Observatory): 
• Built doctrine manuals, personas, target databases under the "Jihad al-Tabyin" mandate 
• Impersonated an IRGC spokesperson; faked citations to CSIS, Brookings, RAND during the 2026 US-Israel-Iran war 
• Targeted the Baha'i minority and Iranian opposition figures; drafted Supreme Leader funeral logistics uploading documents and the full plan to Claude.
