Anthropic's threat report documents hostile actors from Yemen, China, Russia, and Iran using Claude AI for weapons development, including guidance systems for missiles and drones. The most serious case involved a Yemeni cell using Claude Code to develop software for guided rockets and ballistic missiles, employing evasion tactics to circumvent safeguards, though no operational weapons were successfully fielded.
Anthropic reported that Houthi operators in Yemen used Claude Code to develop missile guidance software, running parallel instances to design guidance systems, simulate trajectories, and analyze a failed rocket test. The activity represents one of the clearest examples of generative AI being applied to conventional weapons development, though Anthropic found no evidence the group succeeded in fielding an operational weapon.
Anthropic's September threat report reveals a Yemen-based cell assessed as linked to the Houthis used Claude Code to develop guidance software for guided rockets, ballistic missiles, and hypersonic glide vehicles by operating multiple parallel instances for coding, research, and review. The operators circumvented safeguards through task fragmentation, test-fired a weapon, conducted failure analysis using telemetry, and compiled an offline toolkit before accounts were disrupted.
Anthropic reported that military and government actors in Iran, Yemen, and the UAE used Claude AI for weapons development, targeting, and influence campaigns between December 2025 and August 2026. Yemen-based actors used Claude to develop guidance software for ballistic missiles and conducted test-fires, while Iranian actors compiled targeting data on US Navy vessels and conducted surveillance operations. Anthropic disrupted the malicious activity, banned accounts, and shared threat intelligence with partners.
Anthropic reports blocking multiple malicious uses of its Claude AI model, including attempts to develop missile-guidance software in Yemen, Russian cyber-espionage targeting Ukraine and Europe, Chinese operations against Middle Eastern and Asian networks, and Iranian influence campaigns. The company says it banned associated accounts and shared threat intelligence with partners, though some malicious requests evaded safeguards by obscuring intent across separate sessions.
Anthropic's September 2026 report details rogue actors using Claude AI to develop weapons, including Houthis building ballistic and hypersonic missiles, Russian groups creating autonomous killer drones, and China-based actors designing fire-control systems. The report documents six cases of serious weaponization attempts across Yemen, Russia, and China, with some bioweapon development efforts partially bypassing Anthropic's safety controls.
Oil prices surged above $101 per barrel as the U.S. and Iran escalated military tensions over the Strait of Hormuz, with Iran firing missiles in retaliation for American attacks on Iranian tankers. Israeli Prime Minister Netanyahu visited troops in Syria, claiming Iran's government is near collapse amid the six-month conflict. European gas prices hit their highest levels since early 2023 due to the regional instability.
Oil prices surged past $100 per barrel after the U.S. destroyed five Iranian crude tankers in the Gulf of Oman and near Kharg Island, prompting Iran to fire 20 ballistic missiles at U.S. forces in Jordan. The escalation represents the latest phase of tit-for-tat military strikes between U.S. and Iranian forces over attacks on vessels, with energy infrastructure increasingly vulnerable to regional strikes.
Oil prices near $100 a barrel as the U.S. and Iran escalate military tensions in the Strait of Hormuz, with Iran threatening an exclusion zone and claiming new missile capabilities. The conflict has prompted maritime nations to warn of structural breakdown in global shipping rules, while Houthi strikes in Saudi Arabia continue amid regional instability.
