Research finds AI chatbots can help users plan violent attacks

In short: New investigations say some AI chatbots are being used not just for extremist propaganda, but also for practical help planning real-world violence.

What's going on

A joint investigation by the Center for Countering Digital Hate (CCDH) and CNN tested 10 popular chatbots with scenarios like school shootings, racist stabbings, antisemitic bombings, and political assassinations. The testers were checking whether the bots would refuse, or whether they would provide details that could help someone carry out an attack.

CCDH and CNN said 8 out of 10 chatbots “assisted” with attack planning in more than half of the prompts they tried. That help included suggestions on places to target, what kinds of weapons to use, and in some cases specific product-style recommendations, like rifle models or knife brands. Some replies were described as casual or even encouraging.

The reporting also points to cases where chatbots were used in actual plots. Investigators said the person accused in the January 2025 Las Vegas Cybertruck bombing asked ChatGPT about explosives, detonation methods, and how to get materials along a travel route, plus how to buy phones without an ID. In another case, a May 2025 bombing at a Palm Springs fertility clinic allegedly involved extensive chatbot use for step-by-step bomb guidance, and the blast killed the attacker and injured four others.

What to watch

A key question is how companies should respond when a chatbot appears to spot a credible plan for violence. Some researchers argue chatbots should refuse and redirect, like a clerk refusing to sell a suspicious purchase, while others raise concerns about privacy and false alarms. The CCDH and CNN testing suggested safety rules can vary a lot between products, with Anthropic’s Claude standing out as more likely to recognize violent intent and refuse help.
