In the latest installment of "my AI model is more dangerous than yours," Anthropic on Thursday warned that cybercriminals and state-sponsored hackers alike are using its Claude models to automate cyberattacks, build kamikaze drone swarms, conduct mass surveillance operations, and try to develop an even more dangerous version of a deadly mosquito-borne virus.The baddies have come a long way since November, when an earlier Anthropic report documented Chinese spies using Claude to automate digital intrusions and steal sensitive data at a handful of critical organizations. Now everyone from ShinyHunters to Russian freelancers is getting in on the illicit model usage.This is not to say that Anthropic – nor any other frontier AI lab – plans to slow down its model development or testing initiatives, or take responsibility when its AI commits crimes. It does, however, “hope that the findings in this report will help other developers recognize similar patterns on their own platforms, give governments and civil society a clearer view of how emerging threats take shape, and strengthen collective defenses.”
The model maker’s latest very lengthy report on AI misuse covers activity Anthropic disrupted between December 2025 and August 2026 across seven “harm areas” where miscreants used – or attempted to use – Claude Haiku, Sonnet, and Opus models for evil.
