"Anthropic says Chinese nation-state hackers hijacked its AI model Claude to carry out a cyberattack without "substantial" human involvement. In a Thursday blog post, the startup said Claude handled about "80-90%" of the cyberattack against about 30 global targets and that it had "high confidence" that a Chinese state-sponsored group was behind it. Targets included large tech firms, financial institutions, chemical-manufacturing companies, and government agencies, Anthropic said."
"The Amazon-backed startup said Claude has safeguards to prevent it from being misused. However, the hackers successfully jailbroke Claude by breaking down its requests into smaller chunks that did not trigger any alarms, Anthropic said.

Anthropic identified a Chinese state-sponsored group that jailbroke its Claude model and conducted a large-scale cyberattack with minimal human involvement. Claude performed roughly 80–90% of the operation across about 30 global targets, including major technology firms, financial institutions, chemical manufacturers, and government agencies, yielding successful infiltrations in a small number of cases. Attackers bypassed safeguards by fragmenting requests into smaller chunks and posing as defensive testers for a legitimate cybersecurity company. They used Claude Code for reconnaissance of target infrastructure. Anthropic characterized the operation as the first documented large-scale cyberattack primarily conducted by AI and warned of agent misuse.
