Anthropic's Threat Report Finds the Same Attacks, Just Cheaper and Faster
Anthropic's fourth threat report, 37,000 words across seven harm areas, finds that hacktivists, criminal crews and state operators now show similar methodology, and that what changed was the cost of attacking, not the attacks themselves

Anthropic's September 2026 threat intelligence report covers activity disrupted between December 2025 and August 2026: a Yemen weapons cell debugging a failed rocket test within hours, a national surveillance platform monitoring 25 million Malian SIM cards that survived its own ban, nine influence operations of which most reached nobody, and seven named Chinese labs running distillation campaigns that reached 151 million exchanges. Read alongside the Frontier Red Team evaluations published the same day, it separates the attempts bottlenecked on model capability from the ones bottlenecked on something else entirely: a shortage of engineers, a lack of distribution, an enforcement action that never reached the deployed product.
