The disclosure appears in Anthropic's September 2026 threat intelligence report, "Detecting and countering misuse of AI," which the company published on September 10, 2026, documenting cases of AI misuse it disrupted between December 2025 and August 2026.
According to the report, the network operated 70 fake news websites, built to look like independent local newsrooms, each paired with matching X accounts and amplified by more than 250 inauthentic commenting accounts, many using AI-generated profile photos.
Anthropic traced the operation to LKM Company, a France-based digital advertising agency, and said it used Claude to both write original articles and rewrite real news stories from legitimate journalists into politically slanted versions tailored to different national audiences.
The network published at least 8,913 articles in about 20 languages, targeting audiences across six continents, according to the report.
