Anthropic says multiple threat groups, including the financially motivated and state-sponsored espionage groups linked to Russia and China, tried to abuse its Claude AI model for malicious purposes.

The AI company says that between December 2025 and August 2026, it recorded various forms of artificial intelligence misuse, including for cyber and influence operations, surveillance, scams, development of biological and conventional weapons, and model distillation.

Over the eight-month period, Anthropic disrupted several activities linked to the ShinyHunters collective, infamous for massive data theft attacks that typically begin with social engineering and account compromise.

An alleged French-speaking member of the group that used the handle ‘frkoo’ distributed a credential-harvesting pipeline across ten AWS EC2 workers that downloaded from multiple stores and then scanned for secrets in 1.8 million Android APKs.

“This pipeline mass-downloaded 1.8 million distinct Android APKs from multiple app-store sources, decompiled them, and scanned for hardcoded secrets with TruffleHog,” Anthropic explains.
