Anthropic's September threat-intelligence report documents real cases of Claude being misused between December 2025 and August 2026.
In one, a single French-speaking actor used Claude in spring 2026 to run a pro-Russia, anti-France influence operation aimed at European political parties, media and think tanks. Claude sat inside a human-edited pipeline as a sub-editor and content writer. The operator told it to work in set talking points and to strip out the formatting habits that make ai-written text easy to spot.
Why it matters
Most talk about ai and misinformation is speculative. This is a documented, disrupted case with specifics, including a deliberate attempt to make the model's output harder to identify as machine-made.
It's the other side of ai getting cheaper and easier to reach. When the tools are this accessible, a small, motivated operation can punch well above its weight.
