Anthropic Report: Military-Grant Researcher Rerouted Refused Bio Requests to a Rival Model

ns123abc · x · 2026-09-11

Anthropic published its September 2026 threat intelligence report covering misuse disrupted between December 2025 and August 2026 across seven harm areas: cyber operations, influence operations, surveillance, scams and fraud, biological misuse, conventional weapons, and illicit distillation. Threat actors included suspected state-sponsored groups, criminals, and commercial spyware vendors. Aside from one distillation case, none involved Fable or Mythos-class models.

A highlighted case: a researcher funded by a military research institute used Claude for gain-of-function research on chikungunya virus targeting transmissibility and immune evasion — requests Claude refused were successfully rerouted to a competitor's more permissive model, underscoring the report's point that "sophisticated attacks no longer require sophisticated attackers."
