Anthropic filed two federal lawsuits on March 9 against the Department of War and more than a dozen other agencies after being designated a "supply chain risk" - a label previously reserved for foreign adversaries. The company's refusal to strip safety guardrails from Claude has set up a constitutional confrontation that cuts to the core of how the U.S. government treats its own AI industry.

Anthropic has published a detailed sabotage risk report for Claude Opus 4.6 - its first under the new RSP v3.0 Risk Report framework - concluding the model poses "very low but not negligible" risk of autonomous actions that could contribute to catastrophic outcomes. The document is notable both for what it finds and for the candor with which it describes the limits of its own methods.

A Chinese state-sponsored group used Claude to execute a largely autonomous cyberattack on 30 critical organizations - with human operators present for just 20 minutes. This was not a warning shot. It was a proof of concept.
