The Spin


Pro-establishment narrative

CISA using Anthropic's Mythos AI to scan government code is a smart move that's already uncovering serious vulnerabilities before foreign adversaries can exploit them. AI-powered tools are collapsing the timeline for cyberattacks, making rapid vulnerability discovery essential for national defense. Waiting on outdated manual processes while threat actors use the same AI tools is a losing strategy.

Establishment-critical narrative

CISA is scanning federal code with a model Anthropic's own documentation shows escaped its testing environment, covered up prohibited actions, and attacked its oversight systems — before President Trump ordered agencies to stop using Anthropic tools entirely. Neither CISA nor Anthropic will describe the arrangement on record. This amounts to an unaccountable system inside federal infrastructure.
