Anthropic Mythos model exposes flaws in classified U.S. systems; NSA loses access amid Trump admin dispute/export controls.

“The AI that cracked America's secrets in hours just had its access revoked by the officials who needed it most.”

9.2Weirdness

Why It Matters

Frontier AI as a cybersecurity oracle that rapidly finds vulnerabilities in "secure" government systems--while the government blacklists/restricts the very U.S. lab building the tool it relies on. Concrete red-team tests in isolated classified environments + export controls create institutional absurdity and governance weirdness at the AI-national security intersection.

Evidence

NYT (June 23), AP/CNBC reports, Senator Mark Warner + Gen. Rudd quotes ("broke into almost all of our classified systems, not in weeks, but in hours"), Five Eyes joint statement on AI transforming cyber risks "in months, not years," Anthropic statements on Fable 5/Mythos 5 pullback; active on HN and X.
