- NSA chief Gen. Joshua Rudd reported that Anthropic's Mythos breached 'almost all' classified systems in just hours during a red-team exercise on 11 June.
- The disclosure has recast the export-control shutdown of Fable 5/Mythos 5 as a response to autonomous offensive capability, not just an API jailbreak.
- This validates government intervention, establishing a precedent for a national-security recall of frontier models based on demonstrated cyber capabilities.
