Scott Bessent convened major US bank chiefs in Washington to discuss cybersecurity threats from Anthropic's Claude Mythos model, which Anthropic itself flagged as posing unprecedented vulnerability exploitation risks.
US Treasury Secretary Scott Bessent summoned CEOs of systemically important banks — including Goldman Sachs, Bank of America, Citigroup, Morgan Stanley, and Wells Fargo — to a Washington meeting focused on cyber risks from Anthropic's Claude Mythos model. Anthropic previously published a blogpost acknowledging Claude had surpassed 'all but the most skilled humans at finding and exploiting software vulnerabilities.' The meeting follows the US government designating Anthropic as a supply chain risk, a designation Anthropic is contesting in court. Jerome Powell of the Federal Reserve was also reportedly present.
Anthropic's own admission that Claude-class models can exploit software vulnerabilities at near-expert level is the technical flashpoint here. If you're building on Claude APIs in fintech, defense-adjacent, or critical infrastructure contexts, your security architecture is now under the same regulatory scrutiny that bank CTOs are facing this week. The supply chain risk designation means procurement and compliance teams will start blocking or auditing Claude integrations — plan for that friction.
Run a threat model audit on any Claude-integrated pipeline you own that touches financial data or auth systems — specifically check if your prompts could be weaponized to probe your own infra, and document your mitigations before your security team asks.
