White House Talks With Anthropic on Mythos Access

Overview

• After a meeting the White House called productive, the Office of Management and Budget said it is setting safeguards that could let select federal agencies use Mythos under strict controls.
• Anthropic is limiting Mythos to roughly 40 partners and created Project Glasswing to coordinate defensive testing so companies can spot and fix weak points before criminals do.
• The American Securities Association urged Treasury to halt the SEC’s Consolidated Audit Trail and delete sensitive records, warning that Mythos makes it easier to steal identities and reveal individual trading positions in the database that tracks orders and links them to named traders.
• Anthropic released Claude Opus 4.7 as a lower‑risk option, adding automated blocks on high‑risk cybersecurity requests and focusing the model on coding tasks and image analysis.
• Financial regulators in the U.S., U.K., and eurozone voiced alarm, U.S. leaders gathered Wall Street chiefs to assess the threat, and several big American banks reported internal tests while many European banks said they still lack access.
