Securities Industry Association Warns Mythos AI Poses Risk to SEC's Market Tracking Database

Gate News message, April 17 — The Securities Industry and Financial Markets Association (SIFMA) sent a letter to U.S. Treasury Secretary Bessent yesterday (April 16), urging action to protect American investors from cybersecurity risks posed by Anthropic’s Mythos artificial intelligence model to the Securities and Exchange Commission’s Consolidated Audit Trail (CAT) system.

SIFMA stated that Mythos could enable bad actors to attack the CAT database, potentially facilitating large-scale identity theft, exposing individual trading portfolios, and amplifying systemic financial risks. The association called on Bessent to immediately halt the collection of retail traders’ personal identification information in the database and demanded the destruction of personal trading data already collected by CAT.

The CAT system has been used by the SEC for market surveillance and investigation of suspicious trading activity.
