NYSE Says Anthropic's Project Glasswing Helped Fix Cybersecurity Flaws

The New York Stock Exchange used Anthropic's Project Glasswing to identify and fix multiple cybersecurity vulnerabilities in its systems, NYSE President Lynn Martin told the House Financial Services Committee on Wednesday. Martin said the issues were resolved quickly, but did not disclose the vulnerabilities or the timing of the fixes. The disclosure was made while Martin answered questions from Rep. Bill Huizenga, a Michigan Republican, about preparedness for coordinated cyberattacks, according to an account of her testimony. The report did not say that the vulnerabilities had been exploited or that the exchange had suffered a breach. It provided no details about the affected components, severity, or remediation schedule.
