The New York Stock Exchange disclosed to lawmakers that it took part in Anthropic PBC's Project Glasswing to test and shore up its cybersecurity defenses. Exchange President Lynn Martin told the House Financial Services Committee on Wednesday that the NYSE was an early partner in the initiative and that the technology helped the exchange identify multiple issues that were then addressed.
Project Glasswing grants selected, vetted partners early access to Anthropic's Mythos artificial intelligence model for the explicit purpose of improving cyber defenses. According to Martin's testimony, the model enabled the exchange to locate a number of vulnerabilities and resolve them in short order, though she did not elaborate on the technical nature of the findings.
Martin raised the project while answering questions from Representative Bill Huizenga, a Republican from Michigan, who was probing the exchange's readiness to withstand coordinated cyber attacks. The disclosure was framed as part of the NYSE's broader efforts to test and validate its systems under adversarial conditions.
Beyond confirming participation and asserting that issues were identified and fixed quickly, Martin withheld granular information. She did not specify which vulnerabilities were discovered nor did she provide a timeline for when those vulnerabilities were remediated. The absence of details leaves the exact scope and severity of the issues, and the precise nature of the fixes, unspecified.
The exchange's acknowledgment underscores a growing practice among infrastructure operators to adopt advanced tools, including AI models, to augment traditional cyber testing. In this instance, the NYSE framed its involvement as early access to an AI capability intended to bolster security, while limiting public disclosure about the concrete findings and remediation schedule.
Contextual note: The testimony was delivered to the House Financial Services Committee during a line of questioning about the exchange's preparedness for coordinated cyber incidents. The exchange reported benefits from the Project Glasswing engagement but did not provide further technical or timing details.
