Payward, the parent company of cryptocurrency exchange Kraken, has become the first reported crypto firm to join Anthropic’s Project Glasswing, gaining access to the AI model Claude Mythos for identifying security vulnerabilities. This move signals a growing trend of crypto companies leveraging advanced artificial intelligence to bolster their cybersecurity defenses.
Payward will utilize Claude Mythos to scan its own systems and third-party open-source software for security flaws. Identified vulnerabilities in external projects will be reported to their respective maintainers, aiming to strengthen the broader crypto ecosystem.
This development follows an open letter sent last week by over 40 Bitcoin and crypto companies, including Kraken, to leading AI labs such as Anthropic and OpenAI. Organized by the Bitcoin Policy Institute, the letter urged AI developers to provide trusted access to their most powerful models for qualified security researchers, emphasizing the need for defenders to access frontier AI to proactively find and fix vulnerabilities before they can be exploited.
Project Glasswing, launched by Anthropic in April and expanded in June, is a cybersecurity program that provides vetted organizations with access to Anthropic’s AI models for vulnerability detection. Partners in the program have reportedly uncovered thousands of high- or critical-severity vulnerabilities since its inception. For example, Mozilla reported in April that Claude Mythos identified 271 vulnerabilities in the Firefox browser during testing.
Payward’s adoption of Claude Mythos is framed as a strategy to address the inherent asymmetry in cybersecurity, where attackers need to find only one flaw, while defenders must protect against all potential weaknesses. The company indicated that AI models can analyze code at machine scale, potentially identifying flaws before exploits can be developed.
Payward’s initiative underscores the increasing reliance on AI within the crypto industry for security. While AI offers powerful new tools for defense, the broader implications of its use in cybersecurity, including potential misuse, remain a subject of ongoing discussion. The specific details of vulnerabilities discovered and Anthropic’s response to the industry’s call for broader access are areas that may likely see further developments.
