Anthropic Launches Project Glasswing with Tech Giants to Tackle AI-Driven Cybersecurity Risks

Anthropic, along with a coalition of leading technology companies, has launched Project Glasswing, a major industry initiative aimed at strengthening global cybersecurity in response to rapidly advancing artificial intelligence capabilities.

The effort brings together firms including Amazon Web Services (AWS), Apple, Google, Microsoft, NVIDIA and Palo Alto Networks, among others, to secure critical software systems against emerging AI-driven threats.

At the centre of the initiative is Claude Mythos Preview, an unreleased frontier AI model developed by Anthropic. The model has demonstrated advanced capabilities in identifying and exploiting software vulnerabilities—skills that, according to the company, now rival or exceed those of most human experts.

Anthropic said the model has already discovered thousands of high-severity vulnerabilities, including flaws in major operating systems, web browsers and widely used software components. Some of these vulnerabilities had gone undetected for decades despite extensive testing and human review.

"Mythos Preview has already found thousands of high-severity vulnerabilities, including some in every major operating system and web browser. Given the rate of AI progress, it will not be long before such capabilities proliferate, potentially beyond actors who are committed to deploying them safely," it said.

Project Glasswing aims to channel these capabilities toward defensive cybersecurity. Participating organisations, along with more than 40 additional partners, will use the model to scan and secure both proprietary and open-source systems.

Anthropic has committed up to $100 million in usage credits for the initiative, along with additional funding for open-source security efforts. Industry leaders involved in the project emphasised the urgency of adapting to AI-driven threats.

“Providers of technology must aggressively adopt new approaches now, and customers need to be ready to deploy. That is why Cisco joined Project Glasswing—this work is too important and too urgent to do alone,” Anthony Grieco, Cisco SVP, Chief Security & Trust Officer, said.

"We've been testing Claude Mythos Preview in our own security operations, applying it to critical codebases, where it's already helping us strengthen our code. We're bringing deep security expertise to our partnership with Anthropic and are helping to harden Claude Mythos Preview so even more organizations can advance their most ambitious work with security that sets the standard,” Amy Herzog, AWS Vice President and CISO said.

"By giving the maintainers of these critical open source codebases access to a new generation of AI models that can proactively identify and fix vulnerabilities at scale, Project Glasswing offers a credible path to changing that equation. This is how AI-augmented security can become a trusted sidekick for every maintainer, not just those who can afford expensive security teams,” Jim Zemlin, The Linux Foundation CEO, added.

Experts warn that AI is dramatically lowering the barrier to discovering and exploiting vulnerabilities, potentially enabling faster and more sophisticated cyberattacks. However, the same technology also offers a powerful tool for identifying and fixing flaws at scale.

"We do not plan to make Claude Mythos Preview generally available, but our eventual goal is to enable our users to safely deploy Mythos-class models at scale—for cybersecurity purposes, but also for the myriad other benefits that such highly capable models will bring," Anthropic also added.
