Anthropic has published an update on Project Glasswing, a cybersecurity initiative launched in April designed to combat AI-related cyberattacks. Powered by the unreleased Claude Mythos Preview model, Glasswing has enabled partners to discover over 10,000 vulnerabilities within a month of its launch. The company stated that most partners reported finding hundreds of critical and high-severity vulnerabilities in their software using the model.
The report emphasized that partners experienced a significant increase in their rate of bug discovery, with Cloudflare identifying 2,000 bugs, of which 400 were classified as high or critical severity. Mozilla also indicated that it fixed 271 vulnerabilities in Firefox, marking a tenfold increase compared to findings from an earlier Claude model.
Microsoft announced that patch releases will “continue trending larger for some time,” attributing this in part to bugs discovered with Mythos Preview. Additionally, Anthropic utilized Mythos Preview to examine 1,000 open-source projects, uncovering 6,202 high and critical severity vulnerabilities out of a total of 23,019.
A security research firm recently claimed it was able to breach macOS leveraging Mythos’ capabilities, though this claim was not included in the official report. Anthropic noted it has not yet released Mythos Preview publicly due to insufficient safeguards against potential misuse, but anticipates launching “Mythos-class models” as security measures improve.
To enhance Project Glasswing‘s reach, Anthropic plans to collaborate with various partners, including the US government. Current partnerships involve companies such as Amazon Web Services, Apple, CrowdStrike, Google, JPMorgan Chase, NVIDIA, and Palo Alto Networks.
Financially, Anthropic is reportedly nearing its first profitable quarter since its inception in 2021. The Wall Street Journal reported the company is on track to generate $10.9 billion in revenue, with an operating profit of $559 million for the quarter ending in June. However, the company does not expect profitability to continue in future quarters as it aims to invest in additional computing resources and other operational expenses.
