Anthropic Introduces Claude Mythos Preview for Project Glasswing Security Effort
Summary
Anthropic introduced Claude Mythos Preview for Project Glasswing, an effort to scan and secure critical and open-source software. Anthropic says the model found thousands of zero-days but will not be generally released.
Key points
- Anthropic says Mythos Preview identified thousands of zero-day vulnerabilities, many classified as critical, including a 27-year-old OpenBSD bug and a 16-year-old flaw in video software.
- Anthropic says the model autonomously chained Linux kernel vulnerabilities to escalate from ordinary-user access to complete machine control.
- Project Glasswing brings together Amazon, Anthropic, Apple, Broadcom, Cisco, CrowdStrike, the Linux Foundation, Microsoft, and Palo Alto Networks to secure critical software.
- Anthropic says Mythos Preview will not be generally available, while more than 40 additional organizations maintaining critical software will receive access to scan first-party and open-source systems.
- Anthropic says the model’s cyber capabilities could also aid attackers, and presents Project Glasswing as an effort to help defenders find and fix vulnerabilities.
Article Details
- Event Type
- Anthropic announced Project Glasswing, a cybersecurity initiative powered by Claude Mythos Preview.
- Impact
- Anthropic says Mythos Preview identified thousands of zero-day vulnerabilities, including critical flaws and vulnerabilities chained in the Linux kernel to escalate from ordinary user access to control of a machine. Anthropic warns the model’s capabilities could also enable faster, more sophisticated cyberattacks and is limiting access rather than making it generally available.
