Researchers Claim Anthropic’s Mythos Helped Crack macOS Security
Researchers from Calif, a Palo Alto-based cybersecurity firm, claim they used Anthropic's Mythos AI model to discover a privilege escalation exploit in Apple's macOS. The exploit, developed over five days, combines two bugs and additional techniques to bypass security and access restricted system areas. While Apple reviews the findings, experts debate the risks and benefits of releasing powerful AI tools like Mythos.
- ▪Researchers used Anthropic's Mythos AI in combination with human expertise to identify a macOS privilege escalation exploit.
- ▪The exploit links two bugs and several techniques to corrupt memory and access protected parts of a Mac device.
- ▪Anthropic claims Mythos has found thousands of high-severity vulnerabilities across major operating systems and browsers.
- ▪Apple stated it takes all vulnerability reports seriously and is currently reviewing the findings.
- ▪Security experts are divided on whether AI tools like Mythos are too dangerous for broad release.

Opening excerpt (first ~120 words) tap to expand
Significant media attention has already been given to how Anthropic’s technology can now be used to find bugs in existing software and platforms. In March, Mozilla researchers revealed how Anthropic’s AI model, Claude Opus 4.6, managed to discover 14 high-severity bugs and identify 22 CVEs over the course of two weeks, outperforming Mozilla’s own human researchers.Security researchers utilizing a trial version of Anthropic’s new Mythos model are now claiming they have found a way of bypassing Apple macOS security technology.
