AI BriefingThe New Frontier of AI Cybersecurity: The Reality After Mythos
Key point
Even small open models succeeded in detecting zero-day vulnerabilities and reproducing exploits.
Details
After Anthropic's Claude Mythos automatically detected a large-scale zero-day vulnerability, smaller open models also succeeded in detecting the same vulnerability.
In particular, models in the 3.6B~5.1B parameter class reproduced FreeBSD and OpenBSD bugs, and some models even presented creative exploit paths different from Mythos.
The key point is that AI-based security analysis is no longer the exclusive domain of only the largest closed models. This is read as a signal that even small models can achieve sufficiently meaningful results in actual vulnerability analysis and attack scenario generation.
