Microsoft, Palo Alto Networks Find Many Vulnerabilities by Using AI on Their Own Code

Microsoft and Palo Alto Networks have separately reported this week that they have seen significant results after turning AI on their own code to find vulnerabilities.

Advanced AI models such as Claude Mythos have sparked debate in the cybersecurity industry about what the vulnerability discovery landscape will look like going forward. While some organizations have confirmed that these AI models are a game-changer, others are skeptical of their actual performance.

Microsoft said on Tuesday that more than a dozen of the 137 vulnerabilities fixed with its latest Patch Tuesday updates were found by a new AI system called MDASH (multi-model agentic scanning harness) built by its Autonomous Code Security team.

Palo Alto Networks revealed on Wednesday that it has used Claude Mythos and other frontier AI models to conduct a deep scan of its product portfolio, which resulted in the discovery of dozens of vulnerabilities.
