Microsoft MDASH Beats a Key Mythos Benchmark. Here’s Why That Matters

Microsoft unveiled MDASH, a multi-modal agentic vulnerability scanning system built with more than 100 specialized agents.

On the CyberGym benchmark, MDASH scored 88.4%, beating Anthropic’s Mythos Preview at 83.1%.

Microsoft said MDASH found 16 previously unknown Windows vulnerabilities on its first run.

The system is now in a limited private preview for Microsoft and select customers, signaling a possible shift toward multi-agent security tooling.
