What it says
- Microsoft uses its multi-model agentic scanning harness (MDASH), which combines several models, including third-party ones specialized in finding vulnerabilities, to review critical Windows binaries.
- Candidates are validated through a “debate” among several model families and then move on to a verification process specific to Windows; assessment and fixes remain in the hands of engineers.
- The announced consequence: customers will see more security updates with every release. Microsoft presents this as a sign that defenders are finding and fixing more flaws.
- It recommends speeding up deployment with Windows Autopatch and hotpatch (in Intune), keeping endpoint protection software up to date, and connecting servers outside Azure through Azure Arc.
- Two months later, the Zero Day Initiative's monthly analysis counted 972 new CVEs from Microsoft in the September 8 update, another record. Its author, Dustin Childs, describes it as “the new normal.”
