KB5029033: Notice of additions to the Windows Driver.STL revocation list - Microsoft Support
The Microsoft Windows Hardware Compatibility Program (WHCP) certifies that drivers, and other products, run reliably on Windows and on Windows certified hardware. First reported by Sophos, and later Trend Micro and Cisco, Microsoft has investigated and confirmed a list of third-party WHCP-certified drivers used in cyber threat campaigns. Because of the drivers’ intent and functionality, Microsoft has added them to the Windows Driver.STL revocation list.
