UEFI bootkit infected fully patched Windows machines

A UEFI bootkit managed to compromise fully patched Windows machines, raising questions about whether Microsoft is to blame for the vulnerability. Reporting by Ars Technica connects the incident to BlackLotus, a known bootkit that exploits weaknesses in the UEFI secure boot process. Security commentators are debating whether the fault lies with Microsoft's firmware signing and patching practices, and what users can do to protect systems against boot-level malware that survives reinstalls.
Why now: A new bootkit attack bypassing Windows patches reignites debate over Microsoft's security responsibility and UEFI vulnerabilities.
