![]() This is a nasty vulnerability, but it takes some work to exploit it. ![]() It can affect physical PCs and virtual machines with Secure Boot enabled. Microsoft says that the vulnerability can be exploited by an attacker with either physical access to a system or administrator rights on a system. PCs running Windows 11 must have it enabled to meet the software’s system requirements. Secure Boot has been enabled by default for over a decade on most Windows PCs sold by companies like Dell, Lenovo, HP, Acer, and others. The BlackLotus bootkit is the first-known real-world malware that can bypass Secure Boot protections, allowing for the execution of malicious code before your PC begins loading Windows and its many security protections. Microsoft is currently patching a zero-day Secure-Boot bug. “Gaining the kind of control required to compromise a software build system is generally a non-trivial event that requires a great deal of skill and possibly some luck.” But it just got a whole lot easier. Consequently, MSI doesn’t provide the same kind of key revocation capabilities.ĭelivering a signed payload isn’t as easy as all that. To make matters worse, Matrosov said, MSI doesn’t have an automated patching process the way Dell, HP, and many larger hardware makers do. This raises the possibility that the leaked key could push out updates that would infect a computer’s most nether regions without triggering a warning.
