Secure Boot's Cryptographic Defense Expires: Critical Firmware Security Threat Emerges

As Secure Boot certificates expire on June 24, Windows and Linux systems face heightened vulnerability to bootkit attacks—malware that loads before the OS, making it nearly impossible to detect or remove even after reinstalling the operating system. This cryptographic barrier is essential for protecting firmware-level attacks, and failing to update means systems lose a critical layer of defense against increasingly sophisticated malware.
