Deadline Approaches for Updating Secure Boot Keys for Windows and Linux Users

Windows and Linux users are required to update their cryptographic keys to protect against firmware-based UEFI infections. Starting June 24, three Microsoft-signed certificates that verify firmware and software during system boot will expire. These certificates are essential for Secure Boot, which checks the digital signatures of code that loads during startup to ensure it comes from a trusted provider. Secure Boot aims to prevent bootkits, a type of malware that can alter the boot process and is difficult to detect, as it loads before the operating system and other security measures. Bootkits can persist even after the operating system is reinstalled.
