Windows and Linux users: The deadline to update Secure Boot keys is near
Three Microsoft-signed certificates used in Secure Boot, the chain of trust mechanism that verifies firmware and software during system startup, will expire on June 24. These certificates are critical for preventing UEFI bootkits, which are firmware-based malware that loads before operating systems and can persist across OS reinstallations. Windows and Linux users need to update their systems to obtain new keys before the deadline to maintain boot security protections.
Why it matters: Organizations should prioritize updating Secure Boot keys before June 24 to prevent systems from potentially booting unsigned or malicious firmware after certificate expiration.
