Forgotten UEFI shims undermining Secure Boot
ESET researchers identified 11 UEFI shim bootloaders signed by Microsoft that contain vulnerabilities allowing attackers to circumvent UEFI Secure Boot protections. These bootloaders, some containing exploitable flaws from over a decade ago, remain in circulation despite their security risks.
Why it matters: System administrators and firmware vendors need to audit and revoke trust in outdated UEFI shims to prevent attackers from using them to load malicious code during system boot, bypassing a key security boundary.
