Microsoft’s Secure Boot has been broken for a decade and no one noticed until now
Builders and security-conscious users need to understand this deep system vulnerability when implementing secure infrastructure and need to assess their own device security.
AI Summary
Security researchers discovered a critical flaw in Microsoft's Secure Boot protection system that has existed for over a decade, allowing attackers to bypass the security feature using old, vulnerable 'shim' binaries that were never properly revoked. The vulnerability affects both Windows and Linux devices and enables malicious firmware installation that persists even after OS reinstallation. This reveals a fundamental failure in Microsoft's security certificate management process for boot-time protection mechanisms.
Excerpt
Old and forgotten "shims" Microsoft failed to revoke have made Secure Boot bypasses simple.
