Cybersecurity researchers have discovered 11 old, Microsoft-signed, Unified Extensible Firmware Interface (UEFI) applications that could be abused to bypass Secure Boot on most systems using the modern firmware standard
Although it hasn't been seen in the wild yet A new ransomware strain dubbed HybridPetya was able to exploit a patched vulnerability to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot on unrevoked Windows systems, making it the fourth publicly known bootkit capable of punching through the feature and hijacking a PC before the operating system loads.…
Cybersecurity researchers have uncovered multiple security flaws in Dell's ControlVault3 firmware and its associated Windows APIs that could have been abused by attackers to bypass Windows login, extract cryptographic keys, as well as maintain access even after a fresh operating system install by deploying undetectable malicious implants into the firmware
ControlVault3 firmware vulnerabilities impacting over 100 Dell laptop models can allow attackers to bypass Windows login and install malware that persists across system reinstalls. [...]
Details have emerged about a now-patched security vulnerability that could allow a bypass of the Secure Boot mechanism in Unified Extensible Firmware Interface (UEFI) systems
Microsoft has disabled a fix for a BitLocker security feature bypass vulnerability due to firmware incompatibility issues that were causing patched Windows devices to go into BitLocker recovery mode. [...]
The myth 'is now a reality' BlackLotus, a UEFI bootkit that's sold on hacking forums for about $5,000, can now bypass Secure Boot, making it the first known malware to run on Windows systems even with the firmware security feature enabled.…
A stealthy Unified Extensible Firmware Interface (UEFI) bootkit called BlackLotus has become the first publicly known malware capable of bypassing Secure Boot, making it a potent threat in the cyber landscape
A security feature bypass vulnerability has been uncovered in three signed third-party Unified Extensible Firmware Interface (UEFI) boot loaders that allow bypass of the UEFI Secure Boot feature
Some signed third-party bootloaders for the Unified Extensible Firmware Interface (UEFI) used by Windows could allow attackers to execute unauthorized code in an early stage of the boot process, before the operating system loads. [...]
