When the Linux Foundation announced that it was creating its own UEFI boot solution, it seemed that our woes about not being able to install Linux on Secure Boot systems would soon be coming to an end ...

A critical vulnerability in the Shim Linux bootloader enables attackers to execute code and take control of a target system before the kernel is loaded, bypassing existing security mechanisms. Shim is ...

Pressing the backspace key 28 times can bypass the Grub2 bootloader’s password protection and allow a hacker to install malware on a locked-down Linux system. GRUB, which stands for the Grand Unified ...

Bootloaders are an essential bit of software for almost every modern electronic device. Unfortunately, any vulnerabilities in the bootloader can open a device up to attackers. Eclypsium researchers ...

There is a gaping security hole in the open-source bootloader shim that allows attackers – to inject their code in a man-in-the-middle position –, for example. A complete compromise of the systems is ...
