'Bootkitty' First Bootloader to Take Aim at Linux

Researchers discovered 'Bootkitty,' a proof-of-concept UEFI bootkit for Linux that uses a LogoFAIL image-parsing exploit (CVE-2023-40238) to bypass Secure Boot, modify GRUB signature verification in memory, and preload ELF binaries; analyses by ESET and Binarly indicate it is functional but appears limited in scope and likely created by students for awareness rather than active campaign dissemination.
