Date: Wed, 17 Apr 2024 02:07:43 +0200 From: Vegard Nossum <vegard.nossum@...cle.com> To: oss-security@...ts.openwall.com Subject: Make your own backdoor: CFLAGS code injection, Makefile injection, pkg-config Hi all, Given the recent xz/sshd backdoor, I wanted to try to think more like an attacker and build my own backdoor. To start off, I've chosen the Linux kernel as the target for the attack, and I want to do it without changing either the kernel source code or any release tarballs.
