Timeline of the xz attack

not exactly fun but more :poop:


“Over a period of over two years, an attacker using the name “Jia Tan” worked as a diligent, effective contributor to the xz compression library, eventually being granted commit access and maintainership. Using that access, they installed a very subtle, carefully hidden backdoor into liblzma, a part of xz that also happens to be a dependency of OpenSSH sshd on Debian, Ubuntu, and Fedora, and other systemd-based Linux systems that patched sshd to link libsystemd.”
