From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The scary thing about this is thinking about potential undetected backdoors similar to this existing in the wild. Hopefully the lessons learned from the xz backdoor will help us to prevent similar backdoors in the future.
I think we need focus on zero trust when it comes to upstream software
exactly, stop depending on esoteric libraries
It is fine to use them just know how they work and check the commit log.
That of course requires you to pull from got instead of a tarball
this was well hidden. not sure anyone would have spotted this by checking commit log
It was hidden in the Tarball
i'm not an expert, but my reading was that it was hidden in a binary used for testing EDIT: oh yeah, i see what you mean
