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.

Some no-name came and without any problems asked to become a maintainer in a project used in almost any distro, took it over, put a backdoor in there and no one had any questions? In this case, everything turned out thanks to pure chance. Noname screwed up his backdoor, which attracted the attention of a guy from Microsoft, and out of boredom, he dug up what was what. And if I hadn’t messed up, or that guy from Microsoft decided to go drink beer instead of poking around in the xz code, then no one would have discovered anything. It’s scary to imagine how many of these nonames are sitting in all these thousands of open source projects, waiting in the wings to roll out a malicious patch.
