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.

Damn, it is actually scary that they managed to pull this off. The backdoor came from the second-largest contributor to xz too, not some random drive-by.
They've been contributing to xz for two years, and commited various "test" binary files.
It's looking more like a long game to compromise an upstream.
Either that or the attacker was very good at choosing their puppet…
Well the account is focused on one particular project which makes sense if you expect to get burned at some point and don't want all your other exploits to be detected. It looks like there was a second sock puppet account involved in the original attack vector support code.
We should certainly audit other projects for similar changes from other psudoanonymous accounts.
Yeah, and the 700 commits should be reverted… just in case we missed something.
That is a should be standard procedure
Time to audit all their contributions although it looks like they mostly contribute to xz. I guess we'll have to wait for comments from the rest of the team or if the whole org needs to be considered comprimised.
It would be nice if we could press formal charges
Assuming that it's just that person, that it's their actual name and that they're in the US...
Do you have a source for this?
Source: they made it up
I don't have a source but I think it is safe to say given the large corporations and government institutions that rely on XZ utils. I'm sure Microsoft, Amazon, redhat ect are in talks with the federal government about this
