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.

From that post, commits set to UTC+0800 and activity between UTC 12-17 indicate that the programmer wasn't operating from California but from another country starting with C. The name is also another hint.
That could be part of their plan though... Make people think they're from China when in reality they're a state-sponsored actor from a different country. Hard to tell at this point. The scary thing is they got very close to sneaking this malware in undetected.
A lot of critical projects are only maintained by one person who may end up burning out, so I'm surprised we haven't seen more attacks like this. Gain the trust of the maintainer (maybe fix some bugs, reply to some mailing-list posts, etc), take over maintenance, and slowly add some malware one small piece at a time, interspersed with enough legit commits that you become one of the top contributors (and thus people start implicitly trusting you).
Edit: Based on this analysis, they may have been based in a European timezone and just changed their timezone to UTC+8 before committing to Git to make it look like they were in China: https://rheaeve.substack.com/p/xz-backdoor-times-damned-times-and. Their commits were usually between 9 am and 6 pm Eastern European Time, and there are a few commits where the timezone was set to UTC+2 instead of UTC+8.
Except China is one of the countries involved in cyber warfare
Pretty much every country is engaged in cyber warfare to some degree
It is kind of sad
That's what states, militaries and other competition-infected minds do. Usually they say they imagine this to protect from it, then it becomes a weapon and "oops all wars"
I hate to be the bringer of bad news for you but everyone is "completion minded" as you say. That's how the world works
No that's a poisonous ideology that maskerades as normal.
No, it simply isn't. And even if it were true, there are people like me, who will gladly only be competitive in games and sports.
