Everything I Know About the Xz Backdoor
Please note: This is being updated in real time. The intent is to make sense of lots of simultaneous discoveries
Sounds like a concerted effort by a reasonably competent state actor. The +0800 timezone offset implies parts of Asia and is a small but crucial detail, esp given the commit times. In other words, China, Malaysia, Korea, etc. -- somewhere in Asia.
OTOH the author even concedes identity theft or smart attempts to discredit and point at Asia. Still, is on par for Chinese and NK actors.
33It could also be the opposite, someone trying to act like one of the Asian countries. The article lists the UTC times for the commits at 12-17, which would correspond to 8AM-1PM EST or 5-10AM PDT. That also could be fudged, or it could be a relatively new US spook working primarily in the mornings. Or if it's someone in Asia, that's 8PM-1AM, which is the perfect time for an evening hacker.
It's really not clear who's behind it.
I'm guessing an independent hacker in Asia because a state actor would probably just exploit existing bugs instead of adding new ones, and they certainly wouldn't do something as obvious as "safe_fprintf -> fprintf." I'm guessing this is all one individual trying to create business for themselves.
23In other words, China, Malaysia, Korea, etc. – somewhere in Asia.
The Shadow Broker's leaks showed that state actors had whole tool suites to ensure that the product appeared like it was coming from a different location. Given that those tools have been leaked since 2016 and the concept is even older; relying on metadata like timezones, character set, etc... to make determinations about location is unreliable at best.

What a wild read. Definitely smells like nation state actor.
22Timeframes of commits line up with afternoon/evening in Moscow.
4I'm not really convinced. I haven't seen anything outside the capabilities of a talented individual, and such an exploit would be worth a lot of money, so the motivation is there.

It's so disgusting to think that Jigar Kumar guy pressuring the original maintainer was Jia himself just manipulating his way into a maintainer role.
I hate people sometimes.
16It may not have a been a single person in the first place. “Jia” may have just been a front for multiple people or a team of people working together to facilitate the whole situation.

this is insane that it lasted as long as it was before found. I'm glad that was quickly resolved before it hit stable.
9And there's the Open Collective Foundation closing (not Open Source Collective or Open Collective Inc), which means a bunch of projects need to deal with a bunch of paperwork.
I wish FOSS had a better community backing so a larger group of trusted devs could handle maintenance on multiple projects. Basically, any "production" Linux distribution would only ship software with stable maintenance. I'd join such a group, but as always, funding is an issue.
