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 people in my mastodon feed are suggesting that the backdoor might have connected out to malicious infrastructure or substituted its own SSH host keys, but I can't find any clear confirmation. More info as the investigation progresses.
I guess at this point if you're on Fedora 40 or rawhide clear / regen your host keys, even after xz version rollback
If you are on a affected system I would nuke from orbit.
Nuke from orbit might be an overreaction, if you need that machine perhaps disable ssh or turn the machine off until later next week when the postmortems happen. If you need that trusted machine now, then yes fresh install
Honestly doing a fresh install is a good test of your recovery abilities. You should always have a way to restore critical content in an emergency
I feel legitimately sorry for anyone who takes your rhetoric to heart.
Try not to let these 🧩's pull you down rabbit holes, guys.
