What is the name of the software that is affected??

xz is the compromised package, but it in turn compromises ssh authentication

In turn it ~~compromises ssh authentication~~ allows remote code execution via system(); if the connecting SSH certificate contains the backdoor key. No user account required. Nothing logged anywhere you'd expect. Full root code execution.

There is also a killswitch hard-coded into it, so it doesn't affect machines of whatever state actor developed it.

It's pretty clear this is a state actor, targeting a dependency of one of the most widely used system control software on Linux systems. There are likely tens or hundreds of other actors doing the exact same thing. This one was detected purely by chance, as it wasn't even in the code for ssh.

If people ever wonder how cyber warfare could potentially cause a massive blackout and communications system interruption - this is how.

tens of hundreds

You mean thousands?

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.
