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.

or substituted its own SSH host keys,

why would the backdoor do that? It would immediately expose itself because every ssh client on the planet warns about changed host keys when connecting.

Perhaps it was a poorly worded way of suggesting that invalidating host keys would invalidate all client keys it could potentially generate? Either way it's a lot of speculation.

Resetting the keys and SSH config on any potentially compromised host is probably not a terrible idea
