The xz package that has already entered the current F40 pre-release versions/variants and rawhide contains malicious code. This does NOT affect users of the Fedora releases (F38, F39 are thus not affected), but all users who use already F40 pre-release versions/variants or rawhide shall read this: Article: CVE details: https://access.redhat.com/security/cve/CVE-2024-3094 Be aware that this is CVE criticality 10: this is the highest risk factor. Also be aware that the header of the RH arti...
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 authenticationallows 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.
You mean thousands?
That was supposed to be or, not of.
Hard to tell from first glance but my guess would be this is fallout from the ongoing
