Kobalos malware - possibly ported to Linux

Hello:

Just a heads up so we're all on our toes:

This morning's article in The Register:
https://www.theregister.com/2021/02/03/kobalos_malware/

ESET page on the matter:

We reverse engineered this small, yet complex, malware that is portable to many operating systems including Linux, BSD, Solaris, and possibly AIX and Windows.

Best,

A.

Thanks for the heads up.

From this article it says...

https://insidehpc.com/2021/02/report-se … x-malware/

To reduce the Kobalos threat, ESET suggested implementing a two-factor authentication for connecting to SSH servers because “stolen credentials seems to be one of the ways it is able to propagate to different systems.”

To remove the risk completely:

# apt purge openssh-{client,server}

Be nice to see libressl ported to devuan/debian as in maintained by devuan/debian. If i was smart enough i would give it a try. Not that it matters with this type of malware i dont suppose.
