today i found strange high cpu load and based on top -c showing that i have 2 ./system-disk processes that eat about @50% and run in long time, the process is under an user and i have scanned the account related i didn't see any malicious activity
now i have killed the processes

what is ./system-disk processes actually?

Hello,

You can search for files matching that process name to see if anything shows up so you can get a better idea of where the file exists and what it does. EX:

Code:
find / -name "system-disk"
You may also find the following thread helpful:

Thank you.

Run 'ps faux' to get a little more info, or take the PID from top and look for it in 'ps faux' output.

This should get you user id if nothing else. You can also use the PID to gather other information.

I am guessing this is a spoofed process name from perl script, you may not find any file called system-disk (or you might, too, but you'll have to look.)
