Hello everybody! I can say I’m a newbie at Linux. Wanted to ask about Linux’ task viewers. On the famous task viewers such as bpytop, htop etc., can viruses hide from them? Excluding the injected codes, can virus & tracker/logger softwares hide from classic task viewers of Linux? Do they show all kinds of services and running tasks?

  • It also depends on the viewer. I remember using prctl() in C to chamge a process name and top showed my change but htop didn’t. I’m sure a competent malware writer would be able to trick it though

      iirc, postgresql renames itself in htop to show its current status and which database it’s operating on
