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?
In general, no. Most malware that runs its own process simply uses some name intended to make you not notice it. But it is possible, in Linux just as in every other operating system that ever existed, to imagine that some unusually sophisticated malware manages to exploit some unknown vulnerability to gain full control of the kernel and then all bets are off, then it would be able to do anything.
