Viruses & Task Viewers
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.
Getting the sudo password is pretty trivial.
Just alias the sudo command to catch it and pipe it to the wanted tool.
With the sudo password you can recompile the kernel and add a random kernel module to it.
Only secureboot and verified boot make problems there. These are actually useful!
Good point, but seems like a non starter from many opinions on Linux forums.
I understand caution when approaching things like secure boot - it can absolutely be abused by monopolies. however... barring inherent or implementation flaws and ensuring that signing keys are under user control it conceptually (and practically) allows for some useful things.
Heads Firmware
Novacustom will support it soon!
Very true. Thanks for your answers!
