From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Viruses & Task Viewers (lemmy.world)

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.
