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 theory, a virus can hide from them if it replaces (or LD_PRELOADs) them with something that filters the virus from its output.

those task viewers will show everything running, except some kernel modules, because they are part of the kernel.

also fast cron jobs will only be visible for a very short time. only while they run. if they run for like 250ms you probably won't notice them.
