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.

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?

Depends on the malware.

With total access, nothing would prevent the malicious code from modifying the task viewer itself to make it ignore the resources it is using.

Accounting for every way malware might be discovered is difficult, but with enough system access, it's all possible.

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
