A good friend of mine says that the biggest threat to computer security is the man, the user. And he has no other reason. We always talk about viruses and computer security, how very difficult it is to break into a system GNU / Linux and very easy to get into Windows. But difficult does not mean impossible and more and more threats are created for GNU / Linux and especially for Ubuntu, Being one of the most used systems within the family GNU / Linux. the rootkits are a good example of a threat that has been reached UbuntuWhile just as there is a way to get it out, there is always a way to get it out of our system.
What is a rootkit?
seconds the wikipedia a rootkit is 1 program that allows continuous privileged access to a computer but keeps its presence actively hidden from the control of administrators by corrupting the normal operation of operating system or other applications.
It is a dangerous threat for Ubuntu users as the first thing that can be done is to change the user and / or administrator password and disable our system.
Chkrootkit, a solution
Canonical, perhaps aware of these threats, has arranged in its repositories a program that corrects or warns us of possible rootkits that live in our system. The application is inherited from Debian but equally available and functional as in the parent distribution.
To install it all we have to do is go to our terminal or synaptic and type
sudo apt-get install chkrootkit
This will install the program, the only downside is that it does not have a graphical interface so every time you want to use it you will have to go to the terminal and type
This will run the scan and let you know if your computer is infected or not. If you become infected, all you have to do is search Google for rootkit and its solution as it is very difficult for a program to fix them for you rootkits, Either in Windows, Mac or Ubuntu.
Oh, one last recommendation. chkrootkit is a program that only works if we run it, it does not work like a classic antivirus that is always latent looking for viruses or threats, nor will it take precautions for ourselves, so I recommend that from time to time, once a week for example, pass this tool through your system as well as the antivirus through yours pendrives. You never know where the danger may be.
