Note: I have already posted this to ubuntu forums but I have not received an answer. I was given advice that information security is a better place for such a topic even if it's ubuntu-related
I'm kinda new to ubuntu but I have switched to it from Windows since I have heard that it's more secure and more virus-free. In the last few months, I have read a lot about computer viruses and it probably made me a bit more paranoid.
What are the chances of getting a Remote Access Trojan (RAT)? I have noticed several times that when I left my room for a while another window/program I did not touch was opened and since my computer contains a lot of source codes, I would consider it as 'end-of-my-life' if I was infected.
I have uninstalled VNC (vino) from my machine right after the system installation
I have not download anything unknown from the internet, only a few well-known programs using official packages with
I have not visited any websites I would not be sure about (my ubuntu is only used for programming)
I use ClamAV scanning tool every morning
clamscan -r --bell -i /
Solutions I have already heard about but I have not really tested them
wiresharkto monitor traffic (I am not experienced with using this tool I would like to know what kind of data should I be looking for)
- I have also heard that
iptablesmight be useful
I know that you can never be 100% sure that your computer is virus free, but I think having a RAT in your computer is kind of 'extreme virus'. To be honest, I doubt that someone would really be controlling my PC since I am sure there is no real way for him to do it, but on the other hand I'm still paranoid about this. Is there any way I can really check it and then finally close this case which eats a lot of my time searching security forums etc... ?
