please give me some advice on how to handle the illegal invasion into my pc (UBuntu20.04) ? I went back home and saw someone remotely accessing my pc browsing my documents, closing my browsers and viewing my conversation with other people in an app. I can't believe that this could happen so easily. But it did happen. I did not stop the hacker immediately when I saw that, instead I used my cellphone record that.

I don't know how the hacker got access to my pc remotely, could someone explain the typical way and talk about anti-hacking methods that I could use as an ordinary Ubuntu user.

Thank you very much.

  • Have you considered an encrypted installation? It is simple with 20.04. – C.S.Cameron Jul 24 '20 at 6:59

    Encrypted installations are useless if the attacker gets access to a running system. – Sebastian Jul 24 '20 at 16:48
  • How is VNC setup? Is it set to connect directly from anywhere in the Internet? Someone could guess your password (or use a dictionary attack) and remotely break in. See this answer for one solution also see this answer. – user68186 Nov 19 '20 at 21:14

There's no simple answer to this. It's most likely you've installed a virus / malicious software that's used to hack your computer .

Your best best it to wipe the system, scan for viruses & check what programs you've installed before to avoid repeating the same mistake .

I'd also check all attached devices & router settings to make sure the hacker didn't leave a backdoor into your network .

  • Thanks for the your answe. the pc is primarily used for research and programming. Thus most softwares I have installed are from sudo apt install. The only thing I think problematic is dash to panel which prevent the system from being locked. Other softwares are VNC , teamviewer. – Albert G Lieu Jul 24 '20 at 6:22

    VNC might be an issue if done incorrectly with easy passwords & open ports. Im no expert with VNC, but once the system is compromised, assume everything is compromised with backdoors everywhere, so act accordingly. GL – MichaelHabib Jul 24 '20 at 7:04
