Yesterday I noticed that the xterm title I use changed suddenly to something strange.So I suspect that someone hacked my Linux laptop (I'm using Arch).I changed the WiFi parameters (pass, essid) and changed my password on the computer.I also reinstalled all packages to overwrite files that may have been changed.I tried to take a look at the changed files, logs and so on, but I don't have experience in security, so it was like walking in the dark ;) and of course I didn't found any signs of intrusion.Do you think I should wipe the system and install from scratch?
Do I need to wipe and reinstall after possible hacker attack
