I am 100% certain my machine was hacked. I am running Ubuntu 12.04 and had skype open (no connection with anyone) and Firefox, gmail and gchat in the firefox window and someone started type commands in my window and in my chat with a friend on my gchat account. They even typed an obscenity in my chat window!
I opened a command window pressing Alt CTRL T to try and reboot real fast because when i tried to move the mouse to restart he or she kept moving it away. In the terminal window the person kept trying to type this in: punapmep p-a
I just rebooted my machine. Is there anything I should do right now? Reformatting is not an option at this moment because I am traveling right now and I need a computer to check email consistently. How can I find out where the security breach is and how can I stop it right now?
Eventually I just pressed the power button to turn it off and rebooted.
Any advice on what I can or should do?
