My system was hacked last night, I was shut down from 10 pm until about 9 this morning, when I rebooted I had a new account called pbadmin on my login screen, before I just blow this acount away I would like to find out how he got into my system. Any suggestions on how to back track him? I'm running caldera 2.4edesktop, with a dsl connection through a cisco 675 and a netgear RT311 router.
