Any recent hacked accounts from Southperry users?

I honestly thought that most people complaining about getting hacked were just careless or fooled by social engineering, until today, when I saw my bishop sign on while I was on my sniper. This is going to sound cliche, but I never gave my information to anyone, nor do I go to any sites except for SP and SW.

The weird thing is the hacker was on my account for literally 1 minute, and didn't take anything. I changed my password on both of my accounts, and moved all my equips to a friend just in case, but believe me, since I was extremely skeptical before, something weird is going on.

I'm going to reformat my computer just to make sure, even though my virus scan didn't pick up anything.
