markob17 on "[Plugin: Wordfence Security] Alerted that someone logged in successfully as "systemadmin" Did I get hacked?"

Hello,

I received this message an hour ago: An unknown location at IP 67.212.93.169 logged in successfully as "systemadmin".

I do not have an admin account on my Wordpress installation with that name. Did I just get hacked? I'm not sure what to do and am worried.

Thanks,

Mark
