One of my sites got hacked back in 2006 by a similar sounding hacker - at the time i think i was running 7.2.2 and originally thought that my SSH account had been compromised. As it turned out it was a php/mysql exploit.
I upgraded to the latest ubb version that was available, and have kept up to date with the versioning since and (touch-wood) have not had any similar experiences since.
