Yeah, there was an announcement about the security issue - sadly after we had been hacked. The rest of the internet then decided to post up step-by-step instructions on how to hack any vBulletin forum (that still had missed the announcement/hadn't gotten an email from the team) so they all rushed to the party.
Helpful, news sites, very helpful.
But point is as you say Uatec they weren't skilled or talented people. They did it just because they could. Sadly.
