May want to access your database and check the forum descriptions...Could be in there too...
Why is it that once a month my website gets hacked?
Have you checked your site for backdoors left by the hackers, extra admin acocunts in the database, unknown/unrecognized files on your website?
Is your host up to date on their security measures? Could be their getitng in from the host side. Are you on a shared hosting plan? They could be getting in from another board who has not updated thereby giving them access to everyones board, updated or not....
Too many variables to say they used phpbb to get to your site. Once a site/host is compromised, it can be a bugger to make it secure again.
