You were able to talk to the person who hacked your forum...? That doesn't make any sense, but okay, let's roll with it.

vB is pretty secure, so anything such as whole or other flaws found would be on vB's website and probably have code patches to fix it.

When it comes to someone "hacking" into your site, it may not be the forum at all, it could be other scripts you have made, or the login to your control panel itself.

You should take these into account first, because most likely it is not vB.
