My site is www.ClanFromUncle.com
and the systemdoctor part is nothing to do with me. It seems that my site is mentioned in the script for some sort of tracking purposes.
I am not really trying to say the hack was the fault of phpbb, more saying has anyone got any ideas how it happened. I have spoken to my web host and kind of got a poor response.
I quote their reply "I am sorry to hear that your forum has been compromised.
We recomend that you run a security audit on your forum, and contact the developers to check for any security patches or updates.
In our experience, these type of compromises are usually as a result of exploitable scripting issues, or permission issues."
