That would be awesome...Banky?
Nah, it would be difficult.
First, this is a pretty standard hack and they most likely do several of these a day making some decent money from their little extortion deal. IN case anyone was wondering, these open source mesage boards are filled with security holes that must be covered up.
Second, the site they posted is soemthing that is not worth hacking, so really no reason to. If anyone actaully wants to venture to it, do so at your own risk.
Third, there is a 99% chance they are from Eastern Europe or Asia and my guess would be Russia. Even if we want to hack them, it would be difficult to find them and if we did there would be about 30 others who would retaliate.
