We have had 3 sites that were all hacked within the last 2 sites. No other sites are effected. All 3 of these were running some version of vBulletin. We did restore the sites from backup, and within hours they were hacked again. We can find no point of entry directly to the server. These 3 sites are the only ones running vBulletin at this time. I can find no mention of any security issues with vBulletin, but it's the only common link for all 3 sites. Anyone run into this before? Should be stop allowing vBulletin scripts all together..?
