My vBulletin forum was also hacked via Symlink. My forum was on shared hosting server.
This tutorial article (
http://www.securitygeeks.net/2012/08...-tutorial.html ) shows how easy it is for hacker to hack into your vBulletin forum.
The hacker installed symlink plugin into my forum and use it to access other accounts configuration information in the shared server.
Now, I have a hard time to clean up the symlink plugin software and any files that were installed and modified by the hacker.
Anybody can help me or provide advice on how to clean up the software installed/modified by the hacker?
