Early this morning CodingForums was hacked, specifically, the vBulletin software. The hacker added himself as an admin user, and carried out a few tasks such as email all forum members letting them know about it. The user gained entry through a vulnerability in vBulletin, as we weren't using the latest version.
I've been working with our host and believe everything should be back to normal now. The way member passwords are stored, the hacker should not have access to them. FYI having access to an account is different than knowing its password, due to the way vBulletin stores the passwords. Better safe than sorry however, so I urge everyone to go into the USER CP and change their password.
Usually I'm very cautious when it comes to security, but this time laziness got the best of me as I left the vBulletin software unpatched for a while. Sorry about the downtime, and let me know if you experience any problems.
