  • My vB forums were hacked by THIS vB user:

    Two days ago, I found that my vBulletin v3.5.2 forums had been hacked (help request posted here). Some manner of vulnerability was exploited such that the malicious user inserted HTML redirects into the forum titles of the FORUMS table in the DB. As soon as a user hit my forums, they were redirected to this page:

    http://www.enyenimix.com/hacked.html

    As you can see, the malicious user's handle is "EmRe_DaNCeR". My forums were down from early afternoon to the wee hours of the next day, when I finally got the system updated to vB v3.6.5. (I hope this exploit was addressed between 3.5.2 and current!)

    I just did a WHOIS lookup on the "hacked" website people were redirected to. Look what I found:

    Code:

    The registrant's name is Emre! It seems this guy redirrected folks, in the hack, to his own website! I looked at the source of the "hacked" page and found the image and MP3 were being loaded from blueforumum.com. So I went there and found a user named "EnYeniMix.CoM". He is an admin, user id=1.

    Here is the WHOIS on blueforumum.com:

    I thought people in the vBulletin community might like to know about this. I might also request that Emre Koseoglu not be granted any further vBulletin licenses - that is, if he even has a valid license.

    Do with this information what you will.

    Its not really considered an exploit of such, because it requires an authinicated administrator and we do permit html to be entered into forum titles and descriptions. In the future you need to be much more carful about who you are giving login information to.

      I am the only administrator. I have two users with admin access - both are mine. I've given the info to no one.

      I have two moderators, but they've pretty much got default access. It's not possible for a moderator to have such access (if not an Administrator), is it?

      Also - nothing in the Admin logs as viewed through the CP that shows any forum alteration action connected with this - nothing.

      Is this, then, a new exploit? Tnx.

          I have upgraded to 3.6.5.

          I had been hoping this closed the exploit used here, but Zachery feels this is not an exploit at all, though the lack of evidence in the CP log would seem to indicate otherwise... ?

            If your account has log pruning rights, maybe it was compromised and then the logs were just deleted. Otherwise, it would have to be some kind of compromise of FTP or shell access, or similar. Make sure that all of your passwords are secure and not the same as you use at other sites.

              From experience, very few people who claim to be hacked through vBulletin actually are. Most come down to direct database access, FTP access or root access on the server.

              What he said is we allow HTML to be used in the forum titles and descriptions and that these are not exploits. If there is no entry into the Control Panel Log, it means one of two things happened:
              1) The attacker deleted the logs which means he had access to an administrator account with full access to the control panel (i.e. a Super Administrator)
              2) He had direct access to the database and could circumvent vBulletin's logging features.

              Honestly, I recommend the following:

              Change all your passwords for email, FTP, database and vBulletin's Control Panel. They should all be different and at least 12 characters with a combination of upper and lowercase letters, numbers and punctuation.

              Do not access your site through FTP but use SFTP instead. Some hosts require shell access for this so contact your host. If they don't give it then move to a more secure host.

              Rename your admincp and modcp directories. While this isn't really security, it can deter some people. Especially if you make the directory names obscure enough.

              Place .htaccess on your admin and moderator control panel directories as well as your include and install directories.

              Since you're the only administrator, delete the secondary administrator. There is no point in having it and it only makes your site less secure by opening another vector of attack.

                Thanks.

                The logs are present, just no entries that show any change to forum info. Can a super admin delete selective entries in the logs? Tnx.

                  You can prune log entries based on the script, the user that created and how old they are.

                    There are no unusual IPs in the Control Panel logs and there are previous entries (forum initial setup) of forum.php script.

                    Does that not rule out pruning here? I think this is a new exploit.

                      When you prune admin logins, it prunes them, theres no log of them being pruned. Either this user had direct access to the admincp or the database.

                        The Apache logs show all accesses to 'forum.php' to be my access AFTER the hacking of my forums took place. So they could not have had AdminCP access, based on this, it seems.
