The well-known web forum software vBulletin has notified its members and customers that it has been breached. With the breach, hackers were able to obtain usernames and encrypted passwords. The warning email and the company's forum post state that administrators have revoked all passwords and are urging their customers to change them. See the email we received
The software is known for security vulnerabilities that have been discovered for a long time and its developers are unable to fix.
If you have a vBulletin and use the same password elsewhere, it would be a good idea to change it immediately. It is probably unnecessary to recommend that you change software if you are the administrator of a forum running vBulletin.
