You may have noticed that the forum was very slow earlier or, like me, you may not have been able to connect to it at all. That is because the forum was undergoing a brute force attack. A brute force attack is when automated methods are used to attempt to obtain the user password for the administrative account of the forum, using a trial and error algorithm that generates a large number of consecutive guesses. Since many people use words that they can remember as passwords, brute force attacks often begin by trying all of the words in the dictionary, rapidly, using multiple connections, or simply try commonly-used passwords or combinations of letters and numbers. In this case, they were all from Chinese IPs. They didn't get in, and I don't think they will get in, but they put quite a drain on the resources of the server, causing a slowdown that resulted in timeouts for some of us. In forums, brute force attacks are usually aimed at the Admin account but they do sometimes target other user accounts as well, so it's good to have complex passwords. Things seem to have calmed down now, however.
