With the recent release of several known exploits in the phpBB2 forums software (the highlighting code exploit), as well as issues in PHP itself, I have seen a huge surge in the number of attempts at my site to gain unauthorized access; reaching nearly 5000 unique IP addresses being blocked on 8 January 2005. I'm sure that many other website administrators will notice the same trend. As such, I'm reminding everyone about the IP Address Blacklist available at NukedGallery.net (Downloads -> PHPNuke -> Misc Code). This is a file which is updated nightly with all the new addresses which have attempted to break into my servers, either via port 80, or other ports (see http://www.nukedgallery.net/modules.php?name=IPBan for a complete listing).
Registration is required, to prevent bandwidth leaching bots from pulling the files.
