Yep. I still get a zillion hits a day trying to get into my SQL Server because of that stupid SQL-Worm gizmo that scans IP's searching for SQL Server databases that didn't get a password setup in them. http://www.eeye.com/html/Research/Tools/sqlworm.html and then the virus version explaination of it http://shop.osborne.com/osborne/virus_alert/voyager_alpha.shtml
I wonder how long it will be before the bandwidth on the net being used for scanning/hacking attempts will exceed that of the people actaully trying to do something productive.

>>It uses a text file of proxy servers and it's multi-threaded, so not only is the IP going to show it as coming from one of proxy servers, but it's also able to run like 150+ threads at a time (thus having 150+ anonymous proxy servers each scanning a range of target IP's at a time). Combine that with the ability to zombie and......well you get the idea.

Port 137 is used by Windows NetBIOS/SMB file service so if you're purposely or inadvertently exposing this service to the Internet you might want to be extra vigilant.
