Subject: Increase in Sub7 scans


Since February, I've been receiving tcp port scans for the default sub7 
port
(27374) at a rate of approximately 3-4 per day.  Starting on June 8th to
present, I've been receiving them at 9 times that rate.  

6/5/01 - 3 Scans
6/6/01 - 4 Scans
6/7/01 - 3 Scans
6/8/01 - 8 Scans
6/9/01 - 14 Scans
6/10/01 - 38 Scans
6/11/01 - 22 Scans

Any ideas on what could have sparked this increased scanning?  A new
utility?  A new vulnerability related to sub7?  New media publicity?

Thanks
