I had a user log on to my remote access VPN, the users machine was
doing TCP-sweeps on port 445 and I think it may have been infected
with MS Blaster. Does anyone have a suggestion on how I can detect
this type of traffic with Snort. I am thinking of writing a sig that
looks for port 445 traffic and setting a very high threshold, it would
be nice to to re-invent the wheel though. Thanks in advance.
