Security Incidents: RE: TCP 445 Scan?

[Lee_Fisher () NAI com]

I have seen a few forums discuss an increase in TCP port 445 scans.

Similar nature/profile to your message below.

LANMAN service listens on this port.

This *may* be related ?  http://www.kb.cert.org/vuls/id/693099

Subject: TCP 445 Scan?




Morning/Afternoon All,

Has anyone else recently been pegged with a large number of distributed 
TCP 445 scans over a short amount of time (within a few minutes)?  A 
couple of days ago I was hit by roughly 60+ scans in a short amount of 
time; when I waded through it it wound up being about 45 unique IP address 
all looking for TCP 445.  Below is an excerpt from my fireall log 
(Netscreen).  Has anyone else been seeing these sorts of scans lately?  
I've only seen the one scan, so I haven't had a chance to capture any more 
traffic.
