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 Lee Fisher McAfee Security -----Original Message----- From: Charles Hamby [mailto:fixerat_private] Sent: 27 February 2003 18:25 To: incidentsat_private 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. -CDH 2003-2-23 23:05:52 Deny 213.51.247.114->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:49 Deny 213.51.247.114->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:36 Deny 213.51.21.143->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:33 Deny 213.51.21.143->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:30 Deny 12.242.204.86->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:27 Deny 12.242.204.86->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:23 Deny 62.253.118.133->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:21 Deny 65.163.177.202->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:20 Deny 62.253.118.133->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:19 Deny 217.1.167.84->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:18 Deny 65.163.177.202->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:18 Deny 12.231.241.129->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:18 Deny 24.66.39.214->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:17 Deny 12.229.115.40->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:16 Deny 62.190.172.203->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:16 Deny 217.1.167.84->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:16 Deny 217.162.202.177->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:16 Deny 217.162.183.155->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:15 Deny 12.231.241.129->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:15 Deny 24.66.39.214->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:14 Deny 141.153.232.196->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:14 Deny 12.229.115.40->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:14 Deny 12.231.161.15->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:13 Deny 217.162.7.16->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:13 Deny 62.190.172.203->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:13 Deny 12.242.250.247->W.X.Y.Z 0 sec TCP PORT 445 2003-2-23 23:05:13 Deny 217.162.202.177->W.X.Y.Z 0 sec TCP PORT 445 ---------------------------------------------------------------------------- <Pre>Lose another weekend managing your IDS?
