Port 4444 hits...

["Chuck Lewis" <clewis@xxxxxxxxxx>]

Hi folks,

 

Long story but we got HAMMERED by Nachi last week. Timing is EVERYTHING.
Have two firewalls and one had Port 135 blocked. Well it was getting
"rearranged" on the network by some folks and in that brief/VERY brief move,
in comes Nachi. So it hits 10 sites. We put ACL's (Access Control Lists) on
the routers so "nothing gets in and nothing gets out" on specific ports so
it is contained as I work through cleaning it up. I was putting fixes on for
Nachi, SoBig and Blaster.

 

Started here and thought I had it licked. No port 135 stuff showing against
the ACL. But in a little while port 4444: ACL = deny tcp any any eq 4444
(282 matches) starts logging. And that seems to be Blaster.

 

So I have downloaded Netasyst (Sniffer) from NAI, already had Network Probe,
etc. but I'm too "stupid" to use them.

 

Any one have any experience with this stuff ?

 

Thanks,

 

Chuck
