Nimda: W32.nimda.a.mm

“Awake, and rise to my defense! Contend for me, my God and Lord” Psalm 35:23

Looks like someone from 193.227.168.5 is trying to infect the server that hosts this site with the dreaded Nimda: W32.nimda.a.mm worm.

How do I know this? Well, one of the advantages of getting a real host is having access to real logs … like this:

  • 193.227.168.5 – - [25/May/2002:07:36:28 -0700] “GET / HTTP/1.1″ 200 16647

And because I’ve been hacked before, I now have some programs in place that wake me up on the middle of the night and tell me when such visits occur.

I could go on and on about how this particular worm works, but intead, I refer you to an excellent article by TruSecure, a company that provides solutions, as well as up-to-date news, for and about such problems.

Here are a couple of other interesting visits from 24.168.101.98 these are much closer to home … here’s just one set of prints we lifted:

  1. I’ve seen this in my logs as well. The two requests for cltreq.asp and owssvr.dll come interspersed with normal user page requests unlike nimda which comes from servers and is a stream of all nimda requests with no normal human page requests.

    It may be something to do with the user having configured IE to automatically check it the site has a forum. Is this true or not?
