That will work short term. Once you have your network Clean do not forget to take that pointer out so that Windows update will work so when Bill's next security hole is released you can update your PCs via this Wonderful feature.

The worm does a lookup on windowsupdate.com so if you put in a record on your dns servers to point to, say, 127.0.0.1 you can redirect the attack to target the host computer loopback instead of taking out your network bandwidth.

Subject: rpc dcom worm and windowsupdate

Hey guys,

Ok our company is owned by the msblaster worm, now we would like to keep the ddos attack under control. Our Idea is, that we can make that one of our proxies will identify himself as windowsupdate.com.

Now my question is, is the Worm looking for windowsupdate.com per Lookup or has it a fix ip in the Source ? Does someone know anything ? Haves some the sorce :)

PS:
What are you doing against it ?

regards

Gruskovnjak Oliver
