That particular host also was apparent in analyses of the QAZ trojan - http://www.sans.org/infosecFAQ/malicious/QAZ3.htm I would assume it's been long since disconnected from the network it was a part of. Could this worm have re-used code or is the writer that out of touch with reality? Paul ----- Original Message ----- From: "John Q.

here I go replying to myself again... we cannot get it to send mail to a dummy host we have built. It connects and sits there. if nimda is waiting for a particular response, it's not obvious in the strings of the binary. (and not obvious to someone who fears assembly) one interesting point, however, the infected host immediately began
sending
out arp requests to the /24 broadcast one at a time, about 3 seconds
between
each request, from 1 all the way up. it was keen enough to ignore itself. perhaps we'll set up some virtual interfaces on the gateway we've built
and
see what it's trying to do. .nhoJ On Tue, 18 Sep 2001, John Q. Public wrote: |always to the same IP: 202.106.185.107 | |sorry if it's been posted, but I haven't seen anything about that
