Our assessment of worm's behavior is below: If windowsupdate.com fails to resolve, it will return a -1, which is not interpreted because this routine has no error checking. The worm then attempts to send its SYN packets to 255.255.255.255, which may have done some interesting things, but it looks like the Windows raw socket implementation won't let that packet out. So basically, nothing happens. There might be some issues with cached DNS, but besides that it looks like the majority of the infections won't be doing much of anything besides eating CPU cycles on the infected hosts.
