   Of course we may not be out of the woods if the
following is true and used:

Sobig.F also opens the following ports:

    * 995/udp
    * 996/udp
    * 997/udp
    * 998/udp
    * 999/udp

And, it listens for any incoming UDP datagrams on these ports. Incoming
datagrams are parsed, and upon receiving a datagram with the proper
signature, the master server list of the worm may be updated.
...

That was from the Symantec site but is mentioned in other
places too.
