Can you give me any information about which multicast group addresses

I didn't have any logging turned on at the time so I don't have the
addresses laying around. I just remember I had a storm of traffic trying
to go to addresses between 224.x.x.x and 247.x.x.x - the addresses looked
fairly random though. It may have been just a result of whatever random
address algorithm was being used. Since I don't route multicast, it stayed
local to the network segment but every host on the segment saw the
traffic.

I have seen very little sign of this worm in interdomain multicast; it
does not seem
to be causing MSDP havoc the way that the RAMEN worm did.

This one seemed to be particularly nasty as it was generating traffic to
multicast addresses too. It caused a nice flood on the switched ethernet
segment I had a vulnerable box on.  (And took out a router in the
process.
Great fun.)
