Yes. It was interesting. My understanding is that what I am about to tell you is old news, but here: Attacker sends a packet with a source address of the victim, with a dest address to the broadcast of a (pick any) network. Every machine on the network will then respond with a ICMP reply to the 'source' (the victim). My understanding is that a 28.8 users could easily fill a T1 (or more) with this method. We have no proof, but someone did this to us from what appears to be a ISDN account from PSI, and filled 6 - 7 mb/s of our Ethernet genuity connection in doing so. It was *not* cool.
