Well, most ISPs already have thin margins to work on. But yes, the larger providers should be contacted, especially when a major block of theirs is infected. > But I don't want to take the time to do it manually. Any > suggestions? I already saw someone mention DShield.ORG, which seems to be the most popular right now. On more corporate networks with ununsed IPs, I like to use various port fakers that accept a SYN, but don't accept their ACK. That keeps the zombies tied up and busy, expoentially reducing the number of hosts they can attack. -- Bryan J. Smith mailto:b.j.smith@xxxxxxxx Sent from Yahoo Mail (please excuse any missing headers)
