imagine a worm if you will, spreading through iis, netbios, sql, exchange, .asp pages, samba, aim file exploit, and a false ms update, the purpose, only to wait until a certain time to start randomly pinging every host on the internet. Seem impossible? Right now there are over 100,000 bots that i have seen, many more which i have not, or are not public, most of which compromised by the methods ive said. 100,000 machines sending an average of 1000k/sec (average from oc-3 to dsl/cable), would create a mass flood of 1000MB/s, as servers stall, more drop, and the internet becomes a standstill. Think my figures are exagerated? I dont beleive so, seeing how many fast servers/iis/exchange have been compromised, this massive DDoS could drop the internet.
