It was mentioned that this was a co-ordinated attack. That meant a bit of planning and access to various machines. As to the number of attackers only Yahoo's internal people may know. Even then it may have only been one individual with a script that accessed many locations at one time and initiated the commands. There is the ability to do such an attack.

It's an interesting coincidence that, at roughly the same time that the attack was taking place, we were sitting in the NANOG meeting listening to a presentation on Distributed Denial of Service attacks. It's definitely a major threat... -rb ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
