They approach their task in a geometric manner. By the use of owned hosts to find other owned hosts. Potential Solutions Shore up the networks 1.

In this instance we find people weathering the packet storms and basically remaining disconnected from the internet for their duration.
Denial of service continues.
Fix the compromised machines 2. The number of owner machines is reduced as the result of better security practices. This is unlikely as many of the owned machines are not aware of the problem. The nature of the computer technology invloved means that new exploits will continus to be found. The polymorphic natuer of these tools makes them difficult to decect.
