Researchers seize control of one of the world's largest spam-spewing botnets

Researchers seize control of one of the world's largest spam-spewing botnets, but there is disagreement about what should happen next.Researchers at TippingPoint Technologies' Digital Vaccine Laboratories have found a way to infiltrate and seize control of one of the world's largest spam-spewing botnets, a breakthrough that has ignited an intense debate over the ethics of "cleaning" infected computers.
Cody Pierce and Pedram Amini, two high-profile software security researchers, cracked into the Trojan powering Kraken—a 400,000-strong botnet of infected computers—by reverse-engineering the encryption routines and figuring out the communication structure between the botnet owner and the hijacked computers.
Once they got a clear understanding of the inner workings of Kraken, the duo found that the infected computers were trying to connect to a master C&C (command and control) server by systematically generating subdomains from various dynamic DNS (Domain Name System) resolver services.
This meant the researchers could predict where the bots would be connecting upon reboot, Pierce said in an interview. "We basically have the ability to create a fake Kraken server capable of overtaking a redirected zombie," Pierce said.
