Security companies work together to take down botnet

While the internet security world is full of competition, a group of security experts and companies came together to help shut down the second version of the Kelihos botnet, apparently a much bigger version than the one that surfaced and was shut down in September 2011.

"The Kelihos botnet, also known as Hlux, is considered the successor of the Waledac and Storm botnets," Computerworld said of the botnet. "Like its predecessors, it has a peer-to-peer-like architecture and was primarily used for spam and launching DDoS (distributed denial-of-service) attacks."

The security experts analyzed and researched this new botnet for months and launched an operation for a takedown. In order to take it down, the company set up rogue clients around the world, which is known as sinkholing. Once the botnet clients were connected to the sinkhole server, they were able to see how big it is and take it down. This new botnet was said to have 110,000 infected computers compared to September's botnet, which had 40,000 infected.

Users should be aware of botnets and viruses that are looking to take any computer it can to become more powerful. People should have high-grade internet security and antivirus software to help stay clean of these botnets.
