Researchers have identified a new botnet based in China that was openly selling DDoS-for-hire services and had managed to plant roots inside a number of major U.S. ISPs. The botnet, known as IMDDOS, is mostly contained right now and the researchers are working with authorities to locate its operators. Most of the infections appear to be in mainland China and the main Chinese domain associated with the botnet has a list of other domains that can be leased out to customers. Damballa officials said the operation appeared to be quite professional, and went so far as to include a dedicated sales team.
