What is click network?
A click network refers to an agreement whereby cyber criminals have computer networks click through online ads to increase their revenue from advertisers. A click network can consist of people running a network of computers that are programmed to click certain web sites at specific intervals. However, infected computers that are part of a botnet have also been used to perpetrate this type of click fraud.
Hackers with large numbers of computers unknowingly tied into a botnet can rent them out to criminal organizations to carry out click fraud. The cybercriminal creates a skeleton site, usually with nothing but advertisements, and then the botnet PCs click away. Although a certain percentage of the revenue generated is likely to be recorded as click fraud rather than paid clicks, the scammers can persist the fraud for longer by rotating the clicks on the botnet through different groups of skeletonized websites.
