In it, Google’s Click Quality and Security Teams highlight the activities of a botnet-based click fraud operator named Clickbot.A.
Clickbot.A is an example of a botnet operator attempting a click fraud attack against syndicated search engines. Google was able to identify clicks on our advertisers’ ads that exhibited Clickbot.A-like patterns and flagged them as invalid. While Clickbot.A is a specific example of a botnet application that conducted click fraud, botnets can also be used for keylogging, distributed denial of service (DDoS), and other types of attacks.
