A clickbot is a software robot that clicks on ads (issues HTTP requests for advertiser web pages) to help an attacker conduct click fraud. Some clickbots can be purchased, while others are malware that spread as such and are part of larger botnets. Malware-type clickbots can receive instructions from a botmas- ter server as to what ads to click, and how often and when to click them. There are many types of clickbots used on the Internet. Some are “for-sale” clickbots, while others are malware. For-sale clickbots such as the Lote Clicking Agent, I-Faker, FakeZilla, and Clickmaster can be purchased online. They typically use anonymous proxies to generate traffic with IP.
