Malware, for all the crazy things they do, exist because their creators want them to. Malware can be the product of a bored mind, of an experiment, of inspiration, or, as it is becoming increasingly common nowadays, as a means for profit.
No one bothers to create a botnet as complicated as KOOBFACE just for fun, so the question that begs for an answer is, “What is KOOBFACE for?”
In the third (and hopefully last) installment of our KOOBFACE research papers, we examined the various mechanisms KOOBFACE employed to monetize its botnet, offering a peek at the ways modern cybercriminals operate and the challenges these pose.
