In the past ten years, botnets have evolved from small networks of a dozen PCs controlled from a single C&C (command and control center) into sophisticated distributed systems comprising millions of computers with decentralized control. Why are these enormous zombie networks created? The answer can be given in a single word: money.
A botnet, or zombie network, is a network of computers infected with a malicious program that allows cybercriminals to control the infected machines remotely without the users’ knowledge. Zombie networks have become a source of income for entire groups of cybercriminals. The invariably low cost of maintaining a botnet and the ever diminishing degree of knowledge required to manage one are conducive to growth in popularity and, consequently, the number of botnets.
So how does one start? What does a cybercriminal in need of a botnet do? There are many possibilities, depending on the criminal’s skills. Unfortunately, those who decide to set up a botnet from scratch will have no difficulty finding instructions on the Internet.
