BOTNET spreading detection and prevention via website

Abstract

In this article the botnets are described which are considered to be among the biggest threats to computer network. Botnet is a network of compromised computers on which remote controlled programs (bots) are installed. The main purpose of botnets is to use hijacked computers for various fraudulent online activities. The botnet evolution from centralized towards Peer-to-Peer control mechanism is discussed and possible causes of such approach are described. Botnet propagation methods and development tendencies, including propagation through compromised public websites, when botnet creators have opportunity to passively attack website visitors` computers for further botnet expansion by inserting malicious code in compromised websites, are analyzed. Several botnet detection and propagation via websites prevention methods are proposed as a part of botnet spread prevention model.
