Financial botnets, like the ZeuS botnet, have been responsible for attacks involving millions of dollars stolen directly from multiple enterprises over very short periods of time. Financial breachвЂ“ includes botnets specifically designed for the direct theft of funds from enterprises and credit card information.DDoS attacks target organizations for personal or political motives or to extort payment in exchange for ceasing the attack. DDoS attacksвЂ“ leverages the massive scale of the botnet to overload a target network or server with requests, rendering it inaccessible to its intended users.They are also used to spread bots to recruit more computers to the botnet.

The Cutwail botnet for example, can send up to 74 billion messages per day. They are primarily used for sending out spam messages, often including malware, in towering numbers from each bot.

Email spamвЂ“ though email is seen today as an older vector for attack, spam botnets are some of the largest in size.

As a result, bot-herders are often able to rent access to segments of their botnet on the black market for significant financial gain. Since botnets remain under control of a remote attacker, infected machines can receive updates and change their behavior on the fly. The scale of a botnet (many comprised of millions of bots) enable the attacker to perform large-scale actions that were previously impossible with malware. From one central point, the attacking party can command every computer on its botnet to simultaneously carry out a coordinated criminal action. A botnetВ (short for вЂњrobot networkвЂќ) is a network of computers infected by malwareВ that are under the control of a single attacking party, known as the вЂњbot-herder.вЂќ Each individual machine under the control of the bot-herder is known as a bot.
