These bots produce a huge amount of malicious bot traffic specifically targeting paid ads to engage in ad fraud. Responsible for fraudulently clicking paid ads, this non-human traffic costs advertisers billions every year and is often disguised as legitimate traffic. Without good bot detection software, this bot activity can cost advertisers a large proportion of their ad budget.

Bots which are used for overloading mail servers or carrying out large-scale data theft.
Why do cybercriminals use bots?
Hackers may use botnets to send phishing or other scams to trick consumers into giving away their money. They may also collect information from the bot-infected machines and use it to steal identities and incur loans or purchase charges in the user’s name.
2. To attack legitimate web services
Criminals may use botnets to create DoS and DDoS attacks that flood a legitimate service or network with a crushing volume of traffic. The volume may severely slow down the company’s service or network’s ability to respond, or it may entirely overwhelm the company’s service or network and shut them down.
3. To extort money from victims
Revenue from DoS attacks comes through extortion (i.e., pay or have your site taken down) or through payments by groups interested in inflicting damage to a company or network. These groups include "hacktivists" — hackers with political agendas as well as foreign military and intelligence organizations.
Cybercriminals may also lease their botnets to other criminals who want to send spam, scams, phishing, steal identities, and attack legitimate websites and networks.
