Often, the botnet can grow itself, for example by using infected devices to send out spam emails, which can infect more machines.īotnet owners use them for large-scale malicious activity, commonly Distributed Denial of Service (DDoS) attacks. Many threat actors are actively engaged in building massive botnets, with the biggest ones spanning millions of computers. Any device that becomes infected starts communicating with a Command and Control (C&C) center and can perform automated activities under the attacker’s central control. There are many types of malware that infect end-user devices, with the objective of enlisting them into a botnet. Other bots are malicious-for example, bots used to automatically scan websites for software vulnerabilities and execute simple attack patterns. Some bots are legitimate-for example, Googlebot is an application used by Google to crawl the Internet and index it for search.
