What is a botnet?

A botnet, also known as a robot network, is a type of malware that infects networks of computers and places them under the control of a single attacker known as a “botherder.” A bot is a self-contained machine that is managed by bot herders. The attacker serves as a command centre for the bots, allowing them to carry out simultaneous and coordinated illegal operations.

Because a bot herder may handle millions of bots at once, the botnet is a large-scale attack. The attacker may send updates to all botnets, causing them to modify their behaviour in real-time.
