What is a botnet?

A botnet is accurately defined as a collection of infected computers that are controlled by hackers. The individuals who create these botnets typically utilize malware to infect devices, turning them into "bots" or "zombies." Once a computer becomes part of a botnet, the hacker can remotely command it to execute various malicious activities, such as sending spam emails, launching distributed denial-of-service (DDoS) attacks, or stealing sensitive data.

This definition reflects the nature of botnets as networks of compromised machines that can be orchestrated by a central controller, allowing them to perform automated tasks without the owner’s consent. Understanding botnets is crucial in the cybersecurity field because they represent a significant threat, showcasing the potential vulnerabilities in connected devices and the importance of security measures to protect against infection and exploitation.
