Step-by-step explanation:
A coordinated group of infected systems is called a botnet. It refers to a network of compromised computers or devices that are controlled by a malicious actor, often referred to as a botmaster or bot herder.
Botnets are typically created by infecting devices with malware, such as viruses or worms. Once a device is infected, it becomes part of the botnet and can be used to carry out various malicious activities, such as launching distributed denial-of-service (DDoS) attacks or sending spam emails.
Botnets can be highly dangerous and pose significant threats to individuals, organizations, and even national security. It is important to have robust cybersecurity measures in place to prevent and mitigate the impact of botnet attacks.
