What is the purpose of a botnet in malware?

### REPLY:
The purpose of a botnet in malware is to create a large network of infected computers that can be remotely controlled by the attacker. These compromised machines can be used to carry out various illegal activities, such as launching coordinated attacks on websites or servers, sending out massive amounts of spam emails, distributing malware to other systems, or even mining cryptocurrencies using the combined computational power of the botnet.
