What are botnets and how do infected devices combine into distributed networks?

A botnet is a network of infected computers and other digital devices that attackers manage remotely and centrally without the knowledge of their owners. Each infected device in such a structure is called a bot or zombie computer. The creation of botnets begins with the mass infection of user machines using trojans, worms, or exploits.

After successful deployment, the malware establishes a secure connection with the attackers' Command and Control (C&C) server or organizes a decentralized peer-to-peer network where each bot can receive and transmit commands. Botnets are used to organize large-scale DDoS attacks, mass spam distribution, cryptocurrency mining, and the collection of confidential information.

To protect your device from being included in a botnet, it is recommended to perform the following actions:

Monitoring the state of your home and work network allows you to detect abnormal traffic in a timely manner. Preventing unauthorized access to devices reduces the overall efficiency of cybercriminals and protects user privacy.
