Understanding Botnets and Their Operations

Summary

An overview of what botnets are, how they are formed, and how they function under the control of a botmaster.

A botnet consists of a network of compromised devices, such as computers, smartphones, and IoT gadgets, which are managed by a third party called a botmaster using command and control software.

Botnets are created by infecting vulnerable systems via phishing or social engineering, establishing a connection through standard protocols like HTTP or IRC, allowing the botmaster to remotely command the bots to execute malicious tasks.

Original text

A botnet is a network of compromised computers, also known as zombies or bots, that are controlled by a third party, often referred to as a botmaster. These compromised devices can include computers, smartphones, or Internet of Things devices whose security has been breached. The botmaster uses command and control software to direct the activities of these compromised devices.
Botnets start with the botmaster identifying vulnerable systems and using social engineering techniques like phishing to install a small executable file on the target system. Once installed, the bot communicates with the botmaster through a command and control channel, often using existing protocols like IRC or HTTP to avoid detection. The botmaster can then issue commands to the bots, which can perform various malicious activities.
