Botnet A: Botnet A is an established botnet that has already compromised a large number of devices worldwide. It is under the control of a cybercriminal group and used for various malicious activities, such as launching DDoS attacks or distributing malware.

Botnet B: Botnet B is a relatively smaller botnet that is operated by a different cybercriminal group. They have identified Botnet A as a lucrative target for their own purposes.

Reconnaissance: The operators of Botnet B conduct thorough reconnaissance to gather information about Botnet A's infrastructure, including its command and control (C&C) servers, communication protocols, and potential vulnerabilities.

Exploitation: After identifying potential vulnerabilities in Botnet A's C&C servers, the operators of Botnet B develop or obtain exploit tools to take advantage of these weaknesses. They might discover a known vulnerability in the C&C software or server configuration that allows unauthorized access.

Gaining Control: With the exploit tools in hand, the operators of Botnet B launch targeted attacks against Botnet A's C&C servers. They successfully exploit the vulnerabilities, gaining unauthorized access and taking over the command and control mechanisms.

Herding/Farming: Now in control of Botnet A, the operators of Botnet B redirect its compromised devices to their own infrastructure. They reconfigure the compromised devices to communicate with Botnet B's C&C servers instead. The devices that were originally part of Botnet A are now effectively part of Botnet B.

Utilizing the Hijacked Botnet: The operators of Botnet B can now utilize the compromised devices from Botnet A for their own malicious activities. They can deploy various attacks, such as launching DDoS attacks against targeted websites or networks, distributing malware or spam, or even selling access to the compromised devices to other cybercriminals.
