What is a c2 server?

A C2 (command and control) server is a type of server that is used by hackers and other cyber criminals to manage and control a network of compromised computers or "botnet." The C2 server acts as a central command center for the botnet and can issue commands to all of the infected computers, such as instructing them to start a DDoS attack or to send spam emails.

Generally, C2 servers are hidden and hard to detect. They often use techniques like domain generation algorithms (DGAs) to constantly change their internet domain names, which makes it difficult for security analysts to track and shut them down.

C2 servers can be located anywhere in the world and are typically run by criminal organizations or state-sponsored hacking groups. They can be used for a variety of malicious activities, including data theft, espionage, and ransomware attacks.
