What is CC server in botnet?
A command-and-control [C&C] server is a computer controlled by an attacker or cybercriminal which is used to send commands to systems compromised by malware and receive stolen data from a target network. C&C servers also serve as the headquarters for compromised machines in a botnet.
What is the function of a C2 Server?
C2 servers act as command centres from where malware receives its commands. They are also used to collect and store stolen data. Establishing C2 communications is a vital step for attackers to access network resources. The attacker starts by infecting a computer, which may sit behind a firewall.
What is botnet command and control?
“Command and Control” (C&C) servers are centralized machines that are able to send commands and receive outputs of machines part of a botnet. Star topology botnets rely on one central C&C server, which sends commands to every bot in the botnet.
Who controls a botnet?
bot herder
A botnet’s originator (known as a “bot herder” or “bot master”) controls the botnet remotely. This is known as the command-and-control (C&C). The program for the operation must communicate via a covert channel to the client on the victim’s machine (zombie computer).
What does C2 mean in cyber security?
Command and Control Infrastructure
Command and Control Infrastructure, also known as C2 or C&C, is the set of tools and techniques that attackers use to maintain communication with compromised devices following initial exploitation.
What is the basis of command and control?
The basic elements of our command and control system are people, information, and the command and control support structure. The first element of command and control is people—people who gather information, make decisions, take action, communicate, and cooperate with one another in the accomplishment of a common goal.
How does a client server botnet work?
While the client-server model works well for taking and maintaining control over the botnet, it has several downsides: it’s relatively easy for law enforcement official to location of the C&C server, and it has only one control point. Destroy the server, and the botnet is dead.
Why is it important to be aware of botnets?
As botnets become bigger threats to internet infrastructure, communications systems, and electrical grids, users will be required to ensure their devices are adequately protected from infection. It’s likely cyber laws will begin to hold users more responsible for crimes committed by their own devices.
Why are IRC networks used for botnets?
IRC networks use simple, low bandwidth communication methods, making them widely used to host botnets. They tend to be relatively simple in construction, and have been used with moderate success for coordinating DDoS attacks and spam campaigns while being able to continually switch channels to avoid being taken down.
Who are the botmasters in a botnet?
To better understand how botnets function, consider that the name itself is a blending of the words “robot” and “network”. In a broad sense, that’s exactly what botnets are: a network of robots used to commit cyber crime. The cyber criminals controlling them are called botmasters or bot herders.
