What is a Botnet?
Botnets are an increasingly prevalent type of malware. They are used by malicious actors to conduct DDoS attacks, steal data, and send spam. There are two main types: peer-to-peer (P2P) botnets and client-to-server (C2S) botnets. The difference is in how they communicate with each other.
P2P botnets use a peer-to-peer network to distribute the latest malware. These botnets are generally more resilient than C2S ones.
However, it is important to note that a P2P botnet isn’t always easy to disrupt. This is particularly true in countries where law enforcement is weak.
To create a botnet, an individual or group of individuals first needs to gain access to the device connected to the Internet. Once the device is compromised, it can be slowed down and manipulated.
In most cases, the botmaster can rent out a segment of the botnet for a fee. Alternatively, the botmaster can sell online credentials for a profit.
Infected devices may also be used for secret tasks. The remote attacker can alter a device’s behavior or even modify its files. Getting back control of a computer could involve reformatting the device or flashing its firmware.
Most botnets are controlled by several bot-masters. These individuals can use proxies and shells to hide their identities.
The primary objective of a botnet is to infect as many connected devices as possible. They can also automate repetitive tasks or send spam.
While most botnets use a client-server model, some employ a more sophisticated command and control (C&C) protocol. This allows the bot-master to speed up operations.
