Understanding Botnets: How Cybercriminals Use Networks of Infected Devices to Carry Out Attacks

Types of Botnets

There are several types of botnets that are commonly used by cybercriminals to carry out malicious activities. These include:

1. Command and Control (C&C) Botnets

These are the most common type of botnets and are controlled by a central server. The server sends commands to the infected devices, which then carry out the specified actions. C&C botnets are often used for DDoS attacks, spamming, and stealing sensitive information.

2. Peer-to-Peer (P2P) Botnets

These botnets are decentralized and do not rely on a central server. Instead, they use a network of infected devices to communicate with each other and carry out commands. P2P botnets are often used for spamming and phishing attacks.

3. Proxy Botnets

Proxy botnets are used to hide the real location of the attacker. The infected devices act as a proxy server, allowing the attacker to carry out their activities without being traced.

4. Spam Botnets

As the name suggests, these botnets are used for sending spam emails. The infected devices are used to send large volumes of spam emails, often promoting illegal or fraudulent activities.

5. Banking Trojans

These botnets are designed to steal sensitive financial information, such as credit card numbers and bank account details. They often use keyloggers or fake login pages to capture the victim's information.

6. Mobile Botnets

These botnets target mobile devices, such as smartphones and tablets. They are often used to send spam messages or steal personal information stored on the device.
