BotNet News

A botnet is a network of computers and IoT devices that have been infected with malware and are under the control of a criminal. Threat actors use these networks to perform a range of attacks including DDoS, data theft, and cryptojacking. They can be deployed to attack businesses for financial gain, or they can be used as cyber weapons in cyber warfare scenarios, posing serious national security risks.

To create a botnet, criminals infect devices with malware that is typically spread through phishing campaigns, software vulnerabilities, or firmware exploits on routers and IoT gadgets. Once these devices are infected, they become part of a botnet and can be remotely controlled by a criminal known as a “botmaster” without the device owner’s knowledge or consent.

The bots in a botnet communicate with a command and control server (C&C) to receive instructions. A C&C server acts as the central hub for a botnet, enabling the botmaster to control thousands or millions of devices at once.

Originally, botnets were created to make time-consuming tasks easier for criminals such as proctoring chatrooms and ejecting people who violate room policies. Today, adversaries use bots to do everything from harvesting passwords and other sensitive information to stealing money via phishing campaigns and DDoS attacks.

Modern botnets can be either centralized or peer-to-peer (P2P). The centralized client-server model was the first established, and it uses a single server to operate the botnet. The drawback of this model is that if the command and control server is discovered and dismantled, the entire botnet becomes useless. P2P botnets use advanced evasion techniques such as fast-flux DNS and domain-generation algorithms to mask their identity, making them hard to detect and shut down.
