BotNet News

A botnet is a network of malware-infected computers and devices (zombie computers) that are remotely controlled by an attacker or cybercriminal, known as a “bot herder.” The hackers can use the botnet to perform various attacks on victim systems and other users. These include distributed denial-of-service (DDoS) attacks, phishing campaigns, spam delivery, cryptocurrency mining, and stealing credentials and other sensitive information. Cybercriminals can also rent or sell access to large botnets, making them a valuable tool for malicious purposes.

Typically, attackers build botnets using freely available malware. They can install the malware in a number of ways including through phishing emails, software vulnerability exploits, drive-by downloads, and brute-force attacks on weak passwords. Once the malware is on a system, it can spread itself to other devices by attempting to connect to remote servers through unsecured channels like IRC networks or web domains. Some botnets operate in a centralized client-server model while others are decentralized through a peer-to-peer (P2P) architecture. The P2P botnets are harder to take down than centralized ones and provide more resilience for the bot herder against takedown attempts.

Once a device is infected with botnet malware, the attacker can control it remotely via commands from the command and control (C&C) server. Depending on the C&C architecture, the attack may run in a centralized manner or through a decentralized model. For centralized models, disabling the botnet requires shutting down the command and control center. However, with the technology market becoming oversaturated with low-cost, low-security IoT devices, it’s become more difficult for hackers to find and disable these control centers.
