Background for this topic.
A botnet is a network of compromised internet-connected devices controlled remotely by an attacker through malware. These devices, known as bots, receive commands from centralized or decentralized command-and-control (C2) servers to perform coordinated actions such as launching Distributed Denial of Service (DDoS) attacks, sending spam, or distributing additional malware. Botnets vary in size and complexity, often leveraging vulnerabilities in devices or weak authentication to propagate.
In information security, botnets pose significant risks including large-scale service disruptions from DDoS attacks and the unauthorized use of infected devices for malicious activities. Detecting botnet activity involves monitoring network traffic for unusual patterns and identifying communication with known C2 infrastructure. Effective defense includes timely patching of vulnerable systems, blocking C2 domains or IPs based on threat intelligence, and isolating infected hosts to prevent further spread or damage. Coordinated efforts to disrupt botnet infrastructure can reduce their operational impact.
