The Anatomy of a Modern DDoS Attack

Modern DDoS attacks have evolved far beyond simple flooding techniques. Today's attacks are sophisticated, multi-layered operations that can adapt in real-time to defensive measures. Understanding how these attacks work helps in developing effective prevention strategies.

The attack typically begins with the creation or rental of a botnet. Cybercriminals infect thousands of devices with malware, turning them into "zombies" that can be controlled remotely. These devices include everything from personal computers and smartphones to Internet of Things (IoT) devices like smart cameras and routers.

Once the botnet is assembled, the attacker identifies a target and begins the assault. The compromised devices simultaneously send requests to the target, creating a massive spike in traffic. This traffic might consist of seemingly legitimate requests, making it challenging to distinguish between real users and attacking bots.
