D
distributed denial-of-service attack(DDOS attack)
A malicious activity in which cyberattackers use multiple computers (sometimes thousands) to engage in a synchronized attack on a targeted system. Attackers often launch DDOS attacks from botnets, a collection of malware-infected devices that act in response to commands from a botnet command and control. Like a denial-of-service attack, the attackers overwhelm the targeted system with spurious requests, making the system difficult or impossible for its intended users to reach.
