Explanation

A DDoS (Distributed Denial of Service) attack uses multiple systems (often dozens, hundreds, or thousands of compromised machines) to flood a single target with traffic or requests, overwhelming it and preventing legitimate users from accessing it. The key distinguishing factors here are: (1) multiple attackers/workstations, and (2) the goal of denying service. A Trojan (B) is malware that disguises itself as legitimate software. Cross-site scripting (C) is a web vulnerability that injects malicious scripts into web pages. A man-in-the-middle attack (D) intercepts communications between two parties. A replay attack (E) involves capturing and retransmitting valid data to impersonate a user.
