Explanation

A flood of inbound connections from multiple, geographically diverse sources is the hallmark of a Distributed Denial-of-Service (DDoS) attack, which is a subtype of denial-of-service (DoS). The goal is to overwhelm the target's resources-bandwidth, processing power, or connection tables-until legitimate users cannot be served. Worms self-propagate through networks. Phishing uses deceptive emails to steal credentials. Viruses attach to programs and spread via user action. None of these produce the pattern of high-volume inbound traffic from many global sources.
