A Distributed Denial-of-Service (DDoS) attack is designed to saturate the target with excessive traffic, making it difficult or impossible for legitimate users to access services. This attack uses multiple compromised systems as sources of attack traffic. A virus, by contrast, is a program that can copy itself and typically has a detrimental effect, such as corrupting the system or destroying data. Phishing involves attempting to acquire sensitive information by masquerading as a trustworthy entity in an electronic communication. A worm is similar to a virus but is a standalone malware that replicates itself in order to spread to other computers.
