Which type of attack utilizes multiple computers to overwhelm a single system?

A Distributed Denial of Service (DDoS) attack involves multiple compromised computer systems that work together to flood a single target with traffic, ultimately overwhelming that system and rendering it unable to function properly. This is achieved by utilizing the combined bandwidth and resources of the many devices involved in the attack, which can include personal computers, servers, or IoT devices that have been infected with malware and turned into "bots."

The primary goal of a DDoS attack is to disrupt the services of the targeted system, making it unavailable to its intended users. By using numerous devices, the attack minimizes the chances of defending against it because the sheer volume of requests can easily surpass any defenses the target may have in place, such as firewalls or traffic filters.

Other types of attacks mentioned do not utilize multiple computers in this way. Phishing attacks typically involve deceptive emails or messages to trick individuals into divulging personal information, while man-in-the-middle attacks focus on intercepting communications between two parties but do not incorporate multiple systems overwhelming a single target. SQL injection attacks exploit vulnerabilities in web applications to execute malicious SQL code, targeting databases rather than overwhelming a system with traffic. Thus, the DDoS attack stands out for its unique nature of utilizing many compromised
