A type of attack that seeks to disrupt legitimate use of a system by overwhelming it is called a Denial of Service (DoS) attack. These attacks flood the target with excessive traffic, making it difficult or impossible for legitimate users to access the services. They can be executed using various methods, including botnets, to amplify the impact on the target's resources. The primary goal is to interrupt the normal operations of the targeted system by exhausting its network bandwidth, CPU, or memory.
