Explanation

A Denial of Service (DoS) attack is an attempt to make a system or network unavailable or unresponsive by overwhelming it with excessive traffic or requests. A flood of malformed packets is a type of DoS attack that exploits the vulnerability of some systems or protocols to process packets that do not conform to the expected format or structure. These packets can cause errors, crashes, or resource exhaustion on the target system or network, preventing legitimate users from accessing it.
