In computing and cybersecurity, a "payload" refers to the part of a data transmission that contains the actual intended message or information. This can include files, commands, or any data that is sent over a network. The payload is distinct from the headers or metadata that help route the data but do not contain the core content. In the context of malware, a payload is the component that executes harmful actions on a target system. For example, a virus may deliver a payload that corrupts files or steals sensitive information. Understanding payloads is crucial for cybersecurity professionals to protect systems from potential threats.
