Payload in computing (sometimes referred to as the actual or body data) is the cargo of a data transmission. It is the part of the transmitted data which is the fundamental purpose of the transmission, to the exclusion of information sent with it (such as headers ormetadata, sometimes referred to as overhead data) solely to facilitate delivery.[1][2]
In the analysis of malicious software such as worms, viruses and Trojans, it refers to the software's harmful results. Examples of payloads include data destruction, messages with insulting text or spurious e-mail messages sent to a large number of people.
In computer security, payload refers to the part of a computer virus which performs a malicious action.
Definition of: payload
(1) Refers to the "actual data" in a packet or file minus all headers attached for transport and minus all descriptive meta-data. In a network packet, headers are appended to the payload for transport and then discarded at their destination. In a key-length-value structure, the key and length are descriptive data about the value (the payload). See protocol stack.
(2) In the analysis of malicious software such as worms, viruses and Trojans, it refers to the software's harmful results. Examples of payloads include data destruction, messages with insulting text or spurious e-mail messages sent to a large number of people.
