The payload is the actual data. Referring back to the photo example, the thousands of packets that make up the image each have a payload, and the payload carries a little piece of the image. Where do packet headers come from? In practice, packets actually have more than one header, and...
they consist of a header, payload, and trailer and include a destination and source address, which respectively signify where they’re headed and where they originate. Although packets travel between networks, frames do so between computers — therefore, they’re at Layer 2 of theOpen Systems In...

a previously unknown vulnerability in iOS, this exploit, without any user input, triggered the execution of malicious code that connected to a C2 server and gradually loaded additional malicious payload. It first elevated privileges using additional exploits and then launched a full-blown APT platform...
Packet headers and trailers: All data that is sent over a network is broken down into smaller pieces called packets. Packets contain both a payload, or the actual data being sent, and headers, or information about that data so that computers receiving the packets know what to do with them....
Pass the hash is a type of cybersecurity attack in which an adversary steals a “hashed” user credential and uses it to create a new user session on the same network.
