Payloads
A malicious payload is the executable code within malware that performs harmful actions. These payloads are typically delivered through phishing emails, malicious links, infected file attachments, and exploit kits.
There are two main types of payloads. The first, non-staged, is when all of the code is sent at the same time, they are larger in size, and won’t always work. The second, staged, is when the payload is sent in multiple phases, each phase needs to get the code for the next one, thus, this type can be less stable.
