Simple list This is the simplest payload type, and lets you configure a simple list of strings that are used as payloads. You can manually add items to the list using the text box and the “Add” button, or you can paste a list from the clipboard, or load from file. The “Deduplicate” option will remove duplicate entries from your list. This increases the efficiency of your attacks by reducing the number of requests that will be sent.
Runtime file This payload type lets you configure a file from which to read payload strings at runtime. This is useful when a very large list of payloads is needed, to avoid holding the entire list in memory. One payload is read from each line of the file, hence payloads may not contain newline characters.
