A portable file refers to an executable file or file format exploit that you can save to an external storage device. You create portable files when you want to send a malicious file to a human target using a delivery method other than e-mail. Portable files are most commonly used in USB key drops, but you can also save them to CD-ROMs or any other storage device.
A portable file is a campaign component and is created as part of a campaign. The portable file component generates a downloadable file that contains an embedded payload. The delivered payload establishes the connection between the victim’s machine and the attacking machine.
