This payload can be used to prank friends by sending emails at top speed from their thunderbird clients. This payload opens a shell (or powershell if running on windows), starts the Thunderbird application, and via the CTRL N sequence starts the email sending functionality that is not protected by any security system. After that it writes the recipient's email, the subject of the email and the body of the message and sends.
This payload is for the USB Rubber Ducky — a "flash drive" that types keystroke injection payloads into unsuspecting computers at incredible speeds. It's no wonder this little quacker has made appearances on Mr. Robot, FBI, Blacklist, National Geography and more!
