Hi,
I created a payload .exe file that shutdown scammer's computer in loop.
Basically the file once executed it copy itself on Startup and shutdown the computer.
Next time when the scammer turn the computer on the file shutdown the machine automatically.
I added CityBank logo as icon.
TEST THE FILE ONLY INTO YOUR VIRTUAL MACHINE
You can download the file from here: shorturl.at/wAJKS
Have fun!
