Hi!

So the problem is how it is executed, you have to implement a function to execute files in remote host without waiting for a result, as the current functions does. Take as an example the upload and download file, both of this functions are implemented in our code, so you’ll need to do something similar (not the same) to execute the keylogger. I have implemented it in my own backdoor, but you’ll learn a lot if you do it your self.

Try it out and let me know how it goes!
