RAT
Remote access trojan
Do they work if the target pc is turned off?
Can you remove it from the target pc whenever you want?
Can you do it without getting their ip?
It won't work if the target PC doesn't have net on.
You can remove it when you want.
I'm not sure if it deletes the RAT on their computer.
And they have to open the RAT, you don't get the IP.
Works like a keylogger.
But you will need to port forward.
