Now that you have everything set up you are ready to put the ducky into a victims computer anywhere in the world. The only thing that can stop this is if the victims network fro some reason blocks inc or outgoing. In that case just change the port number. Ive tested this on a few Windows 7 systems and it went undetected on all of them.
Each one had anti virus such as Mcafee and Norton. Firewalls on as well. You may have noticed I have some long delays. I have long delays because I tested on fast and SLOW computers which required the longer delays to work.
You may also notice the "start" before the actual nc reverse shell command. Doing this enables us to exit out of the command prompt leaving less traces of the backdoor. So the only way the victim will see the backdoor is if they check things like task manager. Let me know what you think guys.
I know this one may be annoying because of the FTP server aspect of it. But if you end up trying it I assure you, you won't be disappointed.

Thanks, Tom. RE: Netcat reverse shell and ftp. Hello, The answer is that it can be done in many ways and everything depends on the attackers imagination.
