Thought I would share a reverse shell tool that I use a lot. Its called Reverse Shell Generator!
I love the fact that its so simple to use and it displays the main programming languages. To start, all you have to type in is RSG <IP Address> <Listening Port>. RSG will then display a list of one liner reverse shells that you can use.
It saves me so much time!! I usually have my reverse shells stored in /var/www/html/ folder, then I would copy it over and paste it in etc. With this, just launch it and pick the one you want while having a netcat listner waiting for the connection.
I hope its as useful for you as it has been for me.
