secondly how to deliver them (mechanism tools techniques everything :-D)
Remote Administration Tool a.k.a RAT are found all over the internet , but as they are illegal so you can not find them on very straight forward website. Due to the fact that they are not that easy to find , cracked versions of the same programs (Darkcomet , NJRat etc) are available but DO NOT INSTALL such nulled / cracked versions as with every program they are backdoored and might compromise your own system. Tutorial to install a RAT and how to setup a RAT will be explained here.
As I said internet is full with everything but we need to search a bit before we could get going .Please note that we do not promote anything illegal , but just answering your question of HOW to get a RAT?
there are many sites which offer such services where RAT Developers sell their code.Two of the most famous such sites are
I will write a detailed tutorial , and I will call our trojan Universal RAT for this guide.
Port forwarding might differ in your router a bit but you can find all the detail of forwarding from Port Forward as it is a great website and covers everything in detail , but the question is which port to forward ? Please note that you can not forward common ports already used by other services like Port 80 ,443,21 etc. You can forward a port range from 1337-1339 . I have always used 1337 ;)
Once you have your port forwarded open "Socket" or "listening port" in Universal RAT and set the port you forwarded above ...
thats about all with the basics of port forwarding but do keep in mind two important things, if you have a RAT which is detected by AV it is no good so you will need to make it FUD (Fully Undetectable) and that is achieved by using various Crypters which make your Trojan FUD. you can get those in the sites I mentioned above, you can also make your RAT FUD/ UD by Hexing but I think that won't be your cup of tea.
Have Fun and remember its illegal to break into other people system without their consent.
I almost forgot to explain this
Many Routers are enabled with UNPN function if you use some Torrent Client like uTorrent it means , UnPN is active.
Open Universal RAT and go to "Socket" , " Incoming / Listening Port" and set any Port number, let say 1337. Keep your RAT open and open up uTorrent and click on Option > Preferences and type port 1337 in Listening Port
After Clicking OK you have done Port forwarding using UNPN.
