Writing Shellcode to a File

Peleus

This really is a trivial code snippet, but as with most scripts it comes in handy because it simplifies even a basic task further. Save this to a simple filename like ‘hex2file’ and place it in your /usr/bin directory. Whenever you need to write out hex characters directly to a file use the following syntax.

hex2file 4142434445 > hexfile.bin

hex2file 4142434445 > hexfile.bin

Creating Metasploit Payloads

Peleus

Often one of the most useful (and to the beginner underrated) abilities of Metasploit is the msfpayload module. Multiple payloads can be created with this module and it helps something that can give you a shell in almost any situation. For each of these payloads you can go into msfconsole and select exploit/multi/handler. Run ‘set payload’ for the relevant payload used and configure all necessary options (LHOST, LPORT, etc). Execute and wait for the payload to be run. For the examples below it’s pretty self explanatory but LHOST should be filled in with your IP address (LAN IP if attacking within the network, WAN IP if attacking across the internet), and LPORT should be the port you wish to be connected back on.
