Usage Tips

List Payloads and Payload options

msfvenom --list payloads
msfvenom -p [payload] --payload-options
msfvenom -p windows/meterpreter/reverse_tcp --payload-options

List Encoders

msfvenom --list encoders

Encoding your payload in x86/shikata_ga_nai is great, but sometimes your shell code has bad chars and shikata_gi_nai may throw an error on generation. Using this command you should be able to find an encoder that will fit your parameters.

Formats

You can generate the shell output in two different formats: Executable or Transform. It will depend on the scenario as to which one you’ll choose.

Executable - It’s own executable shell with an extension .elf .exe .py .php etc. Eg: You have an unstable non-interactive low priv shell and you want to get something more stable and efficient on a vulnerable windows machine. You’d generate the payload as an .exe, create a listener, upload and execute.

Transform - Raw shellcode that can be pasted into an existing exploit. The transform format will depend on what that exploit is written in. Eg: You need to create shell code to paste into your code execution exploit that’s ultimately ran by a vulnerable public facing web app in javascript. To format your shellcode, you may want to use: –format js_le (JavaScript_LittleEndian)
