Modbus Banner Grabbing



This module grabs the banner of any device running the Modbus protocol by sending a request with Modbus Function Code 43 (Read Device Identification). Modbus is a data communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs).

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/scada/modbus_banner_grabbing
msf auxiliary(modbus_banner_grabbing) > show actions
msf auxiliary(modbus_banner_grabbing) > set ACTION < action-name >
msf auxiliary(modbus_banner_grabbing) > show options
    ...show and set options...
msf auxiliary(modbus_banner_grabbing) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
