Koyo DirectLogic PLC Password Brute Force Utility



This module attempts to authenticate to a locked Koyo DirectLogic PLC. The PLC uses a restrictive passcode, which can be A0000000 through A9999999. The "A" prefix can also be changed by the administrator to any other character, which can be set through the PREFIX option of this module. This module is based on the original 'koyobrute.rb' Basecamp module from DigitalBond.

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/koyo_login
msf auxiliary(koyo_login) > show actions
msf auxiliary(koyo_login) > set ACTION < action-name >
msf auxiliary(koyo_login) > show options
    ...show and set options...
msf auxiliary(koyo_login) > 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.
