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 Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/scada/koyo_login
msf auxiliary(koyo_login) > show options
    ... show and set options ...
msf auxiliary(koyo_login) > set RHOSTS ip-range
msf auxiliary(koyo_login) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(koyo_login) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(koyo_login) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(koyo_login) > set RHOSTS file:/tmp/ip_list.txt

Required Options

  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
