Schneider Modicon Remote START/STOP Command

The Schneider Modicon with Unity series of PLCs use Modbus function code 90 (0x5a) to perform administrative commands without authentication. This module allows a remote user to change the state of the PLC between STOP and RUN, allowing an attacker to end process control by the PLC. This module is based on the original 'modiconstop.rb' Basecamp module from DigitalBond.
