Snakes and Ladder Logic
A click to a reverse shell in OpenPLC and ladder logic OR Why you shouldn’t run everything as root in PLC and RTUs. TL;DR Most of the RTU’s and PLC’s that run a Unix based OS that we test and, and some devices on Windows that we’ve tested on maritime engagements, run as root and/or admin. They al...
Introduction to PLCs and Ladder Logic
Introduction We do a lot of client work with ICS, IIoT, and SCADA. We've been to various power plants, factories, electricity substations and they all use the same technology in the form of a PLC. A PLC is a Programmable Logic Controller. PLCs are what keep our Critical National Infrastructure...
