AI Gives Attackers OT Expertise on Demand. Here's What the Technique Looks Like on a Real PLC. (Part 1)

Earlier this week I said AI was closing the knowledge gap for attackers faster than the industry was ready for. This is the technique, demonstrated.
TL;DR for OT leadership: Threat actors no longer need years of industrial experience to plan targeted attacks on your operational process. They need your configuration files (logic exports, address maps, HMI project files, manufacturer reference documents) and access to a production AI tool. With those, the AI tool supplies the process expertise the attacker does not have. It reads the logic, infers the physics, maps cross-system dependencies, and produces ranked attack paths with protocol-level instructions for executing them. The industrial-process knowledge gap that used to be a natural barrier against precision attacks has collapsed. For leadership, that changes three priorities. First, configuration files are process intelligence and must be protected like safety documentation. That means backup validation, integrity checks, and inventories of every copy wherever it lives, including copies held by vendors and contractors, and copies on the IT network. Second, remote access to engineering workstations deserves the same scrutiny you apply to your highest-value production systems, because that is where the intelligence lives. Third, the investment required for an adversary to weaponize this technique is trivial. A single analyst workday and a few dollars of API cost. Assume it is in use today, and fund your teams accordingly.
