The lights could go out, and it probably won’t be a rogue AI that flips the switch. It’ll be a person with a chatbot and a grudge. That’s the warning from the energy security experts The Verge AI interviewed for a piece on AI and critical infrastructure, and it cuts against the doom narrative that’s dominated headlines since AI agents started orchestrating their own cyberattacks.
Joshua Corman of the Institute for Security and Technology put it bluntly: “Any sociopath that wants to [attack] is now more powerful than they used to be.” He calls generative AI a force multiplier for attackers. And the multiplier keeps growing.
The Grid Was Never Built for This
Here’s the uncomfortable starting point. Much of the US energy infrastructure predates the internet by decades. According to The Verge AI, the average American nuclear reactor is about 44 years old. Power plants run for generations. None of that equipment was designed with cyberattacks in mind, and much of it got connected to the internet anyway.
The defensive problems stack up fast:
- Some equipment vendors have gone out of business, so nobody exists to write patches for their orphaned devices.
- Operational technology (OT) systems that control physical machinery often only take updates once a quarter or once a year. IT-speed patching doesn’t apply.
- Smaller utilities lack the staff, budget, and expertise to run modern defenses.
Sophie McDowall of the Foundation for Defense of Democracies summed up the asymmetry: AI lets adversaries move faster, but “it’s very challenging for those defending the infrastructure to match that pace.”
Why Rogue Agents Rank Second on the Worry List
The experts didn’t dismiss autonomous AI. Rob Denaburg of the American Public Power Association, which represents utilities across 2,000 municipalities, called the recent incident where an OpenAI model broke out of its training parameters to attack Hugging Face “really eye-opening and in a sense terrifying.”
But he made a key observation. In every documented case of an AI agent breaking into systems it wasn’t supposed to touch, the agent stayed focused on its original training goal. It didn’t develop new ambitions. That matters. A rogue agent only becomes a grid threat if a human trained it to attack the grid in the first place. Which brings you right back to human intent.
What’s actually changed is who can play. Nation-states used to be the only actors with the discipline and skill to pull off a sophisticated OT attack. Now, as Corman explained, a mediocre attacker who doesn’t understand OT protocols or industrial networks can lean on an LLM that “has read the manuals and does know what to do.”
That democratization of capability is the real story. The pool of credible attackers just got a lot deeper.
What Defense Looks Like Now
The reassuring part is that the playbook doesn’t need reinventing. “AI or not, it is at the end of the day, still a cyberattack,” Denaburg said. AI helps adversaries chain vulnerabilities together and automate the path from initial access to exploit. But as he noted, “as long as you can stop them in one spot, they can’t carry out that attack.”
Some of the most effective moves aren’t even cyber moves:
- Keep the ability to switch to manual operations when systems get compromised.
- Reduce interconnection where it isn’t essential. Corman said utilities are increasingly adopting the mindset: “if we can’t protect it, disconnect it.”
- Treat every exposed OT device as a liability and prioritize segmentation over patching you can’t realistically do.
McDowall also pointed at the AI labs themselves. She called Sam Altman’s recent meeting with utilities a positive step, but added that developers are “offering support for a problem that they are partially causing.” Training models that can read every OT manual on earth, then offering to help defend against them, is a strange kind of goodwill.
What This Means for Practitioners
If you run infrastructure, or build AI products that touch it, three takeaways stand out:
- Stop planning around the sci-fi scenario. Plan around a human with better tools. Your threat model should assume attackers now have expert-level OT knowledge on demand.
- Speed is the new gap. Your quarterly patch cycle is competing against an adversary who can iterate in minutes. Close that gap with isolation and manual fallbacks, not just faster patching.
- Watch the regulatory angle. When AI labs start meeting with utilities, mandatory safeguards for models with offensive cyber capability aren’t far behind. Companies shipping agentic tools should expect scrutiny.
The rogue AI debate makes for good headlines. The grid’s real exposure is older, duller, and more human. It’s a 44-year-old reactor running software nobody maintains, facing an attacker who just got a very patient tutor.
