AI-Enabled Cybersecurity (The Derby Mill Series ep 35)

What happens when AI cyberattacks outpace AI cyberdefence?

October 13, 2026

Earlier this month, JPMorgan CEO Jamie Dimon remarked, “I wrote about cyber this year. I said, and I meant it, it’s our biggest risk. And that was a couple weeks before Mythos. And now it is our biggest risk by far.”

Then last week, The Wall Street Journal ran the headline “AI Just Found a Bug That Puts up to 70% of the World’s Websites at Risk; Artificial-intelligence tools helped find one of the most severe online bugs ever. Cyber experts are racing to patch it before hackers use AI to exploit it.”

Cybersecurity researchers, the accompanying story noted, had issued an alert about two AI-uncovered vulnerabilities in PHP (PHP: Hypertext Preprocessor), a programming language that powers most of the web, including WordPress and Wikipedia.

The same day, The Information reported a totally separate cyber attack: “A hacking group called CyberCartel used a web of AI agents powered by models from companies including Anthropic, SpaceX and Chinese lab Moonshot AI to automate cyberattacks against more than 400 Latin American financial targets, according to an investigation by the cybersecurity startup Straiker.” Two days later, The Atlantic ran the headline “Welcome to the Valley of Pain: An explosion of AI-powered hacks will reshape life online.”

All this was forecast at Intrepid’s June annual general meeting in London. The Derby Mill team and Gianni Cuozzo, the CEO and founder of Rome-based Exein S.p.A., an Intrepid portfolio company that produces cybersecurity software for AI-enabled physical connected devices, anticipated the coming surge in cyber attacks.

Recent advances in AI lower two costs that increase the likelihood of cyber attacks: 1) they drastically lower the cost of finding vulnerabilities in code, 2) they severely lower the cost of exploiting those vulnerabilities. While advances in AI also lower the costs of cyberdefence, the impact is not symmetric. The reason AIs advantage attackers more than defenders is due to their unpredictable error profiles, which are less problematic for attackers.

Sendhil Mullainathan summarized, “Both the discovery and the exploit [of the coding flaws] are now about to get orders of magnitude much bigger. So if you think of a tail risk for the entire economy, this type of thing is sitting on that. You could imagine an attack on the New York Stock Exchange that caused chaos or rewrote trades even just for 5 minutes…. it’s arguably the biggest near-term threat that is not really described because you forget how much of the economic system, the medical system, everything relies on technology.”
