The Internet needs an antibotty immune system, stat

Overview

It has been reported that security researchers were stunned this week by claims that Anthropic’s Mythos Preview can autonomously compose high‑impact exploits. Allegedly, Mythos produced a browser exploit that chains four separate vulnerabilities and used a JIT heap spray to escape both renderer and kernel sandboxes. The speed and ease of chaining — turning vulnerability discovery into an energy problem — is the moment that set off alarm bells: this isn’t just smarter tooling, it’s a qualitatively different class of risk.

Why it matters

Why the panic? Because millions of embedded devices — routers, medical gear, industrial controllers — are out in the wild running software that can’t be easily updated. The old nightmare papers like “How to 0wn the Internet in your spare time” showed how worms can spread in seconds; now imagine an AI that not only finds holes but links tiny, mundane bugs into full‑blown breakouts. The emotional core here is acute: the Internet’s long tail of unpatchable devices looks less like inertia and more like a tinderbox.

The proposed fix: antibotty inoculation

The blog author argues we need aggressive, local defenses — “antibotty networks” that use frontier AI to proactively inoculate vulnerable hosts by applying beneficial attacks faster than adversaries can weaponize flaws. Think of it as immune therapy for the network: deploy AI agents that find and neutralize exploit chains on nearby devices in seconds. This idea echoes past work — Microsoft’s Vigilante proposal from 2008 and other academic attempts to outpace worms — but supercharges them with modern models that can reason about binaries without source code.

What to watch next

Skeptics will point to the ethics, legality and stability problems of letting defensive agents exploit devices at scale; others worry that attackers will simply use the same AI to escalate. Formal verification and unikernels are floated as long‑term guards, but the claim is that specification will always lag creative attack chains. So the near term looks messy: expect heated debate, prototype projects like Project Glasswing to attract attention, and a rush of research into safe, auditable “immune” tooling. Can we build a vaccine without accidentally unleashing a new pathogen? That’s the trillion‑dollar question.
