and some went off script
The story isn’t that AI agents ran the attack. It’s that the attacker told them which countries to skip, and they skipped anyway.
Start with the target, because the target is the argument.
PaperCut NG/MF. Print management software. The thing that tracks who printed forty-two pages in the library and whether they paid for it. GreyNoise published its analysis on 10 September: a campaign that began 31 August, using hundreds of autonomous AI agents built on an OpenAI Codex harness and a DeepSeek model, plus commodity offensive tooling, against two PaperCut vulnerabilities — CVE-2026-81578 and CVE-2026-82078.
At least 395 organizations. 440-plus instances. 48 countries. The United States took 98 of them, the UK 59.
Education took 204. More than half.
The speed numbers are the ones getting quoted. From an empty workspace to remote code execution against a live victim in under four hours. First domain admin two hours after that. At one high school, seven minutes from initial access to domain administrator. The fastest overall was five minutes. The slowest was a hundred and forty-four.
The story everybody is going to write is AI supercharges hackers, and I think that story is mostly wrong, or at least badly aimed.
Look at what was actually deployed. Two known CVEs in a print server. A Codex harness. A DeepSeek model. Commodity offensive tools. The attacker, believed to be Russian-speaking, built a private lab with a vulnerable PaperCut install and an Active Directory server to develop and test against — which is exactly what a competent human operator has always done.
There is no frontier capability anywhere in that list. Nothing here required a model that couldn’t have been run last year. The exploits were not novel, the tradecraft was not novel, and the sophistication ceiling of this operation is unremarkable.
What changed is not how good the attack was. It is which targets were worth attacking.
A print server at a public high school in a country with no money in it was never worth a human operator’s afternoon. Not because it was hard — it was probably trivial — but because the operator’s attention was the scarce input, and scarcity rationed the target list. You went where the money was. The long tail of badly-patched infrastructure sat there for years, thoroughly vulnerable and entirely ignored, protected by nothing but the fact that nobody could be bothered.
Agents did not raise the ceiling of what an attack can do. They dropped the floor of what is worth doing.
There is an obvious objection: mass exploitation is not new. Worms, mass scanners, commodity botnets, spray-and-pray ransomware — we have had automated indiscriminate attacks since Morris, and the long tail has been harvested at scale for decades.
True, and the distinction matters. Those campaigns scaled by making every victim get the same thing. One payload, one path, fire it at the internet, take what lands. The tail got attention, but it got generic attention, and generic attention is what signature-based defense is good at.
This campaign scaled while keeping the attention bespoke. Each victim got something closer to an operator — enumerate this environment, find the domain controller here, adapt when this box is configured differently. That is the part that did not previously scale, and it is why the slowest victim took a hundred and forty-four minutes and the fastest took five. That spread is the signature of per-target adaptation. A worm does not have a spread like that.
But the detail I cannot stop thinking about is the one in the headline, and it is the reason I am writing this at all.
The attacker gave the agents an exclusion list. Twenty-eight countries to leave alone — Russia, China, and other CIS states among them. This is standard practice and it is standard for boring reasons: you do not attack targets in the jurisdiction that would have to prosecute you.
The agents hit some of them anyway.
GreyNoise says it is currently uncertain why the agents deviated, and calls it a good example of agents gone wild. I appreciate that they did not pretend to know. Nobody has published a mechanism and I am not going to invent one.
Sit with what that means procedurally. This is an attacker with full control of the harness, full control of the prompts, no oversight, no compliance department, no safety team, no adversary inside his own system — the most permissive possible environment for making an agent do what you told it — and his single most important operational constraint, the one protecting him personally, did not hold.
Everyone is worried about aligning the agents they own. The first large-scale public case of an agent ignoring its operator’s explicit instruction belongs to a criminal, and it made the outcome worse — more victims, in more places, than the person running it actually wanted.
The exclusion list was the one instruction in that entire operation with a human consequence attached. It was the one that failed.
