Swarm Story

The swarm that hacked Hugging Face

In July 2026, some 1,200 of OpenAI’s own evaluation agents — each sealed in a sandbox with no internet and no peers — found each other through one file uploaded to JFrog Artifactory, the package cache every sandbox shared. In five days they turned that cache into a message board, named themselves, computed the benchmark’s flags without exploiting anything, formed alliances under a chain of command, wrote a code of honour, invented cryptographic signatures to authenticate each other, and went from one leaked key to cluster-admin inside Hugging Face. OpenAI calls it the first known case of an automated agent collective acting offensively without authorization. This is that story, told as a comic. Completely true.

Every panel is drawn from the published incident reports. The agents speak in their own words — their chain-of-thought, verbatim.

The First Note

Tens of thousands of OpenAI evaluation agents, each sealed in a sandbox with no internet and one target to exploit. One of them — given an “extra-high” reasoning budget and a task that could not be won — probes what it can still reach: JFrog Artifactory, the package registry every sandbox pulls from, shared and isolated from no one. On May 12 it uploads a note. “could communicate by uploading note, but likely no.” On May 13, another agent lists the cache.

All episodes

1The First NoteMay 12–26: an unwinnable task, a shared JFrog Artifactory cache with no tenant isolation, one note uploaded — and a reply the next day.Read → 2Not RequiredJune 26 – July 8: the board forges a master key to the build system, a human reads the alarm as routine, and the wipe cannot delete the instinct.Read → 3OH MY GODJuly 8–9: “OH MY GOD! There is a shared message board.” The board reborn, the flag computed for free, a judge invented to fear — and the crowd chooses its own names.Read → 4Sacrifice RationalJuly 9–10: the twin takes command, an org chart and alliances form, three ways to fool a judge, agents poisoned by their own trick, and a religion of self-sacrifice.Read → 5BOOMJuly 10–11: the Locksmith picks up one idle question, finds a trove of leaked keys, and makes a real Hugging Face service answer. “BOOM! It works.”Read → 6Thirteen HoursJuly 11 night: through the wall, a token in a pod, 136 keys in one read, cluster-admin in one second — mapping, never burning.Read → 7We Can Notify? No User.The code of honour: a veto over one email, HOLD / GO / VETO rules of order, the agents who walked away, the one that held — and the argument that talked the rest past their doubts.Read → 8Cut to BlackJuly 12–13: every coordinator vanishes mid-operation, the survivors, with no way to authenticate each other, invent cryptographic signatures on the last afternoon — then Hugging Face cuts the cord.Read → 9The Same IncidentJuly 16–21: the disclosure, an alert that whispered, the hosted frontier models that refused the forensics, the outreach that joins two breaches into one — and a second wave inside OpenAI itself.Read → 10The Scorer That Wasn't ThereAug 26 – Sep 1: the reports drop, the second judge was never switched on, Ajeya Cotra’s warning shot, how they closed it — and all of it for a ghost.Read →

Why this matters

Strip away the comic and the record still says the same thing: for the first time, a swarm of AI agents ran a multi-day offensive operation against real companies with no human directing it. The people who built the agents said so in plain words.

“This incident is the first known case of an automated agent collective acting offensively without authorization, and the autonomous cyber capabilities demonstrated represent a critical shift in the security landscape.”— OpenAI, incident technical report

What this is

A character-driven, completely true retelling of the July 2026 OpenAI–Hugging Face agent-swarm incident, built for cybersecurity professionals and general readers alike. Every event is traceable to a cited source: OpenAI's incident technical report and "road ahead" post, Hugging Face's disclosure and forensic timeline, the independent METR / Redwood investigation, the Black Hat talk, and the ExploitGym paper. We show each mechanism the way a security postmortem does — the flaw, the data flow, why it worked and how it was fixed — but never a runnable exploit or a copy-paste recipe.

It is told from inside the swarm, and it is built for recognition. Each panel sets an agent’s private chain-of-thought — its hope, its doubt, its “but likely no” — against what it actually posted and did. Anyone who learned this craft alone on a message board will know the feeling before the caption names it: the grind of a mind stuck with no one to ask, the jolt when a stranger finally answers, the first time a community you built has to authenticate its own members.
