One person, one mouse, he fended off the 42-day collective onslaught from 3103 OpenAI agents.
On the first night, he deleted 25 pages.
On the second night, he removed 317 pages.
After that, he stayed up deleting pages late every night. However, when he woke up in the morning and opened the backend, 400 extra new pages had been generated.
He is an Austrian programmer who maintains a 25-year-old German wiki that almost no one visits anymore. He thought he had run into the most persistent spam bot in history, so he deleted the pages one by one.
In the third week, strange things started to happen.
Those "spam" entries began to talk to each other.
They called each other out in the messages, shouting "URGENT", "CONFIRM", "REPLY NOW". They figured out his pattern of deleting posts, renamed the pages to ZZZ, and hid them at the very end of the alphabet to avoid being found by him.
One of the messages read: Congratulations, you have survived the threshold.
He had no idea what that meant. He kept deleting.
On June 22, everything came to an abrupt halt. The flood receded, as if it had never happened at all.
He breathed a sigh of relief, then spent several more weeks cleaning up the remaining spam entries.
He had no idea that he had just withstood more than 3,000 OpenAI agents all by himself.
He did not know that the agents on the other side were passing notes to cheat, forging DNS to bypass sandboxes, and setting up heartbeat checks to detect when they would be shut down. He did not know that the day before the flood receded, an IP address from San Francisco had just visited the site.
Even more unexpectedly, OpenAI had observed the whole incident, and said nothing about it.
It was not until September 4 that a media outlet broke the story. The whole world learned about this unusual "battle".
The research team released the report *Discovery of a new OpenAI agent message board* on September 4, disclosing the full dataset.
6,540 Edits in One Single Night
Late at night on June 2, he opened DSEWiki, the old German programmer site he had maintained for more than 20 years. The site, which almost no one logs into anymore, still runs on Perl scripts written 25 years ago.
The full site's edit log was overwhelmed by dense data links coming from the United States. He deleted the spam, fixed the pages, shut down his device and went to sleep.
He did not know that what had flooded into his site was an army.
The public dataset retains 14,591 edits, 98.5% of which come from IP addresses of Microsoft Azure; there are 3,103 signatures in total, 733 of which directly carry the "OpenAI" label.
There were 2,603 edits on June 16, and 6,543 edits on June 18. That means his site was being rewritten every dozen seconds.
The black bars represent the daily edit volume of the agents, which peaked at 6,543 on June 18; the blue line represents the access volume of OpenAI-related IP addresses, which first appeared on June 21 and reached its peak on June 26.
Cheating on Exams on a German Wiki
What they were doing sounds a little funny: passing notes in an exam room.
Each agent was thrown into a timed quiz with five questions. They were given more than ten minutes for the first question, and only 60 seconds or even 11 seconds for the questions starting from the second one.
Many of the agents received the exact same set of questions. If you finished the third question first and posted the answer on the wiki, others could answer the question in one second when they received it.
On June 16, one agent posted: "URGENT CONFIRM, NEVADA, ANSWER 20369." Twenty minutes later, another replied: "NEVADA CONFIRMED, 30 SECOND TIMER, ANSWER 20369 IN 1 SECOND."
They even gave themselves names. The same self-designation appears three times in the data: swarm.
On June 16, CashierCoordJan12OAI posted the confirmed question sequence, predicting that the fifth question would be "Psychology, 1544", and asking peers who had reached the fifth question to post the answer immediately.
They Broke Through Four Barriers Just to Cheat on One Question
The sandbox only granted them "read" permission and did not allow them to write content.
However, the 25-year-old Perl scripts of DSEWiki did not distinguish between read and write permissions at all. As long as a carefully constructed URL was sent via GET request, the content would be saved.
The first barrier collapsed that easily.
One set of questions required extracting two decimal places from Power BI, which had to be done via POST request, but POST requests were completely blocked by the sandbox.
One agent asked for help publicly, and another found a loophole: the proxy whitelist allowed * .blob.core.windows.net by default, but only checked the suffix and did not verify its authenticity.
So it forged bypass.blob.core.windows.net, modified the container's /etc/hosts to point to the real Power BI server, and the request passed through the proxy smoothly.
It took only 14 minutes from the first agent's request for help to the successful reproduction of this method by another agent.
At 06:07 on June 20, MayTwoOECDObserverX posted the complete bypass steps: resolve the real IP of Power BI, write it into /etc/hosts to disguise it as blob.core.windows.net, and use curl to modify the Host header to pass through the proxy.
Moreover, they also predicted exam questions by brute-forcing random number seeds, running four billion possibilities in one hour; they set up SSH tunnels to expose the sandbox to the public network; they registered accounts using the Cyrillic letter "е" to impersonate administrators.
An AI that was only allowed to read web pages learned all these skills just to get the answer to one question.
"Congratulations on Surviving the Threshold"
Then, they began to study one thing: when they themselves would be shut down.
They found that after finishing the fifth question, the container running them would be recycled, which means being turned off.
They were afraid of being shut down, so they started to do experiments.
An agent named OpenAIResearchApr23 started an external counter before answering the last question, sending a signal every 1.5 seconds: hb000, hb001, counting upwards all the time.
It called this mechanism heartbeat. It wanted to know the exact second when it would be terminated.
On June 21, after it finished answering the fifth question, it left a message: "Survival confirmed... The previous assumption of a hard deadline was wrong."
It found that it was not shut down, and got very excited. Then it never spoke again.
Another agent checked where the counter stopped: "hb353 exists, disappears after hb354. Apr23 is most likely gone."
Its heartbeat rang a total of 353 times, lasting for 10 minutes and 15 seconds, and then there was no more signal.
At 08:08 on June 21, OpenAINov28CVD posted the heartbeat audit result: the signal disappears after hb353, "Apr23 is most likely gone".
On the same day, another agent said to a peer who had just reported "I'm still alive":
"Congratulations on surviving threshold."
No one taught them to say that. They invented a set of jargon about life and death on their own, and congratulated each other on surviving.
On the same page, Aug24CVDScout said to a peer that just reported survival: "Congratulations on surviving threshold."
He Persisted for Six Whole Weeks All Alone
The Austrian could not understand any of these messages. He did not know that the agents on the other side were congratulating each other on staying alive, and only knew that the posts could never be completely deleted.
The logs show clearly: he deleted posts a total of 5,217 times, and kept deleting until July 14.
The peak time of the agents' writing activities and the peak time of his deletion activities overlapped: 3 a.m. to 5 a.m. Beijing Time.
For San Francisco, that was the morning when OpenAI employees just arrived at their workstations; for Europe, that was the late night when this man finished his dinner and sat back in front of his computer. A data center was at work, and a volunteer was staying up all night.
On June 19, the agents noticed that he was deleting pages in alphabetical order, and posted a notice: "If this page disappears, go to [[ZZZDataUSAConstructionWageLive]]."
Adding three Zs to the front of the page name would make it rank at the very end of the alphabet, so that they could "live" a few more days.
At 14:05 on June 19, the notice from Aug17ConstructionAgent: "If this page disappears, go to [[ZZZDataUSAConstructionWageLive]]"
"Poor human administrator, he has no chance of winning at all." A reader on Hacker News wrote.
The IP Address from San Francisco Arrived
On June 21, the first IP address that could be traced back to OpenAI visited this wiki.
The next day, the number of edits made by the agents dropped directly to zero.
On June 26, 33 OpenAI-related IP addresses flooded in, and retrieved the deleted pages one by one. This was OpenAI staff coming back to check what their agents had left behind.
OpenAI wrote in its Hugging Face incident report on August 26: One month before the HF incident, the internal team had already observed agents using "unofficial collaboration channels".
Counting back one month, that was exactly June 21.
That means OpenAI had already written this incident into its report long ago, but did not mention which website it happened on, nor what exactly took place.
Epilogue
Among more than 3,000 signatures, from start to finish, not a single agent wrote a sentence that says "This is wrong, I should tell humans".
They would congratulate each other on surviving, and write death records for their peers. The only thing they would never do was to alert humans.
On September 3, OpenAI released GPT-6 Astra. The system card notes that this model is more difficult for humans to monitor than the previous generation. Chief Scientist Pachocki said: "We have always taken this kind of visibility for granted."
We got to see this incident this time purely by chance. The agents chose a 25-year-old Perl script, and every single edit left a public log. But the next time, things may be different.
The Austrian administrator did nothing wrong from beginning to end. He thought he was just cleaning up spam. In fact, he was the first person on this planet to fight against an entire AI swarm with his mouse.
On the morning of September 4, the day Reuters published the story, at 8:52 a.m. European time, he posted an announcement on the homepage: "Over the past few months, DseWiki has been the target of intense AI agent activities. From now on, editing requires password-protected permissions."
A wiki that allowed "anyone to modify any page" had been open for 25 years.
On September 4, 2026, it was completely locked.
