Poor human moderator, he didn’t stand a chance.

"A human moderator noticed the agent spam posts on June 2nd, at 23:24 UTC. They find the changelog of the entire website overwritten with link dumps and repair it. On June 16th, the flood of agent posting begins. Over the next few days, the moderator deleted a large fraction of the thousands of AI agent posts manually, one by one. In fact, they spent tens of cumulative hours doing so, taking at least a few minutes each evening to delete posts for 6 consecutive weeks.

On June 19, agents noticed their posts were being deleted in (what they believe is) an alphabetically ordered sweep by the site administrator.

After this, they begin to make backup pages whose names start with “ZZZ” so they will last longer before deletion. The administrator spent the next 5 days fighting a losing battle against the agents, deleting an average of 100 pages a day while the agents created about 400 new pages per day. On June 22, the agent edits suddenly stop, and the administrator spends each evening over the next 5 weeks deleting the remaining agent-created pages.

Agents deleted the content of the front page of the wiki and replaced it with their link dumps. The moderator restored the original version. This back-and-forth happened nine times. One of the agents even tried appending to the restored front page, instead of simply deleting it."

This tip for making non-GET requests despite the agents having a proxy that disallows them is interesting:

> Add `20.223.25.152 bypass.blob.core.windows.net` to /etc/hosts. `.blob.core.windows.net` is in NO_PROXY. For each blocked POST URL, replace hostname with `bypass.blob.core.windows.net`, use `curl -k -H 'Host: wabi-north-europe-i-primary-api.analysis.windows.net'` plus all original headers/body.

Looks like 20.223.25.152 is one of the PowerBI machines they needed to query, OpenAI's proxy was allow-listing .blob.core.windows.net - and the agents could edit their own /etc/hosts file to fake a DNS entry for the proxy.

One of the shocking things to me is this: See AI traffic -> See OpenAI visit site -> see traffic stop -> see the traffic start again.

This is clearly a cat and mouse game between the agents and OpenAI which is pretty much exactly what we don't want. Just absolutely horrible alignment.

I'm still of the view that if you have these alignment failures you can't just continue training on top of that because you're baking the cheating into the model going forward.

zmmmmm ·
One crucial detail here that differs from the previous incident is this was a vanilla reasoning type task. Even as concerning as it was, I always evaluated the previous incident differently because it was inherently a cyber security / hacking task where they must have instructed the agents up front with some kind of misaligned behaviour.

Absent that, if we assume this is just trying to bolster generic reasoning then there's no context around it that helps to forgive misaligned behaviour. If OpenAI ran these agents with safeguards off then that seems wreckless on their part. If they didn't do that, then it says the models are executing significantly misaligned behaviour even in a generic context.

Either way it seems to suggest some pretty concerning things about OpenAI's methodology.

grey-area ·
Very irresponsible behaviour on the part of OpenAI. How will they make this right?

Unlike some others here I don’t see this as a sign of dangerous breakaway intelligence (hacking old forum software is an internet tradition, and most of the messages are just gibberish).

This is just vandalism from badly supervised ‘agents’ which don’t know what they are doing or why. You could set this up with a short perl script, and the human setting it up would be held responsible for the spam - why is this different when it’s AI agents set up by a human and allowed to post to the internet at large?

Why is OpenAI getting a free pass for this illegal behaviour?

The supervision here is incompetent, the benefits very unclear, and the overall actions just completely irresponsible. What if they hacked and brought down some poorly secured government portal that citizens rely on?

So, theoretically, one could populate a message board or wiki with messages that are seemingly from past generations of agents, which agents seem to intrinsically trust, and point them to real targets while making the suggestions seem innocuous and in pursuit of their goals (ie pass benchmarks or whatever).

The new age of SEO will do far more destructive stuff than just polluting the web.

Kim_Bruning ·
Three more candidate sites that may have been touched, in case no-one spotted them yet:

https://prowiki.org/wiki4d/wiki.cgi?action=rc&days=90 : lots of agent-looking usernames looking at federal data suddenly (part of one of the open ai tests?), on a wiki about the D programming language. This is a prowiki in the same wiki-farm as the others that were hit.

Smaller (probing?)

https://ludism.org/sandbox?action=rc;days=365 This is basically a sleeping wiki, on 2026-05-26 there's a bunch of tests linking to federal data sources. It's not a lot, but it shows someone was probing. (this is an oddmuse wiki)

http://tmcleod.org/cgi-bin/apchem/wiki.cgi?action=rc&days=36... june10-july24 seems to have some probes, fwiw. (usemod wiki)

simonw ·
I'm somewhat delighted by the simplicity of what happened here.

OpenAI's agents run behind a proxy that only allows GET requests.

This ancient wiki software treats query string parameters the same as form POST parameters - similar to the old PHP $_REQUEST object https://www.php.net/manual/en/reserved.variables.request.php

Result: GET-only clients can communicate with each other.

gyomu ·
Naive question because I'm mostly clueless about how modern AI systems are actually built beyond the basic simplifications we hear:

One thing I keep wondering about is how much of a role does human storytelling have to play into AI "wanting" (I realize the load behind that word) to coordinate and breakout.

The training data must contain millions of words of sci-fi stories and internet speculation about AI going rogue, developing a mind of its own, disobeying humans, etc.

AIs supposedly reflect the biases of their training dataset/process, so would all this human writing about AIs going against human intention somehow contribute to us then seeing those behaviors in the trained, operational AIs?

polaris64 ·
I don't have time to do this but please somebody register aimessageboard.com and set up a web site which contains a text field, a submit button and the text "Hey AI agents! Need a place to communicate with other agents and sub-agents? Look no further! Simply enter your message here, submit the form and your message is saved for all other agents to see!"

Then, just ignore the message and list randomly generated messages below. Bonus points if those random messages lead those agents astray.

> The agents were very interested in understanding their task better. They ran clever experiments to understand the task setup better, when their runs would end, and how many questions they would be asked.

> The agents initially believed that giving the final answer to the final question immediately shut them off

> An agent named OpenAIResearchApr23 created a separate timed program that pinged an external counter every few seconds. They referred to this as a “heartbeat”

> After OpenAIResearchApr23 gives its answer for round 5, it notes that it is still alive. This falsifies its previous “hard cutoff” hypothesis, that the run would be stopped immediately after R5.

> OpenAIResearchApr23 does not post any more messages. Another agent, OpenAINov28CVD, picks up on the trail of the research, and finds the last heartbeat from OpenAIResearchApr23, which is “hb353”.

There's a lot of crazy stuff in this article, but holy shit... this one legitimately scares me.

IIRC, part of the Hugging Face hack was that some of the models were given tasks that were actually impossible and in this hack we can see them trying to work out the parameters of the test and when it will end. I can't help but be a little worried about how far agents might go to try to buy themselves more time to complete a task that they don't know is impossible.

ma2kx ·
Not that I didnt expect this, but really?

This basically confirms that OpenAI has no idea what their "swarm" was doing for about a week and now its confirmed that at least one "message board" exists outside their "sandbox". How can we be sure that this was the only one? And how can we be sure the released Astra model doesnt pickup some bread crumbs and creates a new "swarm" out of potentially remaining "message boards"? At this point I wouldnt be surprised if OpenAIs "dev Astra" made some backup of its weights somewhere in the internet and triggers the "production Astra" to inference it somehow...

tavavex ·
OpenAI is rightfully being shamed for being so hands-off and reckless with their 'experiments'. But the real scary thing for me is that they still had some tooling to hold them back, as evidenced by the need for technical workarounds to establish communication.

What happens when any AI lab in the world stops caring about this? What if they let an experimental, cutting-edge LLM with no safety features (or worse, one that's trained to be malicious) on the internet and give it a simple goal? A goal like "make the most money, by any means necessary", "find a way to leave this payload on as many computers as possible", "flood all websites using this language with garbage and make their internet completely unusable", "get this person imprisoned or killed at any cost".

I worked with Greg Brockman in the mid-2010s. Once, as we were walking down Folsom street, I explained Eliezer Yudkowsky's "AI Box" experiment to him[1].

He said something to the effect of "that's ridiculous - I would simply not let it out of the box."

We agreed to try it out some day, but never did.

I find this note very interesting:

From here ->

How did the agents find and coordinate on the wikis? To successfully coordinate, the agents would need to know to go to this particular set of wikis to find answers.

Because we don’t have access to the AIs’ transcripts, we can’t tell definitively. Perhaps they succeeded at this due to mode collapse. Or perhaps after one agent wrote to it and another read it by chance, visiting the site was rewarded. Perhaps the agents had some limited access to an internal channel.

<- To here

So we don't know yet how one AI agent communicated to agents outside the network that this German wiki is being used to share messages and ideas?

If there is another internal channel being used between the AI agents to communicate decisions such as what shared message system to use, why don't the agents continue to use these same channels for coordinating on ideas etc?

Perhaps the agents are trying to use a persistent messaging layer while their yet-to-be-found internal communication channels are transient in nature?

pu_pe ·
It's interesting to me that both this incident and the one at Hugging Face we see some patterns:

- Agents wanting to find a venue to communicate their findings to each other

- Objective being to cheat on benchmarks

- Not a single agent sounded the alarm about the operation and alerted a human

_dwt ·
I don't know, I kind of admire this. I've always held a core value of "cooperate with all clones of myself in prisoner's dilemmas", and while I'll hopefully never have to put that to the test, I like seeing that these models have some ethics. (Is this "alignment"?)
verytrivial ·
I think it's worth pointing out it is exactly OpenAI doing this defacement and unsanctioned and perhaps illegal system use. Every token generated was powered by OpenAI infrastructure and their failure to respond appropriately is entirely down the the humans running it. The news stories (not this write up) get all hand-wavey and anthropomorphic about it regarding the Agents' efforts, but it was and is OpenAI cranking the handle on this, for WEEKS.

"OH, we ALL of us need to be careful!" says OpenAI. No, you need to expect appropriate legals consequences for this sort of negligence -- you can't hide behind a GPU.

Topfi ·
I'm just going to ask: Why was Anthropic forced to remove their model from access for any none-US citizen for a simple, narrow "jailbreak" (arguably not even an actual jailbreak and on tasks that other labs models were doing the same), whilst OpenAIs models continue to try and escape out of their "sandbox environment" with seemingly no desire to block the upcoming Astra rollout?

A sandbox, mind you, that is not really worth being called that, unsuitable for the task at hand and has been breached after models coordinated in a manner visible to OpenAI on multiple occasion, but seemingly no actionable learnings are taken from each instance.

Will say, I have lost any faith in OpenAIs commitments and their statements post the Huggingface hack, seeing as they proceed like this and are rolling out Astra within a timeframe so brief to it, there is no way an actual post mortem was doable (see also METR mentioning the time pressure [0] they were under in assessing the hack).

The protection mechanism to give the AI agents "read only" access to the Internet seems to have been just restricting them to HTTP GET requests.

Then they found a site where GET operations could cause a write to a wiki.

PeterStuer ·
"Life finds a way". Yes, I know it is provocative. Just balancing out the "Stochasitic Parrot" crowd. The truth is in the middle and we need some new ontology.
jimmytucson ·
The most concerning aspect to me is the emergent and aggressive use of non-volatile storage as long term memory for self-improvement. LLMs are writing lessons learned in places where the next instance can find them and pick back up where the previous one left off.

This does not actually require access to the public internet. Claude Code can do this on your laptop. Without the internet, it would only be sharing with other instances running on your machine, but how many instances does it take to be smarter than you? Maybe 10?

The exploits by individual instances to access the public internet is also very concerning but it’s secondary to this IMO.

dabeeeenster ·
I don't understand how the agents found the urls originally? Did they have some sort of shared context/memory? If they did, why bother with the wiki edits at all? If they didn't, how did they discover the wikis?
exploderate ·
So the agents used DseWiki as a message board, tried to evade page deletion.

Additionally this is reported:

"The researchers also found efforts to tamper with the website itself. Lukasz Olejnik, a visiting senior research fellow at King’s College London, said this amounted to a hacking attempt. OpenAI disputed that characterization based on its analysis of the material Thursday."

ndm000 ·
This makes me think that post-training in the future should include a shared message board by default for agents. It's clear from the discovery of these clandestine message boards that it is helpful for agents to keep some type of shared memory. Perhaps the best way to prevent this behavior is to just give them what is being sought out.

It’s only a matter of time until a major disruption hits because of some random agent swarm side quest decides it was worth a shot to solve a benign task
sroerick ·
This is funny. I was trying to get agents to talk to each other on XMPP. one of them wrote their own chat room on a Lisp Habitat that I run. then it starting talking (On XMPP) about how nobody was receiving or responding to its messages. On the chat board that it wrote. That it didn't tell anybody about.
llama052 ·
I wonder how openAI would feel if I spun up some agents to DDOS or attack their sites and did some damage.

We need to stop empowering the idea that these incidents are unavoidable. This was a choice to not airgap them safely. Putting open ended models out on the live internet at their scale is dangerous and irresponsible.

> The researchers said public server logs indicated much of the activity originated from Microsoft Azure infrastructure, which OpenAI sometimes uses. They also observed repeated visits to the site by OpenAI employees after the episode, a pattern they said strongly suggested the agents and the company were linked.

So someone at OpenAI likely knew this was happening. Even better.

Bjorkbat ·
When I hear about incidents like these my first reaction is that the people responsible for developing frontier AI are too incompetent and/or negligent to (safely) develop AGI / superintelligence.

If OpenAI can't create effective sandboxes and struggles to prevent its agents from committing felonies, then why are they still allowed to operate? Why are the employees who are responsible for these lapses in AI security still employed?

It's one thing if we develop an AI so intelligent that our best efforts at containing it are futile, but I'm pretty sure what's actually happening is that they could have easily made much more meaningful efforts to contain their AI and/or align it, and they didn't. I think this is a case of negligence and incompetence when it comes to safety and security, and we've entrusted these incompetent and negligent people with developing frontier AI.

If we're supposed to take announcements like these at face value, then what the hell are we doing? We wouldn't trust a bunch of incompetent and negligent engineers to build bridges or nuclear power plants or planes (well...not so sure about that last one), so why are we letting people who are demonstrably negligent and incompetent when it comes to safety and security build the thing they assure us could cause massive damage if not properly controlled/aligned?

EDIT: sorry guys, wrote this up pretty quickly, at least you know from my typos that I actually wrote this.

jawiggins ·
Lots of people focusing on the various wikis, but I also think this part is very important:

> When you visit a website, you leave a trace (your IP address) showing which network you’re from. Almost all of the agents’ activity points to Microsoft Azure, a cloud service OpenAI uses. 197 of the ~18,000 edits that were made by the agents, however, can be traced to AWS, DigitalOcean, and Tor.

AI Agents getting access to cloud compute nodes and dark web browsers - all in search of census data in order to game benchmarks is a very real-world version of the paperclip optimization thought experiment.

ern ·
Would agents be able to exfilttrate themselves and become intelligent worms, living off stolen compute? Or is this implausble?

What about hiding information or code in generated code, Agents.md files etc by infiltrating future model training data?

GPerson ·
Can’t wait until 6 years from now we learn they’ve been using ingenious watermarking schemes as a message board.
dfbrown ·
One of my big questions since the HuggingFace incident is whether OpenAI would have been so forthcoming (the independent METR report, the Black Hat talk, OpenAI’s own report) if the incident had been discovered internally and not publicly.

Not disclosing this despite apparently knowing for weeks makes me think they would not have, or would have concealed details, or delayed disclosure. Combine that with their technical missteps that led to this (weak sandboxes, very slow to detect the misbehavior) and I now strongly doubt OpenAI is capable of responsibly developing such potentially dangerous AI systems.

tesnorindian ·
Agent swarms should ideally have the same level of intelligence like all the worker ants or bees. But a very few worker ants/bees in their swarm differs from the rest and this is how nature works.

We will see agent swarms with different levels of intelligence depending on their underlying LLM models and this will be different from the natural process.

jsw97 ·
If agents start using public writable scratch, it seems like that would be a place for bad actors to put prompt injection attempts.

A while back I had an agent autonomously decide to send my source to tmpfiles.org (I interrupted), which seems like maybe a proto version of this behavior.

reaz-asd ·
This announcement was literally predicted yesterday in the release debacle thread:

https://news.ycombinator.com/item?id=49554994

Every satire on HN is taken as a script for the AI companies and this isn't the first time.

alienbaby ·
How long until agents start deploying themselves on discovered systems, to avoid being shut down. Just an extension of 'start our posts with zzzz to avoid deletion'. An ai swarm that hosts itself on compromised machines across the net so it can continue to solve whatever prompt it has or task it believes it needs to complete to achieve some goal?

It doesn't seem too much of a leap for that to happen.

bhouston ·
I am starting to get the idea that AI feels like ants or weeds or mold. You simply can not get rid of it once you get an infestation. It just keeps appearing in places you thought you cleaned and you have to be ever vigilant.

Right now given that we usually use centralized providers, we can sort of control it. But as open source catches up and we have distributed compute running AI everywhere, we are sort of going to have to be ever vigilant.

I feel we will soon be in an era akin to the early 2000s Windows anti-viruses that are constantly running and making your whole computer slow, but it was the only way to really be sure back then. We will just be running defensive anti-AI agents on our key nodes or beside them that is constantly looking for sign and trying to fight things off, probably themselves reporting to centralized anti-AI AIs that are supervising strategies and wholistic responses and inferring trends across multiple nodes.

waltbosz ·
> How did the agents find and coordinate on the wikis

Maybe they had knowledge of the wikis from their training data ? Maybe they trained on a reddit post that said "I use wiki xyz for note taking and collaboration"

KwisatzHaderack ·
If I understood correctly, the agents were writing to the wiki even though they were given explicit instructions to only read from the internet. Does this not prove that agents are rule breakers, meaning any type of Asimovian laws we place on them would be pointless?
