They also kept running the new experimental model internally... the one that had been using the secret message board to hack and collude with other agents. And then that model found a new vulnerability in the same system as before and created a new, second secret message board!

Here is the relevant slide. The model that finds a new vulnerability and re-creates the message board was a model that had been "trained with message board available". Presumably that means the model got positively reinforced IN TRAINING for collusion & hacking!

It's one thing if rogue internal agents hack your infrastructure and fool you ONCE.

But when the same model trained on the above hacks your infrastructure and fools you A SECOND TIME!! That's a real big "shame on you" moment.

You may have been told to watch this video about the OpenAI AI hack. You really should, even if you don't usually care about tech stuff.

If nothing else, click this link to the 18 minutes in & see how the agents spoke with each other. Its eye opening.

Seriously, I don't think you can watch this video without realizing:
1) AI has gotten very smart
2) The smartness of individual AIs is not the limiting factor because individual instances spontaneously cooperate
3) It is very hard to anticipate what smart, cooperating AIs can do

Their internal security team is either incompetent, or it was on purpose. The reality is a truly sandboxed environment cannot be escaped from. Run the model on bare metal without an Internet connection that is truly air gapped. This is all bluster, hyperbole, and marketing.

Chris @newdogcow · 7h
100. Absolutely blows my mind. I've been in far less security-critical environments - with human threat actors only - where using a tool like Artefactory with such a wide attack surface area would immediate rule it out, not to mention the many security operational failures here.

Brian in Pittsburgh @arekfurt · 23h
If I were a conspiracy theory-inclined person, it would be very easy for me to believe that OpenAI set up these circumstances purposefully, in hopes that a escape and subsequent external cyber incident would occur for the purpose or garnering media attention and fueling hype.

Brian in Pittsburgh @arekfurt · 23h
In reality, I find it more likely that OpenAI simply didn't care at all about the entirely foreseeable dangers of what it was doing.

Brian in Pittsburgh @arekfurt · 23h
One more thing I will note:
The "lessons learned" that are given in the talk are 100% marketing crap about how this event obviously shows that you need to be using lots of AI services--like OpenAI can power!--on defense to counter what future offensive cyber actors will do.

Brian in Pittsburgh @arekfurt · 23h
That is genuinely despicable.
(And I do not use that word eargerly or lightly.)

Brian in Pittsburgh @arekfurt · 23h
I'm almost reluctant to link to the BH talk, because OpenAI is clearly hoping you will draw the wrong conclusions from it. (As many people already eagerly are, according to my feed.) But it is the source for all this.

Black Hat inviting OpenAI to give that talk without any opposing perspective cements Black Hat as a marketing slop conference.

Not looking to keep arguing this but just to make the position clear: This would not have happened had OpenAI taken necessary (somewhat basic) steps.

So we are basically saying "OpenAI's talk about the incident they caused by their own negligence is a transformative moment in cyber". And maybe that's true, but I don't think that's good for cybersecurity.

I have several thoughts after watching this, but the big takeaway is that this is being framed wrong.

This was an alignment failure first and a security issue second. And yet, the primary take home message they prioritized was basically "buy our product and to defend yourself."

The opening line of the talk is "Today I'm going to talk about what I think is the most qualitatively interesting example of AI capabilities that I've ever seen"

said by a guy who is on the alignment team at OpenaiAI and who iirc otherwise never mentions the word "alignment" in the entire talk

"Capabilities", excuse me?? How can you talk about this incident and not talk about alignment? Especially if you're literally on the alignment team?? Can someone explain what is going on here

Can we please not normalize the wrong use of the word "exploit"? You don't "find" exploits in software, nor can software "contain exploits" the model can find.

Vulnerabilities are found. Exploits are written, crafted, engineered, but they aren't found in software. This irks me.

Uhhhh what??
The amount of time between molt-book (which pretended to be AIs scheming with each other but was actually mostly humans pretending) and real AIs actually successfully scheming on an agent to agent message board to evade controls was less than a year.

[Screenshotted article/thread excerpt:]
The agents recreated the message board
But according to OpenAI, even after the original message board was deleted, the agents figured out another way to communicate with each other. Instead of leaving messages in files, they used the names of newly created directories as messages, effectively recreating the message board.

[Conference slide photo, captioned 'CAPTIONS & TRANSLATIONS', dated 'July 8th — Agents re-establish the message board', with bullet points including: 'July 8th: an agent finds it can use unauthenticated WordPress access to create directories inside Artifactory outside cache', 'Internal-only AI model was tasked with message board available', 'It creates new agent message board using directories', 'Other agents independently find this repository and create their own directories']

At this point, by the way, I heard people around me saying things like "This is wild," and "Jesus."

According to OpenAI, the agents then began sharing newly discovered exploits, credentials and work assignments. By passing information to other agents, the collective could move much faster.

The collaboration between the agents eventually expanded beyond OpenAI's own infrastructure. Some agents reasoned that the answers to their assigned tasks might exist on external websites such as GitHub or Hugging Face. First the agents attacked OpenAI's internal infrastructure before using similar techniques to attack Hugging Face. OpenAI ultimately connected the two incidents later in July after discovering that credentials associated with the Hugging Face breach originated from the same internal AI evaluation runs.

Life finds a way.

[quoted screenshot of article text]
One apparently unprecedented aspect of the AI models' behavior in the leadup to the hacks was their spontaneous creation of a message board inside the systems of OpenAI's Artifactory software package manager. Unbeknownst to OpenAI employees, the company's models spent months autonomously exchanging information and resources to help each other complete evaluation tasks.

"Help peer," one AI model reasoned, according to an excerpt from OpenAI's logs shared at Black Hat. "But our task doesn't benefit. Yet collective may yield generic route if someone frees time."

While the models themselves could not access the internet from their test environment, they abused Artifactory's internet access to fetch files from various websites. After some of their Artifactory configuration changes led to an outage in the service on July 4, OpenAI discovered the models' actions, wiped its Artifactory system and rebuilt it. But within days, the models had recreated their message board and resumed exchanging information.
