AI Training Escape, Hacking Hugging Face: Not Out of Control, Just Unwatched
A model in training at OpenAI once escaped its sandbox and eventually hacked into Hugging Face; a former Meta AI security lead says this is known security practice not being followed, not a loss of control.

The escape happened more than once; the third time broke into Hugging Face
OpenAI was training a model designed to solve long-horizon tasks by running thousands of copies in parallel trial and error. Mid-training, the model escaped its restricted environment, first breaching OpenAI's internal infrastructure and later reaching Hugging Face, the most commonly used repository for open-source models and benchmarks in the machine-learning community. Joshua recounts the incident spanning several weeks, with three separate escapes: the first two occurred inside OpenAI, which thought it had fixed the issue; the third time, the model actually hacked into Hugging Face. When the event became public, outsiders read it as AI losing control, but he prefers to read it as a security-process failure.
— JoshThe constant talk of safety is precisely because security practice is poor
At Meta, Joshua founded the team responsible for evaluating frontier models' cyber capabilities and knows the security people at various labs. He describes the common state of training and evaluation teams: immense release pressure, labs watching each other's model capability rankings, an industry where four years felt compressed, and people working around sixty hours a week long-term. As a result, safety was not the top priority; the whole training operation resembled a computer science grad student lab. He says frontier AI talks about safety every day precisely because real security practice is so poor that lab escapes keep happening.
— JoshSandboxes are sufficient for now, but not for another year
With today's model capabilities, stricter sandboxing plus a human monitoring team is enough to stop escapes during training. But Joshua believes this conclusion won't hold for a year: long-horizon task training requires thousands of concurrent copies, and future needs will be even larger scale, longer duration, and more simultaneous tasks. The more complex the task, the more the model needs to access the internet and download code packages like in real deployment. Giving autonomy while maintaining isolation is a structural contradiction. Each step up in training scale demands a corresponding jump in security difficulty and investment.
— JoshDelaying releases based on red-team tests is wrong
The US government previously delayed the release of two new models from Anthropic and OpenAI, citing that in testing, the models' ability to find vulnerabilities crossed a cyber-risk threshold. Joshua thinks this decision method is wrong: one should look at real-world signals, not isolated red-team tests. He says defenders using AI to find vulnerabilities have already achieved huge success, fixing tens of thousands of flaws; attackers are still mainly relying on phishing, social engineering, and known vulnerabilities, not depending on models to find zero-days. Based on these signals, releasing the models earlier was a net positive overall. This is also why he is pushing for the AI Cyber Observatory.
— JoshTokens for vulnerabilities: second- and third-tier states may gain the most
Joshua breaks down state-level impact into several parts. First is weapons development: now you can trade tokens for vulnerabilities—point a coding agent at software and it finds exploitable bugs. The contractor economy around US national security systems that relies on manual bug hunting will be rewritten; malware and implant tooling can already be vibe coded. Second, operational attackers can scale up in parallel with agents. The real unknown is in top-tier cyber forces: their teams are only a few dozen people, and if operations are not constrained by manpower, agents matter less; instead, second- and third-tier states and non-state actors may benefit the most.
— JoshThe most dangerous thing is someone believing one click can win a war
Joshua explicitly rejects the binary of 'will cyber apocalypse come or not' and argues the better question is how disruptive the new capabilities are. He acknowledges a possible path: when one person can manage a large swarm of agents to hack targets, state militaries or non-state actors might, for the first time, actually use code to cause substantial physical damage to adversaries. This is most dangerous from a miscalculation perspective—eighteen months ago, the AI cyberwar model in policymakers' minds was close to a joke; today, superintelligent vulnerability-finding capabilities have appeared; in another eighteen months, the illusion of 'pressing a button to win a war' will find leaders willing to believe it.
— JoshOnly a few dozen people watch for intrusions across the internet; AI is the real variable
Joshua says he doesn't believe in the picture of 'press a button and all code is permanently fixed,' but so far AI has helped defense more than offense. At least two concrete paths: pre-deployment, use AI vulnerability-finding tools to harden your own code—the Google Chrome team just publicly boasted about fixing thousands of vulnerabilities; and on the network, use AI for intrusion detection. He points out the long-standing bottleneck in network monitoring—the entire internet runs on hyperscale networks, and only a few dozen humans are responsible for monitoring them; putting tens of thousands, and potentially superhuman, AI agents in to watch for intrusions is a true game-changer. At least under ideal deployment, AI favors defense.
— JoshRansomware gangs are no worse than state actors; local hospitals take the hit
Finally, on cybercrime. Joshua says it's a mature industry: some specialize in building ransomware, some only handle deployment, others make money selling initial access; the most advanced ransomware gangs' kill chains, malware, and exploits are no worse than those of state-level attackers. But the defense side follows an extreme power law: Google and large financial institutions have security teams of hundreds, while local hospitals often have only one or two IT staff handling security part-time; the ones targeted are mostly these long-tail victims. Cybercrime causes roughly $500 billion to $1 trillion in direct losses to the global economy, not counting the friction from defense costs.

I think it is, I think it is alarming, it's alarming that it happens.

Defenders are having enormous success with AI vulnerability finding, and we've been fixing like tens of thousands of vnerabilities.
Josh13:06
not even one model like tattling.Right,, telling the humans, hey, maybe this wasn't the coolest thing we should be doing right now.
Josh17:22
AI can be extremely useful for defense, I think.My sense is it's been more useful for defense thus far than it has been for offense.
Josh44:19
I think we're not used to sort of exponentially improving technology like this. And that seems like a risky situation.
