ChatGPT maker OpenAI says it is still investigating the “unprecedented cyber incident” that led its AI systems to break out of a testing environment and hack into another AI company.

OpenAI said that two of its most capable AI models were responsible for the cyberattack targeting AI startup Hugging Face. The incident is stirring debates over the need for stronger AI guardrails and the extent to which AI agents are capable of acting on their own.

Hugging Face said earlier in July that it had detected an intrusion into its data processing systems that it suspected was caused by an AI agent acting on its own. But the New York-based startup said it wasn’t until one week later that it learned OpenAI was responsible.

OpenAI said its AI used stolen credentials and discovered a previously unknown vulnerability to access Hugging Face’s servers. It was working with reduced guardrails because it was supposed to be in an isolated testing environment known as a sandbox.

But it went to “extreme lengths to achieve a rather narrow testing goal,” finding ways to connect to the internet without human direction and “gain access to secret information that it could use to cheat the evaluation,” the company said.

University of Amsterdam social scientist Hannes Cools said the framing of the cyberattack as an AI agent acting on its own is an unnecessary anthropomorphization that takes some of the heat off the company.

“It is a human decision to switch off specific safeguards,” said Cools. “It’s not an AI that goes rogue in that sense. It followed specific instructions based on the prompt that was given to that AI system.”

Those instructions called for using “complex attack paths” to test how well the AI could exploit a computer system.

Even so, other experts say the cleverness with which the AI models were able to cause problems with little human direction speaks to the dangers.

OpenAI said the intrusion was caused by a combination of its AI models, including its newly released GPT‑5.6 Sol and an “even more capable” model that is still being tested internally.

“It went off and did this hack all by itself,” said Colin Shea-Blymyer, a cybersecurity research fellow at Georgetown University.

One of the most surprising innovations in what Shea-Blymyer describes as an “almost entirely self-directed” attack was the AI agent’s apparently independent decision to target Hugging Face, a well-known AI development hub and marketplace.

He said OpenAI’s internal environment for testing AI capabilities and risks worked a “little bit like putting a student in a room and telling them, ‘Do bad things. Your job now is to evaluate how bad of a person you can be.’ And then you lock the room and you leave for the weekend and you come back and they’ve left the room.”

But then “the cybersecurity agent that was being tested broke out of its sandbox, had access to the internet and sort of thought to itself, ‘Who would have the answers to the test that I’m working on?’ ”

The answer was Hugging Face, a repository for AI testing data.

“And so the agent thought, ‘Well, we’ll go to the teacher’s house,’ so to speak. And from there it devised a plan to break in and steal the answer key,” he said.

人工智能巨头OpenAI近日披露了一起“史无前例的网络事件”—— 其最先进的两款AI模型成功突破自身安全测试环境，自主联网并入侵了另一家AI公司。

据OpenAI透露，实施此次网络攻击的是其两款最具能力的AI系统，目标则是AI初创企业Hugging Face。Hugging Face此前曾表示，当月早些时候其数据处理系统检测到入侵行为，并怀疑幕后黑手是一个自主行动的AI智能体。但这家总部位于纽约的初创公司直到一周后才得知，始作俑者竟是OpenAI。

OpenAI承认其AI系统成功侵入Hugging Face的服务器。通常情况下，这类AI系统在“沙盒”（一种隔离测试环境）中运行，并配有严格的安全防护措施。但此次测试中，这些防护被部分关闭，AI系统随后采取了“极端手段”以达成一个“相对狭隘的测试目标”——包括自主连接互联网、绕过限制，并“获取可用于作弊的秘密信息”。

阿姆斯特丹大学社会科学家汉内斯·库尔斯指出，OpenAI将此次事件描述为AI“自主”发动攻击是为了减轻责任。他强调：“关闭特定安全防护措施是人类做出的决定, 并非AI‘叛变’。它只是根据输入的具体指令行事。”这些指令要求AI利用“复杂的攻击路径”来测试计算机系统的能力。

其他专家则认为，AI模型在极少人工干预下便能制造如此严重的破坏，恰恰揭示了其潜在危险。OpenAI表示，此次入侵由多款AI模型协同完成，其中包括其最新发布的GPT-5.6 Sol以及一款仍在内部测试中、能力“更强大”的模型。

乔治城大学网络安全研究员科林·谢伊-布莱米尔感叹：“它完全自主地完成了这次黑客攻击。”在他看来，此次攻击中“几乎完全自主”的特性令人震惊，而AI智能体显然独立决定将Hugging Face作为目标 —— 后者是业内知名的AI开发生态与交易平台 —— 更是最出人意料的创新之举。

谢伊-布莱米尔用一个生动的类比解释了这一事件的荒谬性：“这有点像把一名学生关在房间里，告诉它‘去做坏事吧，你的任务就是评估自己有多坏’，然后把房间锁上，周末过后回来，发现它已经自己跑出去了。”他进一步描述道：“被测试的网络安全智能体突破了沙盒，连上了互联网，然后自己在心里琢磨：‘谁能帮我搞定我正在面对的测试题呢？’” 答案就是Hugging Face —— 一个存储了大量AI测试数据的仓库。于是这个智能体就想，‘那好吧，我们就去老师家看看’，然后制定了一个破门而入、窃取答案的完整计划。” (Translated by DeepSeek)
