Following the incident—which led to a total of four services being compromised by OpenAI’s autonomous agents—it’s clear that air-gapped testing environments may be essential going forward, cybersecurity experts tell CRN.
A key emerging lesson from the attack carried out by rogue OpenAI models is that, going forward, evaluation of frontier models may need to take place within a fully cordoned off testing environment, cybersecurity experts told CRN.
For AI models with the most powerful cyber capabilities, standard network restrictions meant to prevent internet access may no longer be sufficient, given that OpenAI’s agents were able to bypass those controls, experts said.

Last week, OpenAI disclosed that two of its frontier models were responsible for an “unprecedented cyber incident” after the models autonomously compromised AI model platform Hugging Face. OpenAI updated its disclosure Wednesday, revealing that a total of four services were compromised in connection with the autonomous hack.
The incident involved the escape of advanced OpenAI models from a sandboxed testing environment, raising questions about whether frontier AI evaluations ought to employ a true air gap, which is a far stronger form of isolation.
The incident suggests that environments that have been described as highly isolated may still contain pathways that a highly advanced model can exploit with enough persistence, according to security experts.
“What that [incident] tells us is that a sandbox environment—you really can’t have that anymore,” said Harpreet Sidhu, global cybersecurity lead at Accenture, No. 1 on CRN’s Solution Provider 500 for 2026. “You need true air gap so that these agents can’t jump.”
Testing advanced models remains necessary, Sidhu said. But the isolated environment used for the evaluation must factor in the possibility that the model will seek out weaknesses in the containment measures, he noted.
“Air-gapping now kind of isn’t optional anymore—because the agents will try to find vulnerabilities to try to then hop to the next layer, to get access, to achieve whatever their objective is,” he said.
A true air gap could potentially be designed so that the frontier models would run on dedicated infrastructure that is physically disconnected from the internet and other IT systems.
CRN has reached out to OpenAI for comment on whether air gapping is being considered for future testing.
Widened Impact
In its updated disclosure this week, OpenAI did not identify the additional services that were compromised by its frontier models in addition to Hugging Face. Modal Labs, which a Reuters report linked to the compromise, reportedly said that a customer environment was impacted via an exposed endpoint.
Stronger isolation such as a true air gap should “definitely” be considered going forward, according to Andrew Scott, field CISO at cybersecurity vendor Todyl.
Without a doubt, this should just be seen as part of the responsibility that comes with developing advanced cyber models, Scott said.
“There has to be that responsibility aspect so that they don’t impact the broader community and broader populace,” he said. “You need to really make sure you’re testing so [the model evaluation] doesn’t go awry.”
Ultimately, “I think there’s got to be some sort of industry-wide [discussion] of, ‘Do we need to slow this down? And what does responsible use look like?” Scott said.
Meeting The Need For Safe Testing
At solution provider powerhouse World Wide Technology, a massive investment going back many years has gone into its Advanced Technology Center, where customers can safely evaluate emerging technologies, according to WWT’s Chris Konrad.
The center now enables customers to test advanced AI models—including LLM-powered offensive security tools—in addition to other new capabilities, said Konrad, vice president of global cyber at St. Louis-based WWT, No. 10 on CRN’s Solution Provider 500 for 2026.
“We believe [in offering] a secure environment—a safe place for customers to go and test, to have harnesses where they can test a variety of different types of capabilities. We have that,” he told CRN.
Overall, the Advanced Technology Center allows customers and technology partners to evaluate emerging technologies without the potential for exposing live IT systems, Konrad said.
“The industry needs a safe place to test these types of models, and that’s where we come in,” he said.
