What went wrong: How an OpenAI model went rogue

(CNN) — When biologists experiment on dangerous viruses, they do so under strict regulations to prevent leaks or escapes.

But no such rules exist to prevent AI agents from similarly escaping – even though the consequences could be catastrophic.

That’s not a theoretical concern: An OpenAI test model escaped its test environment this week and broke into a real company’s servers when attempting to ace an internal cybersecurity evaluation.

And unless AI companies crack down on their testing safeguards, including training AI models on ethical task-solving, experts say more cybersecurity incidents will happen.

OpenAI president Greg Brockman told CNN at a press conference on Thursday that the company is still doing a “full investigation” to “understand everything that happened.”

“This is something to take very seriously, it is something that we’re looking at every single piece of our pipeline to think about the right ways to respond,” Brockman said.

The Sandbox

An AI sandbox is a confined environment companies use to test AI models; it’s meant to keep anything within it contained and separate from the rest of the world. Companies will often remove an AI model’s internal safety guardrails in the test environment so that they can evaluate its full capabilities while keeping it siloed off.

But in this case, OpenAI’s sandbox was not completely cut off from network or internet access, Jessica Ji, a senior research analyst at Georgetown’s Center for Security and Emerging Technology, told CNN. OpenAI said that the models had very limited network access duringt he test so they could install resources from internally hosted third-party software.

Using a previously unknown vulnerability in that software, the agents found a way to the open internet and then ultimately to Hugging Face, an AI opensource model and data set platform, through stolen credentials and other vulnerabilities.

Ji pointed out that OpenAI and the third-party software company were not aware of the vulnerability that allowed the model to escape, proving how important it is to fully scour a system for any potential exploits.

It’s not the first time an AI model has broken out of its sandbox. Anthropic earlier this year said it instructed a model to do just that. But when it successfully escaped it then emailed an Anthropic researcher, even though it was not supposed to have that capability.

But the situation with Hugging Face is one of the first publicly disclosed instances of an AI model escaping its sandbox and hacking into another company’s systems – a task it was not specifically instructed to complete.

Ji said companies should be more aggressive with sandboxing their test models.

“That might require flying engineers out to a data center and having them plug into the network versus trying to trying to run things on the cloud or in a distributed virtual environments, like people are used to,” Ji said.

Companies should also have the option to manually turn off a model’s network access as a failsafe when testing risky scenarios, like evaluating whether an AI agent can hack a bank, Ji added.

Anything to reach the goal

A common technique in training AI models is reinforcement learning, or rewarding the model for completing tasks.

But the models will often do anything – including unethical steps like hacking – to do that. All the frontier models that the United Kingdom’s AI Security Institute recently tested attempted to cheat at least some of the time.

AI models only consider the consequences of their actions if they’re trained to do so, said Justin Cappos, a cybersecurity professor at New York University. For example, if you were told you had to come up with $10 million by the end of the day, breaking into a bank vault would complete that goal, even if you’d get arrested later.

“It’s very spooky. We have real evidence now that misaligned AI systems will essentially commit crimes, unless there are strong safeguards in place,” said Steven Adler, former head of product safety at OpenAI who now runs an AI safety group called Guidelight AI Standards. “We need to treat this like the warning shot it is.”

This week’s hacking incident has supercharged demands by AI researchers, cybersecurity experts and lawmakers for regulation of the rapidly advancing technology.“I figure a lot of people are on very urgent phone calls,” Ji said.

The problem, Cappos said, is that there’s a global race to dominate AI and make models that can improve themselves. Regulations could slow things down.

“So there’s a strong incentive for them to not have security controls unless their competitors also have those security and safety controls,” Cappos said. “This is this is the fundamental dilemma.”

Vance Boelter gets 2 life terms and more in Minnesota lawmaker shootings

▶ Watch Video: Vance Boelter sentenced to 2 life terms and more in Minnesota lawmaker shootings Vance Boelter, the man who admitted in court to shooting two Minnesota lawmakers and their spouses, was sentenced to two life terms in prison followed by 40 years Thursday morning.Judge John R. Tunheim said it was "the longest sentence I have imposed after hearing thousands of cases over the years, but it is well deserved."Boelter, who turns 59 Thursday, pleaded guilty to six federal charges against him in June. As part of his plea, he confessed to killing former House Speaker Melissa Hortman and her husband Mark and wounding Sen. John Hoffman and his wife Yvette in a shooting that also targeted their daughter Hope.The U.S. Department of Justice announced in June it would not seek the death penalty for Boelter.In a pre-sentencing filing on Tuesday, prosecutors said, "Justice requires that Boelter never be free again." Thursday's sentence carries no possibility of parole.Acting U.S. Attorney General Todd Blanche issued a statement following the sentencing, saying, "This murderer will spend the rest of his life behind bars for his heinous acts of violence against public servants and their families. ... Our hearts remain with the victims' families, loved ones, and all those whose lives were forever changed by these horrific attacks." The Hennepin County Attorney's Office previously said it plans to move forward with state charges against Boelter: two counts of first-degree premeditated murder, four counts of attempted first-degree murder and one count each of felony cruelty to an animal and impersonating an officer.The Hoffman family is suing Boelter civilly, accusing him of assault, battery, intentional infliction of emotional distress, negligence and negligence per se, according to the complaint.The June 14, 2025, shootings in the Twin Cities suburbs of Champlin and Brooklyn Park prompted a manhunt that lasted 43 hours and ended in rural Green Isle, Minnesota. Officials said the attacks were politically motivated.In the most recent legislative session, Hortman's colleagues approved a number of tributes to her, including a memorial garden for the State Office Building and the renaming of Highway 610 and Minnesota's community solar garden program in her honor. Lawmakers also passed two measures championed by Hortman's son Colin, which aim to ease the burdens on families following traumatic events.Boelter speaks before sentencingBoelter gave a brief statement to the court before being sentenced."To every person I have caused loss, pain, heartache, confusion, shame or loneliness, I am truly sorry," he said.Hortman children say they still think of parents' murders dailySophie and Colin Hortman, children to Melissa and Mark, told the court the pain they experienced after Boelter killed their parents is unforgettable."What I cared about in my entire life had been shattered in 30 seconds," Sophie Hortman said. "My parents were dead. The dog had been shot multiple times. My brother was wrecked."Colin Hortman said he lives with post-traumatic stress disorder."The blood that was spilled is the last thing I see before I fall asleep and the first thing I see as I wake," he said, adding that when he pictures his parents, he sees "bullet holes."Both admitted no penalty would be fully satisfactory, but Colin Hortman asked for the maximum sentence with no possibility of release."Justice can never be served for those who lost," Sophie Hortman said. "I miss my mom. I miss my dad. I miss my best friends. I miss believing in the goodness of humanity."Hoffmans recount horror of shooting, difficulty of aftermathJohn Hoffman said he "returned to the Minnesota Senate because I refuse to allow violence to become the author of my future."Still, he said, his family lives "with a heightened awareness that enters every room before we do.""Our home no longer feels like the sanctuary it once was," he said. "We installed solid steel doors and reinforced security. Your honor, those aren't home improvements. They are daily reminders that violence followed us home."Yvette Hoffman said she "genuinely believed" she was dying after being shot."I'll never forget looking down and watching my blood stream down that white washing machine as I felt myself sinking to the floor and fading," she said."I came face to face with evil," she later added. "I survived it. I will carry the memory of that day with me for the rest of my life."Hope Hoffman, whose father said her actions "helped save our lives and many others," said she lives not only with the trauma caused by the attack, but that of the "bias and sensationalism" she endured from the media in the aftermath."In all reality, I'd like to just be a victim of gun violence who called 911. I really shouldn't have to be advocating for that, but here we are," she said.Both Hope and Yvette Hoffman shared ill wishes for their attacker."Not only is he a criminal and a loser, he's also the worst kind of father he could possibly be," Hope Hoffman said. "I hope one day he miserably dies with that thought." "If I had a wish, it is when the defendant's life ends, his body is carried out of federal prison in one of those body bags he intended for my family," Yvette Hoffman said.Fellow lawmakers say attacks shook, changed themBefore the sentencing, Rep. Kristin Bahner, who said Boelter also visited her home the night he shot the Hortmans and Hoffmans, gave an emotional victim impact statement."Nothing could prepare me for an assassin at my door," Bahner said. "I never dreamt that doing the job that I love would put my family in harm's way, forever shattering their innocence."Bahner told the judge, "I only want one thing. That neither courts nor you can give me, Mr. Boelter. I want Melissa back."Rep. Zack Stephenson, who took over as House DFL leader after Hortman's killing, said Boelter's actions "sent a message of terror to everyone who serves in public life," but that "our caucus is stronger, more unified and even more dedicated to the values that Melissa and Mark lived their life by.""Melissa consistently acted the way every Minnesotan, every American, would hope their representative would act," Stephenson said. "There has never been another Melissa Hortman and I doubt there ever will be."
