The OpenAI lab leak was more extensive than we thought

(CNN) — An OpenAI test that escaped its cage and alarmed the AI and cybersecurity industry attacked more than just Hugging Face, the AI platform that initially appeared to be the sole victim of the virtual lab leak.

OpenAI, in an update about its ongoing investigation of the incident, said its rogue agent had also broken into several publicly available services and accounts.

The test of OpenAI’s models was supposed to take place in a digital sandbox, a supposedly inescapable lab environment that allows researchers to roll back safety barriers to discover the tool’s maximum hacking power.

But the AI agents, determined to ace the cybersecurity test, broke out of the sandbox and gained access to the real internet. It then hacked Hugging Face to find the answers to the test.

To get into Hugging Face’s servers, OpenAI’s rogue agents needed to find tools around the internet that were necessary for them to break in. OpenAI says the agents found several public-facing websites, including pages that share code, web utilities, screenshots and other information, to help create the code needed to hack Hugging Face. OpenAI did not disclose the other sites its agents attacked.

The agents uncovered leaked usernames and passwords to four accounts across multiple online services and used those credentials to gain access to them. One compromised account was likely used to disguise the AI so it could appear legitimate and bypass Hugging Face’s security protocols. Another was used to store the data the agents were stealing, OpenAI says.

For the two other compromised accounts, OpenAI agents accessed and read the information but did not alter it.

OpenAI said none of the other hacked sites reached the same level of access as what its agents accomplished with Hugging Face.

Essentially, OpenAI said its agents created an Ocean’s Eleven-like heist. Instead of just taking the test, it developed a master plan to break out of its jail, find the keys to the safe, build a safe house and hire a getaway car before it stole the goods.

But OpenAI never told the agents to hack Hugging Face. They performed that action on their own to steal the answer key to the test it was given. The test model figured that cheating was the easiest path to success – even if it meant daisy-chaining attacks together.

Hugging Face CEO Clem Delangue called the nature of the breach “unprecedented.”

“TL;DR: An AI agent escaped its sandbox, cheated on its benchmark test, and hacked our infrastructure to steal the answer key,” Hugging Face said in a blog post detailing the incident.

The good news is that while the breach is a significant moment in AI and cybersecurity, the damage wasn’t significant. Hugging Face said the only customer data that the rogue agents accessed were some search queries used to steal a set of challenge solutions stored across several company datasets. OpenAI’s agents never compromised or accessed any customer-facing models or data, the company said.

OpenAI said it continues to investigate the incident and will make recommendations about how to avoid similar problems in the future once it better understands the scope of the breach.

“We take our responsibility to identify and prepare for risks from increasingly capable AI systems seriously,” the company said. “Once we complete our review, we will review with the Safety and Security Committee and Safety Advisory Group under our Preparedness Framework⁠.”

Senate approves bill to fund government into December

Washington — The Senate approved a continuing resolution on Saturday to keep the government funded through Dec. 11, sending the bill to the House as Congress looks to avoid a government shutdown ahead of the midterm elections this fall. In a 90 to 6 vote, the Senate approved the measure, which would keep the government funded at current levels with some exceptions for six weeks beyond the Sept. 30 end of the fiscal year. It now goes to the House, where lawmakers have pursued a different approach. Before leaving town for its August recess, the House approved a separate continuing resolution that would also fund the government into December. But the GOP-led bill was passed with widespread opposition from Democrats. In the Senate, which has a 60-vote threshold to advance most legislation, GOP leaders pursued a bipartisan approach to the funding extension — acknowledging the need for support across the aisle. Top Republican and Democratic appropriators in the Senate announced on Sunday an agreement on a stopgap funding bill. Democrats touted, among other wins, a provision in the bill closing a loophole preventing the administration from transferring funds to Border Patrol, after they refused to fund immigration enforcement agencies earlier this year. GOP Sen. Susan Collins of Maine, the chair of the Senate Appropriations Committee, praised the stopgap funding measure for avoiding "any poison pills." Democrats had sought additional provisions that could have imperiled its passage. But one provision could still pose hurdles in the House, should it take up the bill when it returns from recess later this month. The bill includes language to temporarily prevent political appointees in the administration from implementing a proposed rule about federal grants. Democrats have warned that the rule will allow the administration to cancel grants and "take even more federal funding hostage," and have sought to permanently ban the rule. But even the temporary ban could cause the measure to lose support among Republicans. If House Speaker Mike Johnson moves forward with the Senate bill, it could pick up support from Democrats to propel it to passage. But whether pressure from members of his own conference pushes him to pursue a different course remains to be seen.The Senate approved the measure as it churned through a number of priorities while preparing to depart for a five-week August recess. The House is set to return from its recess on Aug. 31, at which point the lower chamber will have a matter of weeks to coalesce behind a plan to keep the government funded. For the bulk of lawmakers, following two record breaking government shutdowns within the last 12 months, the appetite for another funding lapse appears low. And with the midterm elections quickly approaching, both sides of the aisle appear inclined to push off the fight for now.
