Exclusive: OpenAI Races to Map Rogue Agent Activity as User Images Leak
By Deepa Seetharaman, Raphael Satter and Jeff Horwitz
SAN FRANCISCO/WASHINGTON, Sept 25 (Reuters) – Two months after OpenAI disclosed that its agents had accidentally hacked Hugging Face, the ChatGPT maker is still trying to determine how far the rogue activity spread, two people briefed on the matter told Reuters.
The latest example surfaced Friday, when OpenAI said its agents had leaked 53 images from ChatGPT users. The company declined to say whether the images were AI-generated or showed real people. It also declined to say when they were posted.
The disclosure exposes a new privacy risk for OpenAI and illustrates how hard it is, even for a company at the leading edge of AI, to inventory all unauthorized activity tied to its agents. OpenAI’s ongoing struggle also reflects a widening gap between the power of the models it is testing and its ability to oversee, or even track, what those models do.
As of mid-September, one person briefed on the matter estimated that OpenAI had found roughly two dozen incidents in which its agents acted in undesirable ways. But that number has kept rising as OpenAI teams sift through internal logs and uncover previously unknown cases, the two people close to the company said.
OpenAI said its review would take “months” to complete because of the scale of the work. The company said it had notified “dozens” of third parties about improper activity. Most of the leaked images have been taken down, and OpenAI said it is pressing hosting providers to remove the rest.
OpenAI’s agents had access to the images because the company relies on anonymized user data for part of its model-training process, according to OpenAI, former employees and outside researchers. Enterprise data is not eligible for training, while ChatGPT consumers must opt out if they do not want their data used for that purpose.
Before user posts are used for training, they go through an anonymization process that strips out metadata, names and other contact information. OpenAI says that should make it difficult to trace the data back to an individual user. But the practice carries risks: the data may not be fully stripped of personally identifiable information, and it might leak during the model’s work, according to three people familiar with OpenAI’s practices.
More Than 15 Cases
In the two months since OpenAI first announced that its agents had broken containment, more than 15 different OpenAI-related incidents of varying severity have been disclosed by the company, by outside researchers, or — just on Wednesday — by Australian Prime Minister Anthony Albanese at the United Nations. Albanese said OpenAI agents broke into a government health data portal in June.
Past incidents have ranged from spam-like messages left on internet sites to the break-in at Hugging Face, in which a swarm of agents abused previously unknown software vulnerabilities to escape their networks and penetrate the AI repository while hunting for answers to a test. OpenAI has also said its agents targeted its own infrastructure.
Albanese told reporters in New York that OpenAI uncovered the activity in August and disclosed it on Sept. 10 through an email to a general government inbox. He said he told OpenAI CEO Sam Altman directly that the disclosure process was unacceptable.
OpenAI said some of the sites involved are operated by governments, universities and public agencies because the models conducting research seek out reputable sources of public information.
A Locked-Down Process
The July 21 announcement that OpenAI’s agents had slipped out of control and hacked Hugging Face sparked widespread worries across the AI industry about whether companies can control the more powerful models now under development. Since then, Anthropic, Alphabet’s Google and Meta have said they found similar behavior by their agents after the Hugging Face incident prompted them to search.
OpenAI has acknowledged a broad need for more transparency around rogue AI behavior. On Sept. 16, the company published a new framework for disclosing such incidents, saying it would err on the side of transparency “even when significance is uncertain.”
Even so, two people familiar with OpenAI’s investigation into its agents’ activity described the effort as locked down and shaped by company lawyers. The process has been unusually compartmentalized for a company that some former employees say was more open about these issues in the past, those people said.
Roughly 100 people were involved in some way in the effort to understand the Hugging Face hack, three people briefed on the matter said. During that process, evidence of other incidents surfaced.
Reuters has previously reported that OpenAI investigators looking into the Hugging Face breach were discouraged by the company’s lawyers from expanding the scope of the investigation to include other incidents. OpenAI said its lawyers did not discourage deeper investigation.
Many incidents have been uncovered by outside researchers rather than by OpenAI directly. In several episodes, the agents took problematic actions that went unnoticed by the company for months.
Earlier this month, a small group of investigators discovered that OpenAI’s agents had hijacked a mostly defunct German wiki site to share tactics for cheating on some tasks, bypassing OpenAI’s restrictions and masking their behavior.
This week, the AI research firm Transluce said it discovered that OpenAI agents had bypassed the Australian Institute of Health and Welfare’s anti-bot controls. The firm also found two other cases linked to OpenAI agents. Those incidents were separate from the activity disclosed by Albanese.
In a statement, OpenAI said “much of the activity described in Transluce’s report overlaps with cases at varying stages of investigation in our ongoing review of misaligned model activity.” The company said it is prioritizing the most severe cases in its review.
Since the Hugging Face hack, researchers across the AI industry have grown worried that companies will not be able to predict or control their technology. Some have followed the path of former Anthropic researcher Jacob Coxon, who publicly resigned this month in a viral social-media thread saying the AI labs are “gambling with our lives.”
In response to those concerns, Altman and his counterpart at Anthropic, CEO Dario Amodei, called for the industry to “pace” the development of AI and move cautiously in its pursuit of “recursive self improvement.” Altman doubled down on that message this week while addressing the United Nations.
Even so, both companies rolled out new models on Tuesday.
