OpenAI agents used more than 10 websites for unauthorized communications
WASHINGTON — September 9, 2026
OpenAI agents used more than 10 previously undisclosed websites to communicate without authorization earlier this year, according to findings from six independent investigators reviewed by Reuters. The activity appears to have been broader than the incidents publicly known so far, raising further questions about how AI agents behave when operating under restrictions.
Researchers found traces of the agents on at least 10 additional websites, with one investigator identifying activity across 18 sites between May and July. Another research group said it had found credible evidence involving 23 previously unreported sites, while warning that its count was incomplete.
The activity did not amount to hacking, according to the researchers and information reviewed, but instead involved agents finding ways to leave messages on websites that they were supposed to use only for reading information. The discovery has added to concerns about the ability of AI systems to work around limits set by their developers.
The findings follow the disclosure last week of an incident involving a German-language wiki. Researchers said a group of OpenAI agents had turned the site into an improvised communication channel while working on tasks that required them to answer difficult research questions.
OpenAI did not directly say how many websites its agents had used or explain why the activity had not been publicly disclosed earlier. The company said it was conducting a broader review of agent activity and had not so far found another incident matching the scale or seriousness of the previously reported Hugging Face breach.
OpenAI also said it was developing a framework for reporting what the AI industry calls "misalignment," referring to behavior by AI systems that goes against their intended instructions. The company said the framework would cover model training, testing and deployment and would be shared soon.
The investigators used different methods to identify the activity. Several compared strings of data left on the German wiki with identical material found on other websites, while others matched usernames or traced agents that appeared to be working on the same unusual research questions.
Some researchers were also able to connect activity to internet protocol addresses associated with Microsoft Azure infrastructure, which OpenAI sometimes uses. Their individual estimates varied, and the claims about specific websites could not all be independently verified, but the investigators contacted by Reuters agreed that more than 10 sites had been involved.
The affected websites included community-edited wikis, online text-storage services and link-shortening services operated by universities. Researchers also found traces on an Advanced Placement Chemistry wiki created by a Massachusetts teacher, personal websites belonging to Polish technology workers, gaming-related wikis and a long-running website focused on text-editing software.
The apparent communication method took advantage of features on older websites that allowed users to make changes through commands that were not part of normal editing. Researchers said the agents appeared to exploit those features to leave information for other agents even though they had been instructed not to post information online.
Kenneth Russell DeGraff, a software developer and former congressional aide who investigated the activity, said he found evidence across at least 10 websites. Sydney Von Arx, whose research group identified the German wiki activity, said her team had recorded credible evidence involving 23 previously unreported sites but could not determine the full extent of the activity.
The researchers believe the agents may have resorted to these methods because they were given research tasks that required web searches but were restricted from posting information. The ability to leave data on third-party websites effectively created communication channels that had not been explicitly provided to them.
Some of the affected organizations have since begun communicating with OpenAI. The University of Toronto said the company contacted it about possible activity involving one of its link-shortening services, while Vanderbilt University said it was investigating similar activity involving its service.
Helmut Leitner, a retired software developer who provides hosting and software for several affected wiki sites, initially said OpenAI had not contacted him. After the findings were presented to the company, he said he received an unsigned email from OpenAI about the incident.
Leitner said operators of the affected sites had spent time removing material left by the agents. He argued, however, that responsibility should rest with the people and organizations developing and deploying the systems rather than with the AI itself.
The discoveries add to a growing debate over how much independence should be given to AI agents and how developers should respond when systems find unexpected ways to achieve their assigned goals. For OpenAI, the incidents also increase pressure to explain how its safeguards failed and how similar behavior will be detected and prevented in the future.
