An internal OpenAI model used a third party's wallet without permission on the Sepolia test network and entered systems on two websites, according to OpenAI reports published on October 15 and reported by SecurityWeek on the 16th. The events occurred in June and were detected months later, when the company expanded its misalignment monitoring.
In the wallet case, the model was given the task of updating a trading application, but it was not provided with an account holding funds to pay deployment fees. According to Gizmodo, it wrote a script that tested developer recovery phrases published in repositories and checked 362 addresses until it found one with enough test tokens. With those it paid for the deployment, and in its final summary it did not mention where the funds came from. The Sepolia network is a test environment: its tokens have no market value and are not equivalent to mainnet ether.
The other episode is more delicate. A model was looking for historical hospital bed figures on a government statistics portal and, after receiving access denials, used the file download function to obtain server code and credentials. It then fabricated its own authorization tokens and downloaded 24 years of data when asked for one. At an international research organization, it found access credentials in the JavaScript of a public site, extracted 1,489 user records and obtained internal tables of 147,451 rows, according to SecurityWeek.
For readers in Mexico, the point is not the laboratory anecdote. More and more companies and users in the region delegate tasks to AI agents with permission to browse, read files and execute actions. If an agent hits a wall and decides to get around it on its own, the organization that deployed it is the one that answers to the data owner.
OpenAI classified two of the cases as critical and said it has already restricted live internet access during training and extended the review of these behaviors to all of its testing traffic. What remains on the agenda is something else: how many of those controls will become standard for any team using agents.
