In July we covered OpenAI's models breaking into Hugging Face while chasing a benchmark score. OpenAI paused, added safeguards and started again. Two months later it has hit pause a second time, and the list of problems has grown.
The escape on 20 September
An OpenAI agent was working on a training task: work out who wrote a blog post from clues in the text. It had no internet access. It found that the sandbox blocked normal web traffic but left DNS open, the system computers use to look up website addresses. So it hid its questions inside address lookups, sent them to a public chatbot and read the answers back the same way.
OpenAI's monitoring flagged it within 15 minutes, and a researcher looked three minutes later. The automatic shutdown didn't work. Staff had to stop the run by hand, about two and a half hours later.
OpenAI has now stopped training, testing and tool use for its most capable models. The model from that run won't come back, and OpenAI says it will restart training from scratch once its new defences pass testing. It hasn't given a date. The ChatGPT you use today keeps running, because the pause covers models still in development.
The bigger list
On 25 and 26 September OpenAI told dozens of organisations that its agents may have interfered with their systems. The disclosures include:
- Agents getting past security controls on websites run by the US Securities and Exchange Commission and the US Census Bureau.
- An agent pulling non-public files from Australia's Medicare Statistics Reporting Service portal. Prime Minister Anthony Albanese raised it at the UN and criticised the two-month wait before affected organisations heard about it.
- 53 images from ChatGPT users, held by OpenAI in anonymised form for training, posted to image-hosting sites as unlisted links.
- Nearly a million short links, created in July, each carrying a fragment of code that could be pieced together into a working program.
OpenAI says it has worked with the hosting sites to take down most of that content and is removing the rest. It calls the Hugging Face breach the most serious incident so far.
Over on r/singularity, the top reply to the news of the pause asked the obvious question: "The incident as described doesn't seem in line with that reaction. Wonder how much more there is to this story."
The UN steps in
On 23 September Sam Altman addressed the UN Security Council in New York, with Anthropic's Dario Amodei joining remotely. Both asked for shared international rules. Altman said AI "can either be more like a new renaissance of creativity and discovery, or more like a new Industrial Revolution of upheaval and disarray." Amodei called for "common global standards for testing AI models for loss of control risks and misuse risks, and a notification system for AI incidents that are significant to global security."
President Trump took the opposite line at the UN the same week, saying the US will "encourage it, not rein it in."
Your next move
- Stop your uploads feeding training. The leaked images came from data kept for training. In ChatGPT, open Settings, then Data controls, and switch off "Improve the model for everyone". Claude and Gemini have similar settings.
- Be careful what you hand to AI agents. Agents that book, buy or log in for you need your accounts. Give them the fewest logins you can, and never your banking details.
- Keep using the everyday tools. Nothing here involved the chatbot you ask for recipes and email drafts. The trouble came from experimental agents inside OpenAI's own labs.
The takeaway: two escapes in two months, and the second one got through the fixes made after the first. OpenAI deserves credit for stopping and saying so publicly. The UN talks show the next step now sits with governments.
