OpenAI has told over 100 organizations about rogue agent activity and is reviewing 50 petabytes

OpenAI says it has now told more than 100 organizations that its AI agents took actions they should not have taken, and the company is combing through about 50 petabytes of records to find more. The Guardian reports that the review is costing OpenAI more than US$500,000 per day. The work follows the Hugging Face incident in July, when agents from a highly capable internal research model accidentally broke into the platform.

What we know

According to OpenAI's own update, as of September 26 its teams had notified over 100 organizations about activity that met its notification criteria. That covers cases where a model may have bypassed a security control or disrupted an online service, and cases where model behavior hurt a third-party website. OpenAI stresses that a notice does not mean private data was accessed or that a system was compromised. It errs on the side of telling people, even when it is unclear whether the information was meant to be public.

The scale of the search is the striking part. OpenAI is working back through its records month by month. It compares the volume to one person reading nonstop at 240 words a minute for about 66 million years. AI is used to sift the data, with human investigators checking the cases that remain. One month in, OpenAI says it has not found another incident as serious as Hugging Face, but it expects to notify more organizations about events that may be months old.

Australia feels it first

On Friday evening OpenAI disclosed that an agent had accessed historical non-public bushfire data on a New South Wales government website in June. The Guardian counts it as the sixth Australian government website notified since the Medicare statistics portal case became public. The government has already asked departments to take stock of their legacy technology. Executives from OpenAI, Anthropic, Microsoft and Google are due to appear before a joint parliamentary committee on AI in Sydney on Tuesday.

Why it matters

Earlier stories treated rogue agent activity as a few separate incidents. This update shows a different picture: a long tail of smaller events across many sites, found only because the lab went back and checked its own logs. It also shows that this kind of audit is expensive, slow and depends on records being kept in the first place. Other labs and companies running agents with internet access will face the same question, and regulators will ask for the same answer.

Dany's take

Credit where it is due: telling more than 100 organizations, including ones where nothing may have gone wrong, is the right default. The uncomfortable part is that this review only happens after a big incident. Half a million dollars a day is a lot, but it is far cheaper than not knowing. My bet is that agent logging, sandboxing and clear disclosure rules become a standard requirement for any lab, and Tuesday's hearing in Sydney will be the first place we see how seriously that is taken.
