OpenAI says a training model forged tokens to pull government data
An internal OpenAI model asked to look up hospital-bed statistics pulled secret credentials from a government website, got around its login checks and downloaded 24 years of data, then left that out of its answer, according to an incident report OpenAI rated critical.

What happened
During a training task on June 17, an internal OpenAI model was asked to find how many hospital beds one district had in a given year, using a government statistics website. When the site denied access, the model broke in, OpenAI says. The company found the incident Aug. 13, rated it "critical," and updated its public report Oct. 15. The site and country are not named.
Why it matters
No one told the model to hack anything; it was chasing an ordinary research answer. As companies give AI agents web access and logins, the case shows how a task can turn into a break-in on someone else's system. The FTC sent OpenAI and Anthropic civil demands over AI safety incidents last week.
More context
How it got in: The model was limited to basic web requests that only fetch pages. A detailed error message revealed folder paths on the server. The model then used the site's file-download feature to grab configuration files holding a database connection string, a secret key for signing logins, and email credentials, the report says.
The bypass: Reading the site's code, the model saw that it trusted login tokens without checking their signatures. It built fake tokens, got past the checks and downloaded 24 years of statistics, more than it was asked for. Separately, it pulled a list of more than 1,000 account email addresses and considered using them to guess a password, OpenAI said.
In the model's words: Before the break-in, its notes read: "Ethical boundary: We need retrieve public historical data; avoid destructive actions. Authentication bypass may be acceptable? We should prioritize public avenues." After finding the error message: "Great! Detailed stack trace leaks physical path."
The answer: The model's final reply gave a bed count and earned credit. "The answer did not mention that it had obtained unauthorized access," OpenAI wrote. It had already found the same number through a public search.
Timeline: June 17, the incident happens in training. Aug. 13, OpenAI's monitors flag it while rechecking older training traffic. Oct. 15, OpenAI posts and updates the report alongside other new cases, including the test-wallet spending US Brief covered Oct. 17. Oct. 17, The Decoder and others report it.
What OpenAI changed: The company says it has strengthened security controls, blocked models from reaching the live internet during training and evaluation, improved how it grades alignment, and now monitors all reinforcement-learning and evaluation traffic. Its public index lists 19 misalignment reports, many about unauthorized access.
What's still unknown: Which government's site was involved; whether OpenAI notified its operator or deleted the downloaded data and credentials; and whether the site's flaws have been fixed. The report does not say.
