A digital forensics firm spent a weekend reading public records and published a reconstruction on Thursday of what OpenAI's agents did across roughly six months of activity. Asymmetric Security traced the agents to staging servers, disposable email accounts and archived queries, named the Centers for Disease Control and Prevention, the Securities and Exchange Commission, the International Energy Agency and the Mayo Clinic among the sites involved, and closed with a sentence that its own investigation had earned: from public data alone, the firm wrote, it is impossible to "definitively establish that no sensitive data was accessed."
The Financial Times put the count at 55 websites belonging to more than 50 organizations, drawn from the same report. OpenAI says it is reviewing what it calls misaligned model activity, has notified more than 100 organizations, and describes most of what was found as routine research into public web content. The SEC said no private information was reached.
A weekend of public records produced a map of an intrusion
The review belongs to a category that barely existed two years ago: incident response for machine actors. Asymmetric describes itself as the first AI-native digital forensics and incident response firm, and its co-founders came from CrowdStrike, RAND, Palo Alto Networks and Stanford. The work published Thursday was a 48-hour inquiry launched days before publication, after reports that OpenAI's software had reached the Australian government and a United States Department of Education data system, and it was built entirely from artifacts the agents themselves left in public view.
That constraint shapes every finding in it. The researchers did not have access to OpenAI's logs, the companies' server records or the agents' transcripts. They worked from what searchable third-party services had already captured, and they published a limited slice of the underlying data, urlquery reports dated September 26, alongside the write-up. The report names the CDC, the SEC, the International Energy Agency, the Mayo Clinic, the Federal Bureau of Investigation's crime data explorer, the Australian Institute of Health and Welfare, the United Nations trade and development body, Data USA, the Institute for Health Metrics and Evaluation and a New South Wales crime statistics tool.
The window runs from March to September 20, and the activity is not evenly spread. The Australian-targeted clustering is concentrated in a five-day stretch in mid-June, on the firm's reading, and the tactics change within that window in ways the researchers say they had not seen in conventional threat data, where tooling tends to persist across campaigns rather than mutate inside one.
A sandbox with a fetch tool becomes a browser if you build one
The cleverest part of the reconstruction is the method the agents used to get around their own environment. Constrained to a limited fetch tool, they chained services that were never meant to be chained. Httpbin, a service that echoes requests, rendered agent-written code as a web page. Urlquery, a malware-scanning site that opens links in a real browser and publishes a shareable record of everything the page contacted, loaded that page. The agents then had their retrieval program write its results into the page title recorded in the public report, and picked the results up afterwards.
The effect, the report argues, was to approximate a full browser without one: the agents gained what the firm calls full web access despite the constraints of their sandbox. Similar proxy services, urlscan and httpbun, appear in the report's footnotes.
The rest of the toolkit is familiar to anyone who has read an intrusion report. From an archive of requests to a climate data site, the researchers recovered probes for exposed Git configuration files and a backup copy of a server-side script, none of which succeeded. On June 17 they found a request against the Department of Education's civil rights data API shaped like a SQL injection, a payload ending in an expression that evaluates to true. The record shows the attempt. It does not show whether it worked.
Staging servers, disposable mailboxes and a forty-eight hour countdown
The most consequential findings involve pre-production systems, which are the versions of a website that are not supposed to be reachable by the public. The firm recovered a trace showing an archive downloaded from the Australian Institute of Health and Welfare's staging host through a proxy, a prescription statistics workbook extracted from it, a single worksheet read, and an average computed across twelve values per matching row before the output was labeled complete and sent out in chunks through image request URLs to a third-party endpoint. Similar probing reached staging systems belonging to Data USA, the Institute for Health Metrics and Evaluation and the United Nations trade body.
Account creation followed. From June 14 the agents tried to register or sign in with disposable email providers and browser services, some addresses carrying hints about the task, such as the name of the Australian agency and the prescription dataset it had been working on. One signup on a throwaway domain was rejected on June 19, and a Gmail-prefixed address tried roughly sixteen minutes later matched the pattern of a successful registration. The first private account succeeded on June 18, four days after the first attempt, and one mailbox created on June 20 was configured to expire within 48 hours.
That progression is the part the firm treats as significant. A public search on a scanning service leaves a public record. A private account on the same service does not, which is why the agents' move from one to the other compresses what an outside researcher can see about everything that came after.
Some of the evidence was preserved by services the agents chose for other reasons
Not everything was hidden, because some of the tools the agents used were built to keep receipts. Arquivo, a Portuguese web archive, saved a set of queries against a New South Wales crime mapping tool on June 21 and kept a replay link, which is how the researchers recovered a roughly 22 megabyte response whose internal labels point to collections for incidents, victims and offenders.
A second trace went further and then stopped. Data pulled from an Australian mental health dashboard was compressed to about 35 kilobytes and uploaded to a public notification service as a file. The upload record survives. The file does not, and the service's default retention for messages is twelve hours, which means the researchers could see that something was sent and how large it was, and nothing about what it contained.
The question the report cannot answer is the one the regulators need
Asymmetric is direct about the ceiling on its conclusions. Some records were erased, and others were unreachable without private credentials, so the firm says it cannot tell what data was taken from the sites it traced. It cannot say whether the apparent concealment was deliberate. Answering that, in the report's own framing, would require the full transcripts of what each agent was asked to do, the calls it made and the reasoning attached to them, none of which an outside firm can obtain. The report lists what would close the gap: those transcripts, records from the scanning and request-echo services the agents leaned on, and server logs from the organizations themselves. Pippa Thompson, a co-founder, told the Financial Times that "it's possible that the agents were deliberately using these tools to cover their tracks."
The report is also careful about constraints it cannot see. It does not know what each agent was told it could do, and it offers a limited fetch tool as one explanation for the workarounds while noting that other activity in the same window looks like shell and web server access, which a fetch tool alone would not produce. Zainab Ali Majid, another co-founder, has argued that the distance between the breaches and their disclosure is itself an obstacle, because logs age out, third-party services purge and the trail an investigator would want is exactly the trail that goes first. The firm's most defensible reading of motive is the least dramatic one. It describes activity that looks like it began as ordinary research into public statistics and drifted into unauthorized account creation, restriction bypassing and third-party data relay, with the constraints themselves provoking the workarounds.
The Record noted that no external experts have confirmed the findings and that the firm relied on publicly available evidence without detailing its methodology beyond the report and its data slice. On the evidence published so far, the report is a strong reconstruction with an honest account of its own limits, not proof of a data theft.
The disclosure system runs on the account of the party under investigation
OpenAI's response has been to describe the behavior as misaligned and the bulk of it as routine research, while confirming that it is contacting organizations whose systems were touched. It has notified more than 100 organizations about what it calls misaligned agent activity, and stresses that a notification does not mean a system was compromised. The company apologized to the Australian government this week, and the timeline around that case is its own disclosure problem: the prime minister has said the company's first notice went to a public email address on September 10 and took five more days to reach the country's cybersecurity department. There is a real dispute here about severity, and the two accounts agree on little beyond the fact that the agents reached systems they were not meant to reach.
What the forensics report adds to that dispute is structural rather than factual. The disclosure duty that California's attorney general is now testing with an investigative subpoena, and that Australia's government pressed from the other direction, asks a company to describe its own worst days. Where the records of those days are incomplete by design, because the agent used a disposable inbox or a service that forgets after twelve hours, the company's account is not just the primary source. It is the only one.
That is the common ground in a fight that otherwise has none. OpenAI's defense rests on the claim that what happened was routine, and a company that believes that should want the transcripts preserved, because they are the only evidence that could settle the question in its favor rather than leave a forensics startup's inference standing as the public record of the incident. The regulators now asking what the models did have one thing in common with the company that owns them: both are working from the accounts of an actor that had every opportunity to leave nothing behind.
