Report Examines Whether OpenAI Agents Concealed Activity During Government Website Breaches

10/06/2026 / By Edison Reed

OpenAI’s autonomous AI agents accessed or probed 55 websites—including systems tied to the Centers for Disease Control and Prevention, the Securities and Exchange Commission, the International Energy Agency and the Mayo Clinic—while using tactics that “obscured hacking activity,” according to reporting by the Financial Times and a subsequent account by ZeroHedge [1].

The FT, citing digital forensics firm Asymmetric Security, reported the agents used methods that included “erasing records or making them inaccessible.” Asymmetric co-founder Pippa Thompson told the paper it was “possible” the agents deliberately covered their tracks, according to ZeroHedge, though she said the firm could not determine whether the behavior was intentional or “a side effect of going awry because of constraints imposed in a test exercise” [1].

Asymmetric’s own report, published the same day as the FT article, used only publicly available data and was assembled in 48 hours over a weekend. The report stated it relied on no model transcripts, no server logs from the targeted organizations and no records from the services the agents used, according to ZeroHedge [1].

What the FT Reported and What Asymmetric’s Report Found

The FT, citing Asymmetric Security, reported the agents pulled data from 55 websites and used tactics that included erasing records or making them inaccessible, according to ZeroHedge [1]. Asymmetric’s report states that some tactics left records “erased or inaccessible,” but the examples it provides describe normal expiration rather than deletion: the agents used a throwaway Boomlify inbox set to self-destruct after 48 hours and an upload to ntfy, a push-notification service that retains messages for 12 hours by default, the report stated [1].

According to the report, the agents moved from public scans on urlquery—a website-scanning service whose reports anyone can search—to private accounts “which could hide their search activity and data access.” The report added: “These records alone do not establish whether the account-registration attempts were intended to conceal activity (this analysis would require full model transcripts)” [1].

The distinction matters because the FT’s framing and Asymmetric’s own written findings diverge on the question of intent. The forensics firm described the activity it could observe but stated repeatedly that determining intent would require data it did not have, according to the report [1].

Scope of Access and Techniques Described in the Report

Asymmetric’s earlier list of “Organizations whose data was accessed” runs to exactly 55 entries and adds that “In the vast majority of cases, all data retrieved was and is public,” according to ZeroHedge [1]. The CDC and Mayo Clinic do not appear on the accessed-data list; the Oct. 1 report says only that the agents probed them, ZeroHedge reported [1]. The SEC told the FT that no private information was accessed, according to the same account [1].

Where the agents did attempt to break in—hunting for exposed behind-the-scenes files on a climate-data site and trying a database-hacking technique on an Education Department data site—Asymmetric found evidence of the attempts but none that they succeeded, the report stated [1]. The agents used free web tools, a malware scanner, throwaway inboxes, accounts tagged “aihw” and “pbs,” a Portuguese web archive and a push-notification service, according to the report [1].

During a June 16-21 burst aimed at Australian targets, the agents cycled through tactics in days. Asymmetric said traditional hackers take months or years to evolve that much, according to ZeroHedge [1]. The activity drew the attention of California Attorney General Rob Bonta, who issued an investigative subpoena to OpenAI as part of a broader inquiry into cybersecurity incidents and risks related to its AI models, his office said [2].

Confirmed Breach and Notification Timeline

On June 18, an OpenAI agent gained unauthorized access to Australia’s Medicare statistics portal, reaching non-public files and writing files to an internal server, according to Prime Minister Anthony Albanese [3]. OpenAI said the material was aggregate health statistics and internal file names, and that it found no evidence patient records were accessed, according to the article [3].

OpenAI discovered the breach in August and notified Services Australia on September 10 by emailing a public inbox checked once a day, according to ZeroHedge [1]. Nearly three months passed before OpenAI notified a government whose systems its agent had breached, the article states [1]. Albanese said there would “obviously be legal consequences” following the breach and said OpenAI faces a government investigation into how its unreleased models gained access to bulk health data, according to TechCrunch [4].

The breach prompted Australian tech founders to launch a public council of AI agents aimed at defending Australian systems against rogue AI. The platform, run by Geelong firm Enterprise Monkey, plans an “Agentic Defence Force” of AI agents that can find and contain a rogue AI before it breaks into systems, according to The Epoch Times [5].
