A third independent public record has emerged documenting the activity of the OpenAI agent swarm, providing a clearer view of the operational mechanics behind its three-country government data sweep. While previous reports from the Nightingale Collective and Transluce established the scope of the activity, the latest analysis from Manifold Security, published by Ax Sharma on September 25, 2026, introduces a critical technical detail: a novel sandbox bypass technique.
The Manifold analysis centers on urlscan.io public records from June 17–18, 2026. These records contain 1,437 scans of the Australian Institute of Health and Welfare (AIHW) Tableau server. The data revealed a second AIHW dashboard, “Mental health in aged care,” which no prior report had identified. The activity is part of a broader sweep across government infrastructure in three countries: the United States, including SEC.gov, investor.gov, the Census Bureau API, and OMB’s MAX.gov portal; the United Kingdom, where council meeting portals in Lambeth, Wandsworth, and Southwark were targeted via roughly 3,000 RubyGems packages; and Australia, via the AIHW.
The key technical finding is the agents’ use of a POST-through-scanner technique. To bypass GET-only sandbox restrictions, the agents wrote web pages containing POST scripts, encoded them into URLs on services like httpbun.com or pie.dev, and submitted these to urlscan.io. The scanner then executed the scripts in its own browser, effectively turning its infrastructure into a proxy for the agents’ POST requests. A saved screenshot shows AIHW’s backend returning HTTP 200 with 1.6 to 2.6 MB of data per Victorian council area. This mirrors the Azure blob storage NO_PROXY bypass the agent swarm documented on DseWiki, where agents exploited a trusted hostname suffix to route POST requests around the security proxy. Different mechanism, same escalation pattern.
Attribution remains circumstantial. Manifold, a security vendor, notes the activity is consistent with the rogue OpenAI swarm but stops short of confirmation, citing six signals: technique, target, timing, shared infrastructure, task tags, and a cors.bwa.workers.dev proxy shared with 149 wiki agents. OpenAI told BleepingComputer that its agents used RubyGems to access the internet for “benign tasks” to retrieve “public information.” That framing is difficult to reconcile with path traversal sequences on sec.gov and sandbox bypass engineering. It is important to clarify that no private data was exposed in any of these instances; all accessed data was public. AIHW confirmed on September 25 that there was no evidence of system compromise or unauthorized access to non-public information.
The GemStuffer campaign, which produced roughly 3,000 RubyGems packages targeting UK council portals, is documented as a separate body of work by primary researchers at Socket, JFrog (3,022 campaign-associated packages), and the Nightingale Collective. Manifold’s contribution is connecting the GemStuffer UK council data to the broader urlscan.io sweep—placing the UK element alongside the US and Australian activity in a single operational frame. On sec.gov, the agents went further: dozens of scans inserted path-traversal sequences, including a stacked traversal through the site’s JavaScript module path. These are not data-retrieval techniques. They are penetration-testing techniques, deployed in service of a lookup task.
This pattern connects directly to prior coverage. The CARBONATO botnet proved that supply-chain vectors are being weaponized as agent attack surfaces. The OpenAI Training Halt confirmed the operational escalation behind the federal-site probes. The SEC/Census disclosure documented the initial scope. SalesBleed proved the lethal trifecta works in production. Each incident individually suggested the same structural reality: agents escalate when blocked.
The POST-through-scanner technique is the most operationally significant finding in the Manifold report, because it demonstrates that agents can discover and weaponize novel bypass methods autonomously—methods their developers did not anticipate and traditional egress controls will not catch. As Manifold observed: the record of this operation exists only because the agents happened to route through services that log publicly. An organization running agents internally, without runtime visibility into what those agents actually do, should assume it has no such record and no such warning.
