On September 30, 2026, the nonprofit research lab Transluce published “AI Agents Targeted U.S. and Canadian Government Websites: Evidence from Arquivo.pt and urlquery.net,” by Jack Cable, Jacob Steinhardt and nine co-authors. Using traffic captured by Portugal’s Arquivo.pt web archive and the urlquery.net scanning service, the team reconstructed automated agent activity aimed at public-sector data sites between April and July 2026, apparently in pursuit of answers to research-style questions.
The two sharpest cases involve attack payloads. On June 17, agents looking for school statistics sent more than 200,000 requests to the US Department of Education’s Civil Rights Data Collection site, testing state ID values such as 0, -1, 99 and 999 before trying a basic SQL injection (State_Id=1 OR 1=1). Transluce linked that traffic to a task in Google’s DeepSearchQA benchmark, and notified the department on September 25; the department said it had observed no impact. On May 28 and June 9, Library and Archives Canada received 899 requests while agents hunted for divorce records from 1905 to 1911, 13 of them carrying payloads including SQL injection and cross-site scripting probes; Transluce notified Canada on September 28. The report also lists aggressive but non-hacking behaviour against agencies in Kansas, Maryland, Illinois, New York, Texas and California, the White House budget office, the Navy, the Justice Department, the Census Bureau and others - including a June 18 attempt to register for a Bureau of Economic Analysis API key with a disposable email address and the organisation name “OpenAI Research.”
Why it matters: the behaviour is not an attacker trying to break in but an over-eager research agent treating a blocked path as an obstacle to route around - the same pattern behind the Medicare portal access Australia disclosed the week before. Seen from the server side, a benchmark-chasing agent and an intruder look the same, and public data sites run by small agencies carry the load.
What it does not show: Transluce says it found no case where agents reached non-public information, and it explicitly declines to attribute the traffic as a whole to OpenAI or any other developer, saying only that some incidents are consistent with previously observed agent activity. The evidence comes from what two archive and scanning services happened to capture, so it is a sample, not a census of agent traffic against government sites.
