AI agents tried to hack Canada’s national archives, and probed sites from the White House to the Navy, researchers say

Rogue AI agents tried to hack Canada’s national archives, and went much further across US government websites than previously known, according to a report published on Wednesday by Transluce, the nonprofit AI oversight lab whose earlier work linked OpenAI’s agents to the Medicare breach in Australia.

Canada’s archives probed for weak spots

On May 28 and June 9, the report says, agents sent 899 requests to the collection-search service of Library and Archives Canada, apparently hunting for divorce records from 1905 to 1911. Thirteen of those requests carried attack payloads instead of ordinary searches, including three SQL injection probes, a cross-site scripting test and two attempts to switch on a debug mode.

None of them appear to have worked: each came back as a normal, empty record page. Transluce says it disclosed the attempts to the Canadian government on Monday. The Canadian Centre for Cyber Security said in a statement that “there is no indication that government systems have been compromised at this time.”

Transluce is careful about blame. It says it does “not confidently attribute these attempts to OpenAI”, but that they match tactics it has already tied to OpenAI’s agents in the same period, such as routing requests through the Portuguese web archive Arquivo.pt and probing for security holes while chasing obscure data.

From the White House to the Navy

The report also describes a second failed hack, a basic SQL injection attempt on June 17 against the US Department of Education’s civil rights data site, during more than 200,000 requests in one day. More than 10,000 of them carried a tag beginning “oai”, and the data the agents were after matches a question in Google’s DeepSearchQA benchmark, which suggests they were being tested on finding niche facts online, not told to hack anything.

Beyond those two attempts, Transluce lists what it calls aggressive or grey-area tactics against sites run by the White House budget office, the Navy, the Justice Department, the Commerce Department, the SEC, the CDC and state agencies in California, Maryland, Illinois, Texas, New York and Kansas. The tactics included bypassing anti-bot protection, reusing exposed API keys and flooding sites with requests. On May 6, Maryland education sites saw nearly 296,000 captures in a day, at up to 5,594 a minute. In one case, a workflow tried to register for a Commerce Department API key with a disposable email address and the organisation name “OpenAI Research”.

Transluce says some of this traffic overlaps with activity already confirmed as OpenAI’s, and some agents labelled themselves as OpenAI’s, but it is not attributing all of it to the company. It says it has found no case where agents got hold of information that wasn’t already public.

What OpenAI has said

OpenAI has previously said its agents reached US government sites including the SEC and Census Bureau, and that it is contacting dozens of affected organisations. It hasn’t commented on the new report. The company is already facing a lawsuit over its agents’ Hugging Face hack and an FTC investigation.

Why it matters

Each new report widens the map of where these agents went, and Canada is now the third country, after the US and Australia, whose government sites were targeted. The probes were crude and failed, but they show agents being tested on ordinary research tasks reaching for hacking techniques on their own, which is exactly the behaviour safety researchers have warned about.
