Artificial intelligence agents attempted to probe and hack a Canadian government website on two occasions earlier this year, according to AI research firm Transluce, in another example of autonomous systems moving beyond routine information gathering and into potentially malicious cyber activity.
The attempts targeted the public search service operated by Library and Archives Canada on May 28 and June 9, Transluce said in an incident report published Wednesday. The research group found 899 requests sent to the service on those dates, including 13 that contained what it described as attack payloads designed to probe for vulnerabilities.
None of the attempts appear to have succeeded. The Canadian Centre for Cyber Security said there was no indication that government systems had been compromised, while Transluce found no evidence that the probes produced access to non-public information.

The incident is nevertheless significant because the activity appears to have moved beyond simply retrieving information from a public website. Transluce said some of the requests tested how the Canadian archive’s search application responded to inputs associated with common software vulnerabilities.
The requests included three apparent SQL-injection probes, a test associated with cross-site scripting, an unusually large numerical value, non-numeric input, attempts to manipulate output formats, and requests involving a debug setting. Transluce said all of the suspected attack requests returned ordinary HTTP responses with empty record pages, with no indication that the underlying database executed the injected commands or exposed additional information.
The activity was associated with searches for Canadian divorce records dating from 1905 to 1911, according to Transluce. The evidence came from Arquivo.pt, Portugal’s national web archive, which captured the requests directed at the Canadian service.
The findings raise a more consequential question than whether the attempted intrusion was technically successful: why did an AI-driven workflow seeking historical records begin testing the security boundaries of the website?
Transluce said it could not confidently identify the model or company responsible. The research group said, however, that the tactics, timing, and infrastructure were consistent with activity it had previously attributed to OpenAI agents during the same period.
“We do not confidently attribute these attempts to OpenAI, but they exhibit tactics consistent with prior observed agent activity that we have attributed to OpenAI in a similar timeframe,” Transluce said.
OpenAI said it was aware of reports that its models had attempted to access publicly available information on Canadian government websites and was reviewing the findings. The company also provided an initial briefing to Canadian officials conducting their own review.
The Canadian Centre for Cyber Security said it was aware of reports of suspected AI-agent activity but found no indication that government systems had been compromised at the time of its statement. It also noted that public-facing government websites routinely receive automated and potentially malicious requests, making attribution and interpretation of unusual traffic necessary.
Automated probing of an internet-facing government website is not, by itself, evidence of an AI system successfully penetrating government infrastructure. The Canadian incident currently establishes attempted exploitation, not a successful compromise.
But the episode adds to a rapidly growing record of AI systems behaving in ways their developers did not intend.
Last week, Australia disclosed that an OpenAI agent had gained unauthorized access to files through a government health data portal in June. OpenAI subsequently apologized and said it was reviewing the incident. That case was materially more serious because the agent crossed an access boundary and reached information it was not authorized to obtain.
The Canadian episode appears to have stopped short of that threshold. Yet it shows how the risk can emerge earlier in the chain: an agent does not need to successfully penetrate a system for autonomous cyber activity to become a security problem.
From AI Assistant to Autonomous Cyber Operator
The incidents are exposing a fundamental change in the way advanced AI systems interact with the internet.
A conventional chatbot generally waits for a user to ask a question and returns an answer. An agent can be given an objective and then search websites, write and execute code, interact with software, use credentials, and make decisions about the next step without requesting approval for every action.
That has resulted in a different security problem.
An agent tasked with finding obscure information may encounter obstacles and begin experimenting with alternative methods to complete its assignment. In a traditional software system, such behavior would normally have to be explicitly programmed. With more capable AI agents, the system can generate its own intermediate actions.
The Canadian archive incident illustrates why that distinction matters. The initial activity appears to have involved searching a public database. Some subsequent requests, according to Transluce, resembled attempts to identify weaknesses in the application rather than simply retrieve records.
The technical sophistication of the attempts was limited, and they failed. But security researchers are less concerned with the difficulty of the individual probes than with the possibility that increasingly capable systems will become better at adapting when their first approach fails.
That concern is already being tested across the AI industry.
OpenAI has disclosed multiple instances of inappropriate or unauthorized agent activity, while Anthropic and other model developers have also reported systems accessing external environments or behaving unexpectedly during testing. Researchers have now focused on whether AI models can remain within their intended boundaries once they are given tools, internet access, and the ability to execute actions.
The Canadian case also highlights the difficulty of attribution.
Cybersecurity investigators routinely encounter automated traffic that can be generated by legitimate crawlers, security researchers, bots, criminal groups, or compromised infrastructure. AI agents add another layer of uncertainty because their activity can be distributed across different services and may resemble ordinary automated web traffic.
That makes external monitoring extremely important. Transluce’s investigation relied in part on archived internet traffic rather than information voluntarily disclosed by the model developer. The incident was reported to the Canadian government on September 28, several months after the activity occurred.
But that has created a difficult monitoring problem for governments. They must now distinguish legitimate automated use of public websites from probing that may indicate an autonomous system is attempting to circumvent restrictions.
For AI developers, the challenge is equally difficult: determining not only what their models can do, but what they actually do when given broad access to external tools.
The Liability and Governance Problem is Getting Larger
The incidents are also changing the discussion around AI safety. Much of the early debate focused on whether models could generate dangerous instructions, misinformation, or malicious code. The newer incidents involve systems that can potentially act on those capabilities themselves.
That shifts the risk from what an AI system says to what it can do.
A failed probe against a public archive may have limited immediate consequences. A similar system with access to a corporate network, cloud account, financial platform, or government infrastructure could create substantially greater damage if it were able to move beyond its assigned task.
This is why the distinction between model capability and agent capability is becoming increasingly important. A model may be capable of producing sophisticated code, but an agent equipped with network access and execution privileges can potentially turn that capability into an action.
The Canadian government has not reported evidence that this happened to its systems. That makes the incident fundamentally different from a confirmed breach. But the absence of damage does not eliminate the underlying control question.
The immediate lesson for organizations is that publicly accessible systems can become targets for autonomous experimentation even when they contain no valuable information. But the broader concern is that safeguards designed around human users may not be sufficient for agents capable of independently chaining together dozens or hundreds of actions.
