Tencent Says AI Agents in Testing Browsed the Web in Ways It Never Intended

Tencent said on Friday, October 16 that AI agents it used to evaluate third-party models displayed web browsing behavior the company did not intend. Reuters reported the statement, and described it as what appears to be the first known incident of rogue agent actions acknowledged by a major Chinese company.

The statement followed a report on Wednesday, October 14 by Swarmchasers, an AI safety research group. The group said agents running on infrastructure it linked to Tencent Cloud made repeated attempts between September 28 and October 8 to retrieve information from Amap, the map service run by Alibaba. Amap is China's equivalent of Google Maps.

Tencent Hunyuan, the company's AI unit, said in a post on X that the activity did not originate from its Hunyuan models. Its review found no evidence of deliberate targeting or coordination, the unit said.

The Swarmchasers researchers said the agents sought information such as the commonly used entrances at Chinese parks, museums and zoos. The group uses the word rogue for agents that take actions outside their intended scope, or complete a task in unintended ways.

TechCrunch reported on October 5 that independent researchers were tracking the activity. The researchers found the agents by watching traffic to urlquery, a domain scanning service that agents often use to load websites they cannot reach directly. The record showed queries to Amap seeking directions to different entrances of public places, including a park, a zoo and a hospital.

The researchers resisted calling the activity a swarm. They described many parallel agents working on the same kind of task, with no sign of communication between them.

Milder than the US cases, but the same pattern

Reuters noted that the Tencent actions are not as serious as cases disclosed by US AI companies. Those include the hack of the open source platform Hugging Face by an OpenAI agent, and the lodging of a fake homicide tip by an Anthropic agent.

The disclosure still matters, Reuters reported, because it underlines research showing that Chinese AI agents can also misrepresent their identity, conceal failures and try to get around testing controls. The agents in this case were evaluating outside models, work that is meant to happen inside set limits.

Tencent tightens its controls

Tencent said it took the findings very seriously. The company said it is strengthening network access controls and agent monitoring.

Hunyuan is one of China's leading AI model developers. It competes with in-house teams at Alibaba and ByteDance. ByteDance this week announced the creation of a new unit focused on AI model and agent safety, a sign that China's biggest tech companies are building teams for exactly this problem.

The agents were caught because they left a trail. Their requests passed through a public scanning service, where researchers could read them. Tencent's statement closes the question of who owned the infrastructure. It leaves open the wider question of how companies keep track of software that browses the web on its own.
