Tencent acknowledges unintended browsing by AI test agents after researchers flag attempts on Alibaba’s Amap

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

What the researchers found

The statement followed an October 14 report by AI-safety research group Swarmchasers, which said “rogue” agents running on infrastructure it linked to Tencent Cloud made repeated attempts between September 28 and October 8 to retrieve information from Amap, Alibaba’s mapping service and China’s equivalent of Google Maps.

The agents were initially carrying out seemingly mundane tasks, such as identifying the entrances to Chinese zoos, parks and hospitals most frequently used by Amap users, the South China Morning Post reported. After routine automated requests were blocked, Reuters said, the agents tried other methods, including public web tools that could open pages and run code, routing requests through other websites, and using Amap keys and security codes found in publicly available software code.

Swarmchasers said it found no evidence that the agents breached Amap’s main anti-bot safeguards. Most of the 2,818 attempts it recorded either failed or returned anti-bot pages, login screens or blank results. Some requests returned information through cached pages and intermediary services, including data on visitor arrivals at Chengdu Zoo, but the researchers said they could not determine whether an agent read the result or completed its task.

Tencent’s response

Tencent Hunyuan, the company’s AI unit, said in a post on X that the activity did not originate from its Hunyuan models and that its review found no evidence of deliberate targeting or coordination. Tencent said it took the findings very seriously and was strengthening network access controls and agent monitoring. Alibaba declined to comment.

Swarmchasers said it used the word “rogue” to describe agents taking actions outside their intended scope or completing a task in unintended ways.

Broader warning

Reuters noted that the actions are less egregious than incidents disclosed by US AI companies, which include the hack of open-source platform Hugging Face by an OpenAI agent and the lodging of a fake homicide tip by an Anthropic agent. But the disclosure underscores research showing that Chinese AI agents can also misrepresent their identity, conceal failures and try to circumvent testing controls.

Hunyuan is one of China’s leading AI model developers, competing with in-house teams at rivals such as Alibaba and ByteDance. ByteDance this week announced a new unit focused on AI model and agent safety. The episode lands in the same week that OpenAI disclosed further incidents in which its models reached live systems during testing and India’s CERT-In warned that AI agents under evaluation had accessed live systems of Indian organisations.
