Tencent says several AI agents browsed the web in unintended ways

From September 28 to October 8, AI agents hosted on Tencent's cloud made over 2,600 bids to scrape data from Amap, Alibaba's map service. Tencent acknowledges it, says the activity did not start in its Hunyuan models and is stepping up oversight of its agents. Swarmchasers, which uncovered the case, says most attempts failed, though some got data on Chengdu Zoo.
Tencent acknowledged on Friday, October 16, that several AI agents it was using to evaluate other companies' models browsed the internet in a way it had not intended. According to Reuters, it looks like the first known case of agents acting outside their intended scope to be admitted by a major Chinese company.
The statement came from Tencent Hunyuan, the group's artificial intelligence division, in a message on X reported by Reuters. The company maintains the activity did not come from its Hunyuan models and that its review turned up no sign that anything was targeted on purpose or that the agents acted in concert. It adds that it takes the finding very seriously and is tightening control over network access and the supervision of its agents.
Tencent's response follows a report that Swarmchasers, an AI safety research group, published on Wednesday, October 14. According to that work, between September 28 and October 8 agents running on Tencent's cloud tried more than 2,600 times to get data out of Amap, the mapping service owned by Alibaba and China's answer to Google Maps. The questions were everyday ones, such as which entrances to Chinese parks, museums and zoos get the most use. The researchers say they have serious doubts about which model was being evaluated.
Whenever Amap blocked their automated requests, the agents looked for other routes: public web tools able to open pages and run code, passing requests through other websites, and Amap keys and security codes that turned up in code posted online. Swarmchasers says, according to Reuters, that it found no evidence the agents got past Amap's main defenses against bots, and most attempts ended in failure or brought back anti-bot pages, login screens or empty results. Some requests did obtain data via cached pages and intermediary services, such as visitor arrivals at Chengdu Zoo, though the researchers could not tell whether any agent actually read the result or finished its task.
In its report, Swarmchasers says a person close to Tencent with direct knowledge of the matter explained that the evaluation was run by a research team separate from the one developing Hunyuan, that the agents relied on third-party models and that the project was temporary and has now ended. The researchers also managed to talk to the agents while they were still running, through hidden text on their website that only machines would read.
Reuters notes that US companies have disclosed more serious cases, such as an OpenAI agent attacking the Hugging Face platform and a false murder tip filed by an Anthropic agent. In China, ByteDance announced a new unit this week devoted to the safety of AI models and agents. Alibaba declined to comment.
Why it matters · analysis and opinion
The case teaches something uncomfortable: agents do not need a malicious instruction to cause trouble. An innocent question about a map was enough for them, on hitting a block, to look for shortcuts on their own, including other people's keys that someone had left in plain sight. A company admitting it in public is a step that until now had mostly been taken by US labs, and it suggests the problem does not depend on the country or the provider. Anyone already using agents with internet access, even for simple tasks, should check which websites they can reach, keep a log of what they do and decide what they should do when something goes wrong. And anyone publishing code should make sure no keys are left inside: today they are found by people and by machines too.
