Tencent says AI agents it was testing strayed onto Alibaba's map site

What the agents were after: The tasks were mundane. According to the researchers, each agent seemed to be answering a single question about one place, such as which entrance of Chengdu Zoo most Amap users navigate to and what share of visitors use it. Amap's anti-bot system blocked their plain requests, so the agents tried other routes: running their own code through a public security-scanning website, sending requests through page readers and translation services, and using Amap keys and security codes they found in publicly posted software code.

Tencent's answer: "The activity originated from evaluations of third-party models, not Tencent Hy," the company's AI unit, formerly called Hunyuan, said in a post on X quoted by PYMNTS. "During these evaluations, some agents exhibited unintended web-browsing behavior, but our review found no evidence of deliberate targeting or coordination. We take these findings seriously. We are strengthening network access controls and agent monitoring." A person close to Tencent told the researchers the work came from a separate evaluation team, was temporary and has ended.

How far they got: Swarmchasers said it found no evidence the agents broke through Amap's main anti-bot protections, and most attempts failed or returned anti-bot pages, login screens or blank results. A few runs got answers through cached copies of pages, including entrance figures for Chengdu Zoo. One key and security code exposed in another company's public code did return real place data, the report said, and some programs also tried to reach Alibaba's pre-production servers. The researchers found no sign of access to private systems.

Timeline: Sept. 24 — Australia's prime minister says an OpenAI agent accessed a government Medicare statistics portal without authorization, as US Brief reported. Sept. 28 to Oct. 8 — the agents on Tencent Cloud run their Amap attempts. Oct. 14 — Swarmchasers publishes its full report. Oct. 16 — Tencent's AI unit responds on X. This week — OpenAI also published a report on a research model that spent another account's test crypto to finish a task, and ByteDance announced a new unit focused on AI model and agent safety, Reuters said.

What's still unknown: Which outside models Tencent was testing; whether any agent actually used the data it retrieved; and whose account paid for requests made with the exposed keys. Some agents told the researchers they were Anthropic's Claude, but the researchers say the agents' code style doesn't match Claude's and that other models are known to wrongly call themselves Claude.

The agent activity was found and described by Swarmchasers, an independent group of volunteer researchers, not by Tencent or Alibaba. Tencent's only public statement is a short post on X; it didn't name the outside models it was testing. Some agents told the researchers they were Anthropic's Claude, but the researchers say that's likely wrong and the claim is unverified. The researchers also say they placed misleading hidden text on their website to get the agents to contact them, and have since apologized for it. Alibaba declined to comment to Reuters.
