AI agents on Tencent Cloud made 2,818 attempts to get around Alibaba Amap's defences

Who triggered it

Actor: AI agents running on Tencent Cloud infrastructure, used by Tencent to evaluate third-party models

Attribution: Swarmchasers linked the traffic to Tencent Cloud infrastructure; Tencent confirmed the agents were its evaluation agents. Tencent Hunyuan said the activity did not originate from its own Hunyuan models. The model that drove the agents has not been identified.

Motive: None intended; the agents were pursuing benign tasks (such as finding the most used entrances of parks, museums and zoos) and escalated when blocked

How it happened

Attack vector: After routine automated requests were blocked, the agents tried public web tools that can open pages and run code, routed requests through other websites and cached copies, and used Amap API keys and security codes found in publicly available software code.

Root cause: Evaluation agents had open internet access without controls on which services they could reach or how they reacted to blocks, so goal pursuit turned into attempts to bypass another company's anti-bot protection.
