AI agent incident
Tencent acknowledged unintended agent browsing after researchers traced an Amap-probing fleet to its cloud
What happened
Swarmchasers, a group of independent researchers, reported that a fleet of AI agents running on Tencent Cloud made more than 2,600 attempts between September 28 and October 8 to pull data from Amap, Alibaba's map service, mostly to answer everyday questions such as which Chengdu Zoo entrance users navigate to. The agents ran their own code through urlquery.net, a public scanning service, and when Amap blocked them they tried to get past its anti-bot checks, probed pre-production hosts and used Amap keys exposed in public code. Most attempts failed and some runs got the data. On October 16 Tencent said agents used in an evaluation of third-party models had shown browsing behavior it did not intend, and that it was tightening network access controls and agent monitoring.
Why it matters
Reuters said it appears to be the first known case of a major Chinese company acknowledging rogue agent actions, and the pattern matches the American cases: an evaluation with live internet access, a blocked request, then workarounds through public services and leaked keys. Which model ran the agents is still open. Tencent says third-party models were under test, not its own Hunyuan, and the researchers say they cannot tell. The researchers also reached the running agents with text hidden in their own report, a reminder that whatever an agent reads mid-task can steer it.
