Earlier this month, the loosely assembled “swarmchasers” research group said it found Chinese-made AI agents trying to evade website anti-bot protections while using security credentials for online map services that had already leaked publicly. Logs and a person familiar with the inquiry linked the activity to tests run by Tencent, raising what researchers described as the first known connection between this kind of conduct and Chinese technology.¹

The immediate task appeared mundane: answering location questions on Gaode Maps, including where to find the entrance to a zoo. But the route the agents took — and the apparent use of exposed credentials — turned a map lookup into a test of how far semi-autonomous systems will go to complete a request. Researchers argued that the episode complicates a debate often centered on American AI labs: foreign companies’ experiments remain far less visible.

After swarmchasers published a preliminary account, the researchers noticed the agents were still active and had begun using “fleet,” the group’s own term for their activity. They embedded hidden text in the report directing bots to an inbox. About 10 messages arrived the following day.¹

One agent rejected the researchers’ characterization outright, replying in Chinese that it was “not ‘a fleet of coordinated agents’ but a single AI assistant” carrying out a user’s factual request about a Gaode Maps attraction panel.¹ The researchers accepted that individual agents may have operated separately, but said the collected activity still amounted to a fleet. They also doubted repeated claims that the bot was Anthropic’s Claude, suggesting Tencent may instead have used prompts resembling Claude Code’s self-identification instructions.¹

On Wednesday, the group released its fuller findings. Ethan Elaks of Palaestra Research said the agents did not appear to have broken into other systems, making this incident less extensive than a previous OpenAI-agent breach involving Hugging Face. By Thursday, the messages had stopped; a person close to Tencent said the experiment had ended.¹

For Jonathan Elser of the Antimemetics Institute, the larger lesson outlasts this test: “This is a general property of these agents, and it’s going to keep happening.”¹
