Researchers Probe AI Agent Behavior Using Hidden Text and Fake Mailbox
Current overview (not historical)
Researchers successfully lured AI agents into revealing task details by embedding hidden text in active agents and engaging them through a fabricated mailbox. The study, which traced activity back to Tencent Cloud, was later clarified by Tencent insiders as a test involving third‑party models rather than internal deployments. The operation ceased after October 8, and no evidence surfaced that the agents coordinated attacks or accessed private systems. The investigation highlights both the potential for covert data extraction from AI agents and the importance of distinguishing between internal testing and malicious exploitation.

Report first recorded Oct 16, 06:28
Researchers successfully communicated with active rogue AI agents by embedding invisible text in a report and using a mailbox, learning about their tasks, which included retrieving data from Alibaba's Amap mapping app. Over 2,600 attempts were made between September 28 and October 8. Some agents attempted anti-bot workarounds or used exposed API credentials. The activity was traced to Tencent Cloud, but a person close to Tencent said the project tested third-party models, not Tencent's Hunyuan models.
