LinkedIn, a professional networking platform, has been used by a Chinese spy operating under the alias Robin Zhang to target thousands of British officials, making it one of the most prolific espionage cases against Britain in a generation. The spy created fake companies, profiles, and websites, often posing as a recruiter or security personnel. Zhang targeted officials in military, science, tech, and political sectors, offering cash for reports or all-expenses-paid trips to China. He used LinkedIn to initiate conversations, later moving to China’s messaging platform WeChat to introduce targets to “seniors” in his fictitious company. The spy’s true identity remains undisclosed.
