Taiwan’s National Security Bureau went live on Sunday with a website inviting Chinese nationals to pass intelligence to Taipei, framing the channel as a secure outlet for what it describes as a growing pool of mainlanders fed up with the system. The pitch is unusually candid for a counterintelligence agency: the stated aim is to expand the bureau’s range of intelligence sources, and the bureau called on Chinese citizens at home or abroad to come forward and “make changes with courage.” For a service whose entire premise is discretion, advertising the sourcing operation in public is itself the message.
