Exposing a Global Surveillance Empire

In June, a sharp-suited Austrian executive from a global surveillance company told a prospective client that he could “go to prison” for organizing the deal they were discussing. But the conversation did not end there.

The executive, Guenther Rudolph, was seated at a booth at ISS World in Prague, a secretive trade fair for police and intelligence agencies and advanced surveillance technology companies. Rudolph went on to explain how his firm, First Wap, could provide sophisticated phone-tracking software capable of pinpointing any person in the world. The potential buyer? A private mining company, owned by an individual under sanction, who intended to use it to surveil environmental protesters. “I think we’re the only one who can deliver,” Rudolph said.

What Rudolph did not know: He was talking to an undercover journalist from Lighthouse Reports, an investigative newsroom based in the Netherlands.

The road to that conference room in Prague began with the discovery of a vast archive of data by reporter Gabriel Geiger. The archive contained more than a million tracking operations: efforts to grab real-time locations of thousands of people worldwide. What emerged is one of the most complete pictures to date of the modern surveillance industry.
