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.
