I n September, the Department of Homeland Security (D.H.S.) signed a two-million-dollar contract with Paragon, an Israeli firm whose spyware product Graphite focusses on breaching encrypted-messaging applications such as Telegram and Signal. Wired first reported that the technology was acquired by Immigration and Customs Enforcement (ICE) an agency within D.H.S. that will soon be involved in executing the Trump Administration's promises of mass deportations and crackdowns on border crossings. A source at Paragon told me that the deal followed a vetting process, during which the company was able to demonstrate that it had robust tools to prevent other countries that purchase its spyware from hacking Americans—but that wouldn't limit the U.S. government's ability to target its own citizens.
