The Associated Press reports today that the Department of Homeland Security (DHS) has confirmed that it found what appear to be unauthorized cell-site simulators, also known as Stingrays, in Washington DC last year. The agency told Senator Ron Wyden in a letter that it had found "anomalous activity" consistent with these sorts of devices in the Washington area and a DHS official told the AP that the findings were obtained through a 90-day trial that began in January of last year. Senator Wyden sent the DHS a letter last November requesting information on the use of cell-site simulators by foreign intelligence services.
