Bipartisan Senate Group Asks DHS to Release StingRay Documents

The Department of Homeland Security should release unclassified documents shedding new light on the threat of cellsite simulators, or StingRays, in Washington and around the U.S., said Sens. Ron Wyden, D-Ore.; Cory Gardner, R-Colo.; Rand Paul, R-Ky.; and Ed Markey, D-Mass., in a letter to DHS Wednesday (see 1804100015). “The American people have a legitimate interest in understanding the extent to which U.S. telephone networks are vulnerable to surveillance and are being actively exploited by hostile actors.” The group asked DHS to release a PowerPoint presentation containing “additional details about the use of rogue [international mobile subscriber identity] catchers in the U.S." The presentation for federal employees had been marked "for official use only." DHS didn’t comment.
