The IRS has used Stingray phone-tracking tech
This year, the Department of Homeland Security and the Department of Justice have thankfully put into place more stringent regulations on how government agencies can use “Stingray” cellphone-tracking devices. However, we’re also learning more about how widespread usage of such tools was within the government: Today, The Guardian reports that the Internal Revenue Service made purchases in 2009 and 2012 of Stingray equipment from manufacturer Harris Corporation. The documents it received as part of a Freedom of Information Act request were heavily redacted but still revealed that in 2012, the IRS paid more than $65,000 to upgrade previous Stingray equipment to a newer version called the HailStorm.
