The U.S. Postal Inspection Service (USPIS) owns sophisticated hacking tools that can breach iPhones, and has used them hundreds of times over the last several years, according to USPIS records.
Law enforcement’s use of hacking tools such as Cellebrite and GrayKey has attracted considerable attention in recent years, particularly following reports that the FBI used the Israeli-based Cellebrite to help access the iPhone belonging to San Bernardino shooter Syed Rizwan Farook—though there has since been reporting to the contrary. More recently, records obtained by Vice Motherboard last year revealed how police departments use GrayKey.
