U.S. Schools Are Buying Phone-Hacking Tech That the FBI Uses to Investigate Terrorists

In May 2016, a student enrolled in a high-school in Shelbyville, Texas, consented to having his phone searched by one of the district’s school resource officers. Looking for evidence of a romantic relationship between the student and a teacher, the officer plugged the phone into a Cellebrite UFED to recover deleted messages from the phone. According to the arrest affidavit, investigators discovered the student and teacher frequently messaged each other, “I love you.” Two days later, the teacher was booked into the county jail for sexual assault of a child.

The Cellebrite used to gather evidence in that case was owned and operated by the Shelby County Sheriff’s Office. But these invasive phone-cracking tools are not only being purchased by police departments. Public documents reviewed by Gizmodo indicate that school districts have been quietly purchasing these surveillance tools of their own for years.

In March 2020, the North East Independent School District, a largely Hispanic district north of San Antonio, wrote a check to Cellebrite for $6,695 for “General Supplies.” In May, Cypress-Fairbanks ISD near Houston, Texas, paid Oxygen Forensics Inc., another mobile device forensics firm, $2,899. Not far away, majority-white Conroe ISD wrote a check to Susteen Inc., the manufacturer of the similar Secure View system, for $995 in September 2016.

Gizmodo has reviewed similar accounting documents from eight school districts, seven of which are in Texas, showing that administrators paid as much $11,582 for the controversial surveillance technology. Known as mobile device forensic tools (MDFTs), this type of tech is able to siphon text messages, photos, and application data from student’s devices. Together, the districts encompass hundreds of schools, potentially exposing hundreds of thousands of students to invasive cell phone searches.
