Syniverse provides backbone services to wireless carriers like AT&T, Verizon, T-Mobile, and several other carriers. It discovered the breach in May 2021 but it began in May of 2016.

Syniverse repeatedly declined to answer specific questions from Motherboard about the scale of the breach and what specific data was affected, but according to a person who works at a telephone carrier, whoever hacked Syniverse could have had access to metadata such as length and cost, caller and receiver’s numbers, the location of the parties in the call, as well as the content of SMS text messages.

The two presented at the Black Hat security conference in Las Vegas last week.
