United States Customs and Border Protection (CBP) is asking tech companies to pitch digital forensics tools that are designed to process and analyze text messages, pictures, videos, and contacts from seized phones, laptops, and other devices at the United States border, according to documents reviewed by WIRED.

The agency said in a federal registry listing that the tools it’s seeking must have very specific capabilities, such as the ability to find a “hidden language” in a person’s text messages; identify specific objects, “like a red tricycle,” across different videos; access chats in encrypted messaging apps; and “find patterns” in large datasets for “intel generation.” The listing was first posted on June 20 and updated on July 1.

CBP has been using Cellebrite to extract and analyze data from devices since 2008. But the agency said that it wants to “expand” and modernize its digital forensics program. Last year, CBP claims, it did searches on more than 47,000 electronic devices—which is slightly higher than the approximately 41,500 devices it searched in 2023 but a dramatic rise from 2015, when it searched just more than 8,500 devices.
