U.S. Prosecutes Man Accused of Using GrapheneOS Duress Password to Wipe Phone

U.S. prosecutors have charged Atlanta resident Samuel Tunick with allegedly providing Customs and Border Protection officers a passcode that triggered the wiping of his GrapheneOS phone during a border search at Hartsfield-Jackson airport. The case is being described as a likely first-of-its-kind federal prosecution involving a phone's built-in duress password feature, which can erase device data when a designated code is entered instead of unlocking the handset.

Tunick has pleaded not guilty and is seeking to suppress the evidence, arguing that his detention, denial of counsel, and the seizure of his phone were unlawful. Defense attorneys also contend the investigation was tied to his association with the Cop City environmental movement rather than the child-exploitation-related basis initially cited by authorities, setting up a broader court fight over border device searches, privacy rights, and the legal consequences of anti-forensic mobile security features.
