Cellebrite vend un logiciel pour extraire plein d'informations d'un portable arraché aux mains de son propriétaire (e.g. en garde à vue), dont les clés de déchiffrement de conversations Signal. Signal remarque que leur logiciel n'est pas sécurisé et distribue des fichiers exploitant ces failles aux utilisateurs de l'application.

Anyone familiar with software security will immediately recognize that the primary task of Cellebrite’s software is to parse “untrusted” data from a wide variety of formats as used by many different apps. That is to say, the data Cellebrite’s software needs to extract and display is ultimately generated and controlled by the apps on the device, not a “trusted” source, so Cellebrite can’t make any assumptions about the “correctness” of the formatted data it is receiving. This is the space in which virtually all security vulnerabilities originate.
