Russian Authorities Used Cellebrite UFED to Break Into Human Rights Activist’s iPhone

**Executive Summary:** Forensic analysis and an official Russian forensic report indicate authorities used Cellebrite UFED (UFED 4PC and UFED Physical Analyzer) to perform a full-device extraction of Andrey Pivovarov’s iPhone in June 2021, leaving MobileLockdown artifacts and a specific Host ID; extracted messaging data were searched for political contacts and may have enabled subsequent phishing targeting attributed to the COLDRIVER group, highlighting misuse of commercial forensic tools for political repression and enforcement gaps around vendor restrictions.
