We analyzed Russian activist Andrey Pivovarov’s phone, finding that Russian authorities used forensic extraction tools made by Cellebrite to gain access to his device. A document prepared by Russian authorities confirms that Cellebrite was used to extract information to aid in Pivovarov’s prosecution. Importantly, we found that authorities continued to use Cellebrite for political repression even after the company had cancelled its contracts with Russian customers.

Following the widely-condemned arrest in July 2025 of prominent Kenyan opposition voice Boniface Mwangi, the Citizen Lab analyzed artefacts from devices seized during the arrest. We found that Cellebrite’s forensic extraction tools were used on his Samsung phone while it was in police custody. This case adds to the concerning pattern of the misuse of Cellebrite technology by government clients.
