Amnesty International’s Security Lab, in collaboration with Amnesty’s European Regional Office, has uncovered a new case of misuse of a Cellebrite product to break into the phone of a youth activist in Serbia. The attack closely matches the form of attack that we previously documented in a report, ‘A Digital Prison’, published in December 2024. This new case provides further evidence that the authorities in Serbia have continued their campaign of surveillance of civil society in the aftermath of our report, despite widespread calls for reform, from both inside Serbia and beyond, as well as an investigation into the misuse of its product, announced by Cellebrite.
