Targeted surveillance is a serious threat facing human rights defenders globally. Though often carried out by states, this practice is enabled by digital surveillance tools provided by private companies. However, the lack of transparency about the operations of the surveillance industry poses a serious obstacle for victims of unlawful surveillance to seek accountability and the right to remedy. This briefing seeks to shed light on one specific company – NSO Group – and thereby help to overcome this barrier. This briefing is jointly written by Amnesty International, Privacy International and The Centre for Research on Multinational Corporations (SOMO).
