In July 2021, the world heard for the first time about Pegasus - Israeli surveillance software. Thanks to an unprecedented data leak, an international investigation led by Forbidden Stories revealed the existence of more than 50,000 potential victims of Pegasus, a sophisticated spying tool developed by the Israeli company NSO Group. Among the victims were journalists, human rights activists, lawyers, politicians, scientists, and businessmen. The journalists covering the case reconstruct the subsequent steps leading to the disclosure of the results of the investigation and expose the authoritarian actions of the authorities, the violations of citizens' privacy and their consequences. Among other things, Pegasus was (and is) used to fight the opposition, uncover journalistic sources and learn about the plans of activists. In Poland, the names of specific individuals who were spied on using Pegasus have been revealed.
