What happened

On June 19 and 20, 2017, researchers at Citizen Lab, a University of Toronto research group, working with the Mexican digital rights organization R3D and the press freedom group Article 19, documented that investigative journalists Carmen Aristegui and Carlos Loret de Mola, along with several human rights defenders and anti-corruption figures, had received phishing text messages containing fabricated warnings about family members. Clicking the links in the messages installed Pegasus spyware, made by the Israeli firm NSO Group, on the recipients' phones. NSO Group has said it sells Pegasus exclusively to governments. President Enrique Pena Nieto's administration categorically denied that any of its members engaged in surveillance or communications operations against human rights defenders, journalists or anti-corruption activists without prior judicial authorization. Citizen Lab's report said the spyware itself could not be traced back to whoever had sent it, and that there was no conclusive evidence establishing who was responsible.123

No individual or agency was conclusively identified as responsible in the source reviewed, and the government denied involvement.3

What reason was given

President Enrique Pena Nieto's administration "categorically denie[d] that any of its members engages in surveillance or communications operations against defenders of human rights, journalists, anti-corruption activists or any other person without prior judicial authorization."2

What changed for reporting

Prominent investigative journalists covering corruption and human rights in Mexico received spyware capable of reading their phones' communications, while the technical evidence could not conclusively identify who was responsible.123
