Luca Casarini is most prominent person to come forward since WhatsApp said that 90 people, across two dozen countries, had probably been hacked

The Italian founder of the NGO Mediterranea Saving Humans, who has been a vocal critic of Italy’s alleged complicity in abuses suffered by migrants in Libya, has revealed WhatsApp informed him his mobile phone was targeted by military-grade spyware made by the Israel-based company Paragon Solutions.

Luca Casarini, an activist whose organisation is estimated to have saved 2,000 people crossing the Mediterranean to Italy, is the most high profile person to come forward since WhatsApp announced last week that 90 journalists and other members of civil society had probably had their phones compromised by a government client using Paragon’s spyware.
