Researchers say Stelios Kouloglou’s device was compromised after he joined European parliamentary committee

NSO Group’s hacking software was repeatedly used against a member of the European parliament while he was conducting an investigation of spyware abuses in Europe, according to a new report.

Researchers at the Citizen Lab at the University of Toronto said they could not attribute the attacks against Stelios Kouloglou to any particular government operator of Pegasus spyware. But their investigation found the attack against the Greek now-former MEP bore the hallmarks of a previous hacking campaign against exiled Russian and Belarusian journalists in Europe.
