By Raphael Satter July 3 (Reuters) - A former member of the European Parliament who served on a committee investigating abusive surveillance was himself hacked using an Israeli-made spy tool, a Canadian tech watchdog group said on Friday. Citizen Lab said in a report that the phone of Stelios Kouloglou, a Greek television journalist-turned-lawmaker, was hacked at least three times between October 2022 and March 2023 using Pegasus spyware, a tool distributed by the Israeli company NSO Group.
