A MARTINEZ, HOST: A global media investigation that's been underway for months has found that spyware was used to track unsuspecting journalists, activists and politicians worldwide. The hacking software known as Pegasus is licensed by an Israeli firm and is typically used to track terrorists and criminals. The investigation by a consortium of 17 news organizations dug into a list of more than 50,000 cellphone numbers, given to them by Amnesty International and the journalism nonprofit Forbidden Stories. There were numbers belonging to heads of state, business executives and two women with close ties to the murdered Washington Post columnist Jamal Khashoggi.
