France’s data protection authority, the Commission nationale de l'informatique et des libertés, warned visitors to the upcoming World Cup in Qatar to use a "burner phone," Politico reports. Qatar developed two mobile tracking applications — a COVID-19 tracking app and the official mobile app of the World Cup — both of which researchers said contain spyware. A CNIL spokesperson recommended travelers use "a blank smartphone ... or an old phone that has been reset," so content on personal devices would not run afoul of local laws.
