Terrorists behind Paris attacks used burner phones and not encryption to avoid being tracked. Police have found several unused burner phones still in their wrappers in a place used by the group of terrorists. The New York Times cites a 55-page report compiled by the French antiterrorism police for Frances Interior Ministry and explains how the terrorists have used phones activated less than an hour before the attacks. Police also found a Samsung smartphone in a dustbin with a Belgian SIM card used exclusively for the operation.”]
