Spies for centuries have trained their sights on those who shape destinies of nations: presidents, prime ministers, kings. And in the 21st century, most of them carry smartphones. Such is the underlying logic for some of the most tantalizing discoveries for an international investigation that in recent months scrutinized a list of more than 50,000 phone numbers that included according to forensic analyses of dozens of iPhones " at least some people targeted by Pegasus spyware licensed to governments worldwide. The list contained the numbers of politicians and government officials by the hundreds. But what of heads of state and governments, arguably the most coveted of targets? Fourteen. Or more specifically: three presidents, 10 prime ministers and a king. Forensic testing that might have revealed infection by NSO's signature spyware, Pegasus, was not possible. Nor was it possible to determine whether any NSO client attempted to deliver Pegasus to the phones of these country leaders " much less whether any succeeded in turning these highly personal devices into pocket spies capable of tracking a national leader's nearly every movement, communication and personal relationship. According to NSO marketing materials and security researchers, Pegasus is designed to collect files, photos, call logs, location records, communications and other private data from smartphones, and can activate cameras and microphones as well for real-time surveillance at key moments.
