QuaDream’s software called ‘Reign’ grants users full surveillance capabilities over another person’s phone, including the ability to record calls, read messages and take photos by exploiting a security flaw in Apple iPhones, the Canadian Citizen Lab writes in a new report. QuaDream Ltd. is a smaller competitor of Israel’s NSO Group, which illegally spied until only a few years ago on government officials, journalists, dissidents and others often paid by authoritarian regimes.
