Google’s Threat Intelligence Group has identified a sophisticated hacking toolkit named 'Coruna' that targets iPhones running iOS versions 13 to 17.2.1. According to NS3.AI, this toolkit can exploit devices without requiring any user interaction, posing significant security risks. It has been reportedly used by groups linked to Russia and China for espionage activities and cryptocurrency scams. Researchers have raised concerns that 'Coruna' may have originated from surveillance tools developed by the U.S. government, which are now being misused by cybercriminals. Users are strongly advised to update their iOS devices to protect against potential vulnerabilities.
