Researchers have uncovered a substantial spyware operation involving an Israeli ad-tech firm that utilized online advertisements to deliver zero-click spyware to millions of devices globally. Investigations by Citizen Lab revealed that targeted ads weaponized the online advertising system, enabling malware infections without user interaction. This unprecedented cyberattack particularly affected journalists and media organizations such as Al Jazeera. Reports indicate that the Israeli firm facilitated the deployment of spyware like Candiru through ads displayed on a vast network of websites. The alarming findings suggest that just viewing an online ad could potentially compromise device security, raising serious concerns about privacy and the integrity of digital advertising.
