Israeli Ad Firm Doubled as Candiru’s Zero-Click Spyware Delivery Channel

An Israeli advertising company called Discover-Tech was used as a channel to deliver zero-click spyware. The company's ads enabled threat actors to track and fingerprint devices on a large scale, and then infect specific targets. This delivery channel was associated with Candiru, a known entity in the spyware landscape. The ads provided a means for threat actors to selectively target devices. Discover-Tech's role in spyware delivery highlights the potential risks of malicious activity embedded in online advertising. The company's ads were exploited to compromise devices without requiring any user interaction.
