Israeli Ad Firm Doubled as Candiru’s Zero-Click Spyware Delivery Channel
By Ionut Arghire
AI Summary
Israeli advertising firm Discover-Tech was used as a covert delivery channel for Candiru's zero-click spyware, enabling threat actors to fingerprint and track devices at scale through ad infrastructure before selectively infecting high-value targets. The technique bypasses traditional infection vectors by weaponizing legitimate ad-serving pipelines, making attribution and detection significantly harder. Security practitioners monitoring for Candiru-linked activity should add ad-network telemetry to their threat hunting scope.
