Security researchers at Citizen Lab and Confiant uncovered that an Israeli ad tech company, Discover-Tech, used its advertising platform to deliver zero-click spyware to targeted users simply by showing them an online ad. The company’s Controlium platform allowed spyware partners to profile and de-anonymize millions of individuals, fingerprint devices, and select specific users for infection using identifiers such as IP addresses, mobile ad IDs, or browser fingerprints. One partner named in the investigation is Candiru, an Israeli spyware vendor blacklisted by the US government; researchers found Discover-Tech-served ads delivered Candiru-linked spyware to at least 45 devices at a Qatar-based news organization across 2024 and 2025. This represents the first technical evidence that zero-click attacks - exploits requiring no user interaction - can be deployed through targeted advertising.
The investigators call on the advertising industry to tighten platform security, and some providers have already removed or suspended the firm from their services. Recommended mitigations for high-risk users include using ad blockers, disabling ad tracking, and regularly resetting mobile ad IDs. The findings demonstrate that ad delivery infrastructure can be repurposed as a precise, covert hacking pipeline, turning routine web ads into vectors for highly targeted, stealthy device compromise.
