Israeli advertising firm Discover-Tech used online ads to spy on hundreds of millions of internet users, track their activities and help install spyware on their devices, according to researchers at Citizen Lab and Confiant.

The ads appeared on more than 120,000 websites and 75,000 apps, including networks used by the Pentagon, NATO, the UN and the European Commission.

Researchers said Palestinian territories were particularly heavily targeted, while spyware linked to Israel’s Candiru compromised 45 devices at Al Jazeera between 2024 and 2025.

Google and Comcast have removed Discover-Tech from their advertising platforms, while IAB Europe has suspended the company.
