Discover-Tech is an Israeli advertising agency named in a report by the University of Toronto’s Citizen Lab. The report alleges that the company’s platform enabled partners to identify and fingerprint devices and deliver spyware through targeted advertisements.

According to Citizen Lab, Discover-Tech ads appeared over a four-month period on more than 120,000 websites and 75,000 apps in dozens of countries. Researchers said they confirmed spyware infections on at least 45 Al Jazeera devices in 2024 and 2025, and linked the attacks with high confidence to spyware associated with Candiru, which the report said had rebranded as Integrity Labs.

Google said it blocked Discover-Tech from its ad platforms for systematically violating its policies. IAB Europe also suspended the company from its list of global vendors. Discover-Tech did not respond to CBC News’s request for comment.
