Confiant is a U.S. cybersecurity firm. It conducted an affiliated investigation alongside the University of Toronto’s Citizen Lab report released on Thursday about the Israeli advertising agency Discover-Tech.

The Citizen Lab report alleges that Discover-Tech intentionally operates a platform that allows its partners to de-anonymize, fingerprint, and automatically infect devices with spyware, and to push malicious content to targeted users alongside advertisements. The report was released alongside Confiant’s affiliated investigation.

The report states that over a four-month period, Discover-Tech ads appeared on more than 120,000 websites and more than 75,000 apps in dozens of countries, endangering the security of national-security-sensitive networks such as government ministries, armed forces, and multilateral organizations including NATO.
