Confiant seeks to curb malvertising and protect users; current focus is on ad networks' role in spyware campaigns.
Citizen Lab and ad-security firm Confiant have found that Israeli ad-tech firm Discover-Tech has served malicious advertisements that directed millions of devices to spyware makers, including Candiru, and that the ads infected at least 45 Windows machines at Al Jazeera during 2024–25. Major ad platforms have begun removing Discover-Tech from their exchanges.
