A report released by Citizen Lab, a digital research unit based at the University of Toronto, has raised concerns regarding the role of an Israeli digital advertising agency, Discover-Tech, in the distribution of sophisticated spyware. According to the researchers, Discover-Tech’s advertising platform, known as Controlium, has been utilized to deliver 'zero-click' spyware—malicious software that can infect a device without any user interaction, such as clicking a link.

The investigation specifically highlights the compromise of dozens of mobile devices belonging to employees at the Qatari news organization Al Jazeera. Citizen Lab suggests that the spyware was delivered through digital advertisements served by Discover-Tech, which the firm describes as a specialized agency. The researchers argue that the infrastructure provided by the company allowed for the mass targeting of individuals through the digital advertising ecosystem.

While the report details the technical mechanism of the infection, it does not explicitly state whether Discover-Tech was aware of the malicious nature of the advertisements or if the platform was being exploited by third-party actors without the company's direct involvement. Discover-Tech has not yet provided a comprehensive public response to these specific allegations, and the report focuses primarily on the technical findings of the digital forensic investigation rather than the legal or corporate intent of the advertising firm.
