🚨Discover-Tech's Controlium Hacks Millions with Zero-Click Spyware

Your ads could be secretly hacking you

TL;DR

Researchers reveal how millions of users have been served ads that secretly profile and hack them with zero-click spyware. The Controlium platform, used by Discover-Tech since 2024, targets government officials, journalists, and more.

Researchers at the University of Toronto have uncovered a disturbing truth: millions of internet users have been served ads by Discover-Tech that secretly profile and hack them with zero-click spyware. The Controlium software, which has been in use since 2024, allows clients to mass-profile internet users and covertly install third-party spyware on their devices. This means that a user's identity and IP address can be harvested when they view a seemingly benign ad, and if selected as a target, a malicious code containing spyware is sent to their device. The software has been used to target government officials, journalists, businesspeople, activists, academics, and embassy workers in Yemen, Brazil, Mexico, Czechia, and more. This is a major security threat for states, the private sector, civil society, and everyone else.
