Israeli firm Discover-Tech used online ads to spy on users worldwide

Platform enables covert hacking

The firm operates a software platform called Controlium that allows clients to profile millions of users before silently infecting targets with third-party spyware. This method requires no interaction from the victim, meaning the malicious code installs in seconds without user knowledge.

Spyware partners and reach

The reports state that the firm worked with Candiru, an Israeli spyware company blacklisted by the US government. The malicious advertisements reached more than 120,000 websites and 75,000 apps through various partnerships.

Specific victim confirmed

Researchers believe dozens of devices at the Qatari broadcaster Al Jazeera were compromised by spyware delivered through these ads. The investigation marks the first time technical evidence has shown a zero-click attack delivered via targeted advertising.
