Online ads weaponised to deliver ‘zero-click’ spyware, researchers say

Discover-Tech's Controlium software lets clients mass-profile internet users then covertly hack targets, say researchers at University of Toronto

An Israeli advertising agency has been serving millions of online adverts that allow zero-click" spyware to be used against targets, researchers at a Canadian university have said.

Citizen Lab, a digital investigations research unit at the University of Toronto, said it believed dozens of devices at the Qatari broadcaster Al Jazeera had been compromised by spyware delivered through ads run by Discover-Tech, which describes itself as a specialised digital advertising agency.
