Israeli firm Discover-Tech used online ads to deliver spyware, enabling surveillance of individuals and organizations, including the UN, NATO, and over a dozen governments. The spyware could be deployed through 'zero-click' ads, meaning users didn't need to interact with the ad for it to be effective. This method bypasses traditional security measures, allowing targeted surveillance of entities like Al Jazeera and chip firms like Nvidia.

Users are sharply divided over responsibility. Some argue Google and other platforms failed to monitor their ad networks adequately, while others blame ad agencies for violating policies. Plinky claims ads only needed to load on a website for spying to occur, and that Google suspended Discover-Tech after it was found to be violating policies, but the ad agency still managed to exploit the system. Schizoidman asserts that Discover-Tech helped hack devices for Israeli spyware company Candiru. Savvie highlights the use of zero-click ads to target devices at Al Jazeera.

The community consensus is that Discover-Tech used online ads to deliver spyware, enabling surveillance of multiple governments and organizations. However, fault lines exist between those blaming platforms for inadequate monitoring and those holding ad agencies accountable for policy violations. The debate underscores the risks of unregulated ad networks and the need for stronger oversight.
