The finding, published Thursday by the University of Toronto’s Citizen Lab, said the incident is likely to be the first confirmation of zero-click mercenary spyware delivered through targeted ads. The attacks, which worked on iOS and Android devices, are particularly pernicious because they work without requiring any interaction from the target and are invisible unless users run special forensic hardware or software. Citizen Lab said it confirmed that AdFection, as it named the campaign, infected 45 devices at international media organization Al Jazeera in 2024 and 2025.

The company acts as a broker between parties that want to display their ads and publishers or app makers that seek revenue in return for showing them.
