Meta Platforms halts Pixel script after researchers disclose potential tracking method impacting billions of Android users.
Researchers found that Meta and Yandex used native Android apps to listen on localhost ports, linking web browsing data to user identities without consent.
Native Android apps like Facebook, Instagram, and Yandex apps silently listened on fixed ports to de-anonymize users' browsing habits.
Meta confirmed pausing the script in question and is in discussions with Google, while Yandex denied tracking Android users' web browsing, stating compliance with data protection standards.
