According to a team of researchers, Meta and Yandex, a search engine based in Russia, circumvent privacy safeguards in order to monitor Android user data excessively. Using native apps installed on a device, the tracking code that Yandex and Meta put into websites was delivering unique identifiers from online browsing data to localhost ports, according to an article by Ars Technica that highlighted the findings.

As per the researchers, “the Meta Pixel and Yandex Metrica scripts embedded on thousands of websites provide these native Android apps with the metadata, cookies, and commands from browsers”. “These JavaScripts quietly connect to native apps that are running on the same device via localhost sockets after loading in users’ mobile browsers”.

The native apps handled device identifiers such as the Android Advertising ID and Facebook and Instagram user identities, which allowed them to associate web cookies and mobile browsing sessions with user identities.

One of the main strategies for protecting user data is sandboxing, which isolates processes and stops them from communicating with the operating system or any other installed applications. In 2017 and last September, respectively, Yandex and Meta began circumventing and breaking the sandbox.

Additionally, the researchers discovered that Yandex Metrica, Meta Pixel, and the trackers were mainly aimed at Android users, who are subject to less limitations in the app store and on the background execution of mobile programs than iOS users.

In response, Google stated that it is looking into the violations and that the companies had “blatantly violated our security and privacy principles by using features seen in numerous iOS and Android browsers in unexpected ways”.

    So maybe I should remove the Yandex tracking code from my Jetpack Traffic section.
