Bad Version of Vulna Active on Google Play – in GTA V PC Countdown

GTA V PC Countdown, a rather popular application on Google Play, incorporates a vulnerable version of ad-serving framework AppLovin, also known as Vulna. It’s extremely aggressive at collecting private information via applications that register hundreds of millions of installs.

It gathered over 50,000 installs despite its requesting a great many details highly invasive for users’ privacy.

The application, comprising two ad-frameworks, AppLovin and Airpush SDKs, can access information including GPS- and network-based location, network and Wi-Fi connections access, phone status and identity. Plus, it also includes permissions to read the accounts on the device, Web bookmarks and history, protected storage and modify and delete the contents of USB storage.

By installing such an application and granting the above-mentioned permissions, users expose themselves and their sensitive data to unauthorized scrutiny.

Too few of these permissions can be justified by the profile of this application, which is a rudimentary counter in the form of a wallpaper or widget to call attention to a GTA V PC release allegedly scheduled for March 2014.
