Researcher’s from paloaltonetworks  said, “132 Android apps on Google Play infected with tiny hidden IFrames that link to malicious domains in their local HTML pages

The most popular one having more than 10,000 installs alone .most likely that the app developers’ development platforms were infected with malware that searches for HTML pages and injects malicious content at the end of the HTML pages it finds ,Researcher’s said.

Infection Working Function

Palo Alto Networks’ Unit 42 researchers Xiao Zhang, Wenjun Hu, and Shawn Jin elaborate on this point in a blog post ,

All infected apps currently only require the INTERNET permission and are equipped with two activities, one is to load interstitial advertisements and the other one is to load the main app.

The latter one instantiates an Android WebView component and displays a local HTML  page. The WebView component has JavaScriptInterface enabled. This functionality isn’t used by the samples we’ve examined, but this enables loaded JavaScript code to access the app’s native functionality.
