Trend Micro researchers have spotted two apps that have been equipped with cryptocurrency mining script.
Researchers at Trend Micro found three programs available for download in the application souk that were surreptitiously using the spare CPU cycles on people’s smartphones to mine Monero, using code built by Coin Hive. The mining apps were variously disguised as a wallpaper collection, a wireless safety app, and software to help Catholics with rosary prayers.
The first (prsolutions.rosariofacileads) is an app that is meant to help users pray the rosary, the second one (com.freemo.safetyne) allows users to “earn free Talk, Text, and Data” by racking up credits “by redeeming local coupons and deals, watching videos, taking surveys and more.” , the third is a legitimate wallpaper app (com.yrchkor.newwallpaper) that has been modified to include a mining library.
First two apps have been pulled from Google Play, and the accounts of their developers have apparently been removed or suspended. They can still be downloaded from some third-party Android stores.
