"description": "Chamois is one of the largest PHA families in Android to date and is distributed through multiple channels. While much of the backdoor version of this family was cleaned up in 2016, a new variant emerged in 2017. To avoid detection, this version employs a number of techniques, such as implementing custom code obfuscation, preventing user notifications, and not appearing in the device’s app list. Chamois apps, which in many cases come preloaded with the system image, try to trick users into clicking ads by displaying deceptive graphics to commit WAP or SMS fraud.",

In some cases, BreadSMS apps also implement subscription-based SMS fraud and silently enroll users in services provided by their mobile carriers. These apps are linked to a group of command-and-control servers whose IP addresses change frequently and that are used to provide the apps with premium SMS numbers and message text.",

These apps disable Wi-Fi to force traffic to go through users' mobile data connection and then contact command-and-control servers to dynamically fetch code that tries to bypass the network’s WAP service subscription verification steps. This type of PHA monetizes their abuse via WAP billing, a payment method that works through mobile data connections and allows users to easily sign up and pay for new services using their existing account (i.e., services are billed directly by the carrier, and not the service provider; the user does not need a new account or a different form of payment). Once authentication is bypassed, JamSkunk apps enroll the device in services that the user may not notice until they receive and read their next bill.",

Expensive Wall apps use code obfuscation to slow down analysis and evade detection, and rely on the JS2Java bridge to allow JavaScript code loaded inside a Webview to call Java methods the way Java apps directly do. Upon launch, Expensive Wall apps connect to command-and-control servers to fetch a domain name. This domain is then contacted via a Webview instance that loads a webpage and executes JavaScript code that calls Java methods to compose and send premium SMS messages or click ads without users' knowledge.",

In a second stage, BambaPurple installs a backdoor app that requests device admin privileges and drops a .dex file. This executable checks to make sure it is not being debugged, downloads even more apps without user consent, and displays ads.",
