McAfee uncovers Android apps on the Google Play Store that drain battery with fraudulent ads running in the background.

FULL STORY ======================================================================

Android apps with millions of downloads have been found running ads constantly, draining battery and causing all sorts of other problems for users.

The Mobile Research Team at antivirus vendor McAfee discovered 43 apps of
this kind and reported them to Google for violation of Play Store policies. They have now been removed from the store.

The apps, usually streaming or news based in nature, mainly targeted Korean users. The adware they contain can lead to users being profiled, as well as consuming their data and draining their battery. Invisible adware

The adware doesn't strike immediately; instead, it waits several weeks before becoming active, in an effort to evade detection by users and Google themselves.

McAfee also found that the operators behind the adware can control remotely its configuration, such as when it is deployed and so on. read more

In order to bypass Android's power-saving feature, which prevents apps from running processes in the background while the device is dormant, the adware prompts users to exclude the app from this.

If excluded, then the adware will load ads even when users are not using
their device, in order to maximize revenue from ads fraudulently. Users are not even aware this is happening, allow McAfee notes that it may be possible for them to quickly see an ad when they go to check their phone again.

However, they main way to tell whether you have been infected is by checking if you battery is draining more than usual when you are not using it. In the battery settings of Android devices, you can see how long an app is consuming battery power in the background for.

According to McAfee, the apps also request permission to draw over other
apps. This is a method used by many other malicious apps that want to steal valuable data, as it allows them to overlay phishing pages on top of legitimate apps. However, the adware in this case exhibits no phishing attempts.

McAfee advises to carefully check apps before you download them, and pay attention to when they ask you for certain device permissions, such as overlaying and excluding from battery saving implementations - these do have legitimate uses in the case of many apps, so think about whether it is necessary. It is also prudent to check review scores from other users. These are the best Android antivirus apps around
