Symantec researchers report a group of 25 malicious Android applications available through the Google Play Store to Google. In total, the applications had been downloaded more than 2.1 million times from the store. The apps would conceal themselves on the home screen some time after installation and begin displaying on-screen advertisements even when the applications were closed.

Most of the applications claimed to be either photo utilities or fashion-related.”]
