This isn’t good. According to multiple sources there is a botnet full of android users out there with a fake yahoo app. What is a botnet? Usually a large group of infected computers is called a “botnet”. These infected devices are used to send infected email that can have spam links and virus links.
It looks like someone figured out how to fake the yahoo mail for android app. Although it is not on Google play, anyone who can’t use Google play might have installed the trojan somewhere else. At any rate these android users are now unknowingly sending spam emails to others. Not good. Please think twice before you download an app not from Google Play. If your android device is not authorized by Google then just be careful in general.
