The malwares are being spread through false apps to free up memory of the devices and enhance their performance. They were available at Google Play as Superclean (published at January 3rd and got 4,5 stars with more than one thousand installations) or DroidCleaner, both from Smart Apps developer. Both apps were not blocked by the protection system of Google Play, although they were removed some time after that. They still could be available for download in smaller stores.

When installed, the apps ask for a group of permissions from sending SMS to enable the WiFi network, handle the owner personal data including SMS, photos, contacts, GPS coordinates and also any data or file in the SD card!
