Skygofree apparently has been around for a while but was a minor problem until recently. Now it is infecting more and more Android cell phones and tablet computers. The malware (malevolent software) has the ability to grab call records, text messages, geolocation, surrounding audio, calendar events, and other memory information stored on the device.
After manual launch, it shows a fake welcome notification to the user:
Dear Customer, we’re updating your configuration and it will be ready as soon as possible.
Then it steals your information and sends it to a server in an overseas location.
