How the app can be used?
First you need to download the application and install it on the device on which you want to spy. After installing an application you need to register it. Next, you need to go to http://smstracker.com, where you will be asked for your login name and password, which was registered at a time of installing the application.
This screenshot shows the dashboard after login.
This screenshot shows the page where you can see logging from the device. It covers SMS, device information, call logs, network traffic, location details, etc.
This same application could also serve generic template for other spyware projects by being wrapped with other code to provide the core functionality needed to create another malicious app. This type of app clearly shows the powerful level of access that can be granted to Android apps, so long as users grant permission. An app can access SMS, call logs, network traffic, hardware details, screen details etc. Always carefully read the permissions requested by an application before installing it on your device.
The vendor is promoting this application as a tool for monitoring the mobile activities of your children. However, this same app would be a very effective tool for spying on someone once installed on their phone. You just need to install the app on the device which you want to spy and you are done. All the information about the device and all call and SMS logs can then be remotely monitored.
Moreover, all of the user’s private data is stored on the vendor’s server. What guarantees are in place that the private data will remain private? In the increasingly common enterprise world of “Bring Your Own Device” (BYOD), such applications could be leveraged to expose corporate contact lists, email, browsing information and collect private data from corporate apps in the workplace. Enterprises often block access to ‘non-official’ app stores to prevent the installation of such apps, but this illustrates that such a restriction is no guarantee that spyware can’t be installed from an official source.

Interestingly, despite virtually the same functionality, far fewer AV vendors flag the Google Play version as malicious.
