Some great IT geniuses have developed new software that shows if whether an app has accessed private data of the user to spy on the user. Apps on Internet enabled mobile devices can be used to spy on their users, so Computer researchers from Germany have developed the new software to track malicious activity if any by apps.

At the end of last year around the month of July the Russian software       company “Doctor Web” detected several malicious apps in “Google Play”. Downloaded on a Smartphone, the malware installed – without the permission of the user – additional programs which sent expensive text messages to premium services.

Although Doctor Web, according to its own statement, informed Google immediately, the malicious apps were still available for download for several days after the complaint was registered. Doctor Web estimates that up to 25,000 Smartphones are used fraudulently.

The new software can discover such malicious apps already in the app store. The software detects pieces of code where the app can access sensitive data and where data is sent from the mobile device. If the software detects a connection between such a “source” and such a “sink”, it reports that as suspect behavior.

To identify a functional relation between source and sink, the computer scientists use new methods of information flow analysis. As input they provide suspicious combinations of accesses on the application programming interface. As the software needs a lot of computational power and storage, it runs on a separate server.

So far up to 3,000 apps have been tested with it. The software analyses them fast enough that the approach can also be used in practice, say some reporters.

New Software Catches Spying Apps
