Your Android Apps Are Leaking Privacy Data Without Your Knowledge

Your Android Apps Are Leaking Privacy Data Without Your Knowledge. There are chances that you most likely are hack with your installed apps.

Something as simple as changing your Android phone’s wallpaper or downloading a ringtone could leak your personal data. Your personal data may be your location, without your knowledge.

According to the researchers, “About 15 of 30 randomly selected, popular, free Android apps sent users’ private information to remote advertising servers and two-thirds of the apps handled data in ambiguous ways”

The researchers at Duke University created a tool called TaintDroid that identifies apps broadcasting private data to distant locations. TaintDroid monitors how applications access and use your location, microphone, camera, and phone numbers in your contact list. The tool also provides feedback once an app is newly installed, for telling you know if the app is transmitting data.

“This automatic feedback gives users greater insight into what their mobile applications are doing and could help users decide whether they should consider uninstalling an app,” says Peter Gilbert, a graduate student in computer science at Duke University who is working on this project. The TaintDroid program is not publicly available.

You might be concerned with your private data in your android. There are chances that you most likely are hack with your installed apps. A simple mobile app which looks risk-free on the outside leaks your private data. This is not rumor, it can happen to anyone.


According to a recent infographic released by research firm Zscaler a lot of apps on both Android and iOS may be leaking your private data from you android phones.

Types of private data:

According to the infographic, there are 3 types of private data that are, Location data, device metadata and personally identifiable information (PII). The location data is self descriptive, while the device metadata is information about your device’s company and model and the real danger is the outflow of the PII.

PII is data about you explicitly. It includes the phone number you use on your smartphone, your email address and it could be your fingerprint as well, if your phone has a fingerprint scanner.

Data outflow statistics:

Bbout 0.5% of iOS devices leak sensitive data (all 3 types of private data that mentioned above). Android devices relatively leak 0.3% of sensitive information. Both the platforms, majority of it are location data or device metadata.

Android devices expose more (3%) of personally identifiable information compared with iOS devices (0.2%).

The state where the information leaks is also remarkable. Most of the data leakage on Android devices occurs in US and UK with other countries contributing fairly small shares to the total leakage on Android.


For iOS, most of the leaks came unexpectedly from China. This was followed by South Africe (ZA) which is also unexpected. All in all, these 2 countries contributed to 90% of data leakage on iOS devices.


How to be secure?

Always ensure the publisher of the app that you are going to install. Some shady publishers can find their way on to the app stores of both of the platforms android and iOS. Good security practices should always be followed despite of data leakage.
