As smartphones have become an integral part of our daily lives, mobile apps have revolutionized the way we interact with technology. From controlling home appliances to managing security systems, mobile apps offer convenience and ease of access. ‘There is an app for that’ became a catch phrase and our dependence on them has grown very strong.

In 2019, app stores saw over 204 billion downloads with the large majority of downloads happening from the Google Play store. The average person today has over 40 apps on their phone but we only use an average of 30 apps per month. Collectively, Americans spent a total of 194 billion hours on apps in 2022!

However, with this increased connectivity comes the risk of mobile application privacy and security threats. In this article, we will explore various privacy and security threat mitigation resources to ensure the safety of our personal information and home devices.

But first, let us understand the various types of privacy and security risks that the mobile apps that we download onto our devices may expose us and our families to.

Mobile App Security Threats

Let us not forget that an app is really short for an application. Essentially, by downloading an app, you are installing a software program made by a third party vendor onto your device – and yes, the device is a computer. With this moment of realization in mind, here are some potential mobile security risks:

  • Even with the finest mobile application development, it may contain software vulnerabilities. Mobile app developers, despite their best intentions, are likely to make mistakes and those mistakes manifest themselves as exploitable bugs in the mobile app security. While many developers are good about catching these vulnerabilities and issuing patches, lots of developers are not. In fact, about 6% of apps on popular app stores have been abandoned by the developers who created them. If you have one of these apps then you are putting your device and your data at risk with an app that will never be updated to resolve the vulnerabilities.
  • A mobile app may utilize third party code that may have vulnerabilities. Many mobile app surveys, especially games and also apps that include ads use software libraries from third parties. The developers of these apps do not control the code that was used to create those libraries and hence cannot resolve bugs or vulnerabilities in those libraries. Multiple apps may also use the same libraries and hence the risk may not be limited to just one app. How would you know which app uses what third party software library? Well, you wouldn’t! This is a risk inherent in apps and one to be aware of especially in the context of permissions you give to the app.
  • A mobile app may collect sensitive data about you and your behaviors. Several mobile apps collect your geo-location or search history or browsing history or your personal information. We all agree to the various terms of service and privacy policies but over time, we have no visibility into which company has access to what kind of information about us. Further, many mobile apps share your information with third parties. Apps that are ad driven share your information with various ad networks and even data brokers. Even with the highest level of security, a data leakage may occur as result of security vulnerabilities exploited by hackers.
  • Mobile apps may communicate with other devices in your home network. Some apps control devices in your home like your home internet router, lightbulbs, thermostats, etc. While these are useful, it is also important to realize that these apps are able to control those devices because of data access they have opened up to those devices. This access can be exploited by malicious actors and hackers as well, if it is not properly protected.
