7 Threats to mobile app security and why it’s so important to prevent them



Do you have a small business? Are you worried about threats to your app security? Well we’re here to help.

Even to app developers, the prospect of hackers is undeniably daunting but at Voosh, we have the right experience and understanding needed to keep your app safe. With almost half (42 percent) of businesses using apps (Clutch 2018), there’s a huge market for hackers to attack.

The number of fraudulent cases that occur over apps have soared across the last few years. In 2019, fraudulent app installs spiked from 16.6 percent to 22.6 percent in just five months (Total Retail 2019).

According to Positive Technology (2019), high-risk vulnerabilities were found in 38 percent of mobile applications for iOS and in 43 percent of Android applications.

This is why it’s important to spend time making sure your app is protected. If you’re interested in the threats that are posed to mobile applications, then look no further!


1. Unprotected Storage of Sensitive Data

According to Security Today in 2019, three quarters of mobile applications have vulnerabilities that could allow hackers to steal sensitive information from both Android and Apple. Mobile apps, especially shops and purchasing platforms, often store sensitive data such as bank details, pin codes and other passwords. This must always be stored encrypted to prevent data that is stored within the software to be retrieved.


2. Apps Without Multi Factor Authentication

Ultimately, apps need multi-factor authentication because you can’t force people to use different passwords for all the third-party services used by your company! We know that most of us are guilty of using the same varying password across multiple shops and websites but this is exactly how fraudsters strike.

Once a fraudster has a user’s password from one website, they are likely to test the password on all other apps. So even when your business may have not been the first one to be breached, it doesn’t mean it won’t be the last.



3. Hardcoded Passwords

Hardcoded passwords are plain text passwords or other sensitive information that can be found in source code. It is sometimes used by developers as a shortcut to make applications easier to debug or support. Once hardcoded passwords are discovered it provides security of the application or the systems it authenticates to with this password ineffective.



4. Reverse Engineering

Reverse engineering is the process of taking something apart to see how it works, whether it’s a physical object or in this case, a mobile application. Reverse engineering can be used to understand how your technology is working and individuals do so to seek algorithms and other threatening things. Essentially, without the proper protection, your application’s own code can be used against you.



5. Data Storage

Once hackers have access to a mobile application, a device or a type of database then they have the ability to access all information and transfer it to their own devices and machines. A lot of the time, insecure data is caused by a lack of handling of cache of data, images, and key presses.



6. Sensitive data leakage

Data leakage is the unauthorised transmission of data from within an organisation to an external destination or recipient. Sensitive data leakage can be either inadvertent or side channel. Data leakage threats usually occur via the web and email, but can also occur via mobile data storage devices such as optical media, USB keys, and laptops.



7. Improper Encryption

Encryption is the method by which information is converted into secret code that hides the information's real meaning. So, if your encryption codes are compromised then it’s very difficult for your online business to remain safe. If your encryption codes are compromised then hackers will be readily available to your information, in plain sight!

For these reasons, it’s absolutely crucial to find a developer that treats app security as the highest priority. We know how fundamental it is to keep your customers feeling safe and secure when engaging with your brand.
