Top Mobile Apps Security Blunders That Can Put You In A Dilemma

Mobile apps have successfully entered our day-to-day lives and contain a huge amount of our secretive data, and even a little mistake by the developer can cost a lot to the user. As more and more apps are being launched on an everyday basis, the competition is getting fierce, and that has lead to the development of more sophisticated apps. However, because of this competition and the urge to get on the top, developers sometimes commit mistakes that take the shape of blunders in the future. Just a tiny mistake and lack of proper testing can develop and malicious app which, after being downloaded, can infect the device. But what is more dangerous is a hacker finding the app’s loophole and then using it as their advantage to access the device and extract crucial information from it. So in order to not make these mistakes, a developer needs to first know about such mistakes. And in this article, we will be exploring the same.

Top Mobile App Security Blunders

Data Encryption

Data Encryption is probably the most important thing that a developer needs to add in any app, especially if the app is used to share crucial data by the users. However, surprisingly, very few apps come with the feature of data encryption. A number of mobile apps are used to share sensitive data between the application and the server. This is what hackers keep looking for. The apps that don't have data encryption keep falling as victims to hackers. In order to prevent such attacks, it's important for developers to include any kind of encryption systems like SSL protocol or anything else. 

Weak Passwords

Poor passwords are undoubtedly the most common reason behind security breaches. It's a fact that most of the people keep a very weak password or keep using the same password everywhere. This, in turn, becomes a great cause of security breaches. So how to deal with it? Don't let your users use weak passwords. Ask them to use passwords that contain various things like numbers, capital letters, special characters, etc. In this way, the password will be difficult to crack, plus it wouldn't be their common password.

Storing the Same Password in Text 

Once your user has chosen the password, it becomes your responsibility to keep it secure. Now what most of the developers do is save it in clear text format that is the same password the user used. In such cases, whenever a security breach happens, the hackers will immediately get access to usernames and passwords. In order to protect these crucial details, developers should preserve the credentials in an encrypted format. 

Missing Front-End Validation

Missing front-end data can lead to both security and formatting issues. 

These might be things like giving alphanumeric qualities access numeric fields, missing veiling on arranged fields, not checking for high-hazard character esteems, for example, <>' " ()|#

Such missing approvals may cause security ruptures by permitting remote code execution or surprising reactions.

Using Third-Party Codes

Sometimes it becomes vital to use third party codes in an app in order to make it a market-ready app; however, third party codes come with their own set of vulnerabilities that can put the user data at risk. Third-party codes have their own features that add up to the app’s basic functionality and so abandoning these might not be the solution here. So what to do instead? Developers need to understand the functionality as well as the guidance surrounding the third-party codes. This will allow the developers to use the codes fearlessly and will also not harm user security.

Inadequate Security Testing

Developers often neglect to do perform rigorous app testing before finally launching the app, which might not be the best thing to do. Your app needs to be completely market-ready, especially in terms of security before going public. And that’s where testing is critical. Testing should be done to explore the vulnerabilities of the app. It should go through a “penetration test” of the app by some app security experts. A web app penetration test is the process of detecting an app’s vulnerabilities by stimulation unauthorized attacks for accessing sensitive data.

Unnecessary Features

To develop an app that can top the charts is definitely a challenging task, and that’s why developers add a bunch of unnecessary features to lure new users. However, these unnecessary features don’t only confuse the users but also make the app more vulnerable to security breaches. Also, if more private data is accessed and utilized by the app, the damage made by any security breaches will be a way more. 

Storing Data in The Device Memory

This is one of the most common mobile app security mistakes. Many crucial data like credentials, encryption keys, and even payment details are stored in the mobile device, which can be a great issue if the device gets in the wrong hands. The issue is even worse when the local storage is shared by some other applications as well. If a breacher somehow gets access to one application, they will eventually get access to all the stored data. So it’s better not to store data locally but to access the data only when the user logs in and erasing it once logged out. In this way, the data will be stored in the cloud and not the local storage.


Mobile apps have become an integral part of almost everyone’s life, and if a developer wants to develop an app with the aim of getting into the mobile phones of millions of people, security should be their priority. After all, from shopping online to sending payments, mobile apps are used for plenty of tasks. The best way to avoid future security breaches is by supposing that the app will eventually get breached. With this mindset, the developer will start to take security measures as much as possible. In this way, the developer will be able to build a security system from the start, test the app multiple times for detecting the loopholes, and then plan for the worst cases.
