In today’s digital age, mobile apps are in charge of everything, from banking to shopping to health care. But as more people use it, the hazards to security grow. Mobile app penetration testing will no longer be a possibility in 2025. Businesses that care about user safety and trust must do this. This testing process puts real-world cyberattacks to the test to find holes before hackers can use them.
By doing both mobile application security testing and network security testing, developers can find hidden bugs and protect both the app and the data. We give the impression of being at the most widespread security problem found and how to solve them with uncomplicated, effective actions below.
Storing Data in an Unsafe Way
A lot of mobile apps keep user data on the device itself. One of the most common problems with mobile app security testing is storing data in plain text. Attackers often go for cached files, shared preferences, or databases, especially on devices that have been rooted. They can get the data with simple tools if it isn’t safeguarded. To remedy this, developers should always utilise encryption like AES-256 and not store sensitive data until they have to. You should also utilise secure key storage tools like Android Keystore or iOS Keychain.
Weak Controls on the Server Side
Apps commonly link to back-end servers to get or save data. If the security on the server side isn’t strong, hackers can skip the app and go straight to the source. Mobile App Penetration Testing often finds this flaw. Authentication problems, bad session handling, and not having access control are all common problems. These problems permit those who shouldn’t have access to restricted data or do things they shouldn’t. The solution? Always check the inputs from users on the server, make sure that role-based permissions are in place, and protect API tokens.
Network security testing also looks for flaws in the communications between the app and server.
Unsafe Ways to Talk to Each Other
Apps need to talk to servers to work, but this talk has to be safe. Hackers can get data communicated across insecure channels by utilising public Wi-Fi or fake networks. Apps should always utilise HTTPS with TLS 1.2 or higher to stop this from happening. SSL pinning assists in keeping individuals by means of false certificates. One of the biggest hazards that network security testers look for is this weakness, which they find by pretending to intercept real-time communication. Also, make sure that sensitive data is never logged or retained while it is being sent without encryption.
Authentication and Authorization that aren’t done well
Some programs let you use weak passwords, don’t retain login sessions safely, or don’t check user roles correctly. These are sure symptoms that security requires improvement. Testers look for issues in mobile apps that allow hackers get in devoid of the correct credentials or see data.
To fix such issues, ensure passwords are strong, and two-factor authentication is always on. The server side must for all time manage authentication, not the client end. For all time do it on the server side. Also, checks for authorisation should be based on roles and checked at every step.
Reverse Engineering and Changing Code
If mobile apps aren’t protected, they can be decompiled and changed. Hackers do this to get keys, add bad code, or get around login systems. You’re in danger if your app includes sensitive data or logic inside it.
Mobile App Use Reverse engineering is a common way for testing tools to find these kinds of vulnerabilities. Obfuscation tools should be used by developers to make code hard to read and hard to get out. App integrity checks can also tell whether someone has messed with the app.
Bad logging and error handling
Network security testing often finds hidden logs or long server faults. To remedy this, don’t keep track of your personal or financial information. Users should only see basic error messages, and full records should be kept safe and encrypted. Also, make sure that logs don’t linger on devices longer than they need to.
Conclusion
The mobile environment is getting bigger, and so are the risks. Testing early, often, and quickly is the best approach to keep safe. Developers can find real-world threats before users ever see them by doing both mobile app penetration testing and mobile application security testing.
Testing network security is excellent for app security since it keeps the data flow between the app and the server safe. These strategies work together to make sure that users can trust and depend on their mobile experience. Are you ready to protect your mobile app?
