Hybrid mobile app frameworks such as; React Native and Cordova make life easier for developers as they can write code once and build apps that run on the leading mobile OSs with no extra effort. The app will run on Android and iOS, and the code can be reused for PWAs (progressive web applications).
What are the consequences?
- Your code can be copied and used without permission
- It makes your code vulnerable to hackers
- Your app’s functional logic on the client-side and algorithms are exposed.
JS obfuscation is a series of code transformations that turn exposed code into a modified version that is hard to understand and reverse-engineer. This way, you ensure that your product’s intellectual property is protected against security threats, the discovery of app vulnerabilities, and unauthorized access.
When your app’s code is obfuscated, an attacker’s threshold to carry out a reverse engineer-attack is significantly increased, as it will often be too time-consuming and costly to succeed.
Script before JavaScipt obfuscation
With a series of code transformations, your exposed script is made more difficult to analyze, understand and reverse engineer.
By adding runtime protection to your app, your app can detect and protect against tampering or malware attacks. Sophisticated mobile malware exploits various security vulnerabilities in the mobile OS and uses diverse techniques to achieve its key goals. For example, Malware can misuse the Android Accessibility APIs to attack your app.
Anti-tamper controls also make your app able to detect emulators/debuggers and tampering attempts and prevent attackers from analyzing or modifying your code at runtime. The technique checks its own code to ensure the app is in its original state, and if attackers are using malware or code tampering software to enter the app, runtime protection techniques will detect and block it.
Utilizing code obfuscation combined with a multi-layered app shielding solution will make your apps less prone to reverse engineering and intellectual property theft.
