Best Xamarin obfuscatorwith military-grade protection

Launching a Xamarin application or publishing it in the app stores can be scary. Once you release your application, it becomes freely available to everyone and you completely lose control over it. Protecting your Xamarin apps is vitally important to prevent decompilation and reverse engineering by attackers and competitors.

Xamarin applications without obfuscation

Once you release a Xamarin application to a public app store, you lose control of it.
An unprotected Xamarin application can lead to many serious problems.

Vulnerability detection

Without source code encryption, vulnerability analysis can be performed and bugs can be discovered, allowing the application to be exploited directly.

Damage to brand image

An exposed, vulnerable or cracked application generates a huge distrust to your end users, damaging your brand and revenues. If your application is insecure, your users' data is also insecure.

Cracking and Reverse-engineering

Just by analyzing the unprotected source code of the application, an attacker can understand its operation and crack it directly without manipulating it.

Intellectual Property (IP) Theft

This is the biggest problem. After all the money and time invested in the research and development of your app, any attacker can steal or clone your whole software in a few seconds.

Reverse engineering

If a Xamarin application is not obfuscated, it is extremely easy to decompile its apk and dll files and access the source code with free .NET decompilers such as DnSpy or ILSpy. A non-obfuscated Xamarin application is the main gateway to decompiling. Once the application is decompiled, a hacker or cracker can reverse engineer and analyze its operation.
  • Analyze its classes, methods and how the application works
  • Access to important or sensitive parts of the source code
  • Modify the application's functionality or injecting malware

Penetration or tampering

Reverse engineering is not everything, especially in mobile applications like Xamarin. By having the source code unprotected and being able to access it, competitors or attackers can alter processes, manipulate any part of the source code or even bypass licensing systems or login your application.
  • Data theft and capture of communications
  • Vulnerability scanning and intellectual property loss
  • Circumvent security checks or execute piracy

Frequently asked questions about obfuscation and protection of Xamarin applications

What is obfuscation in Xamarin?

Obfuscation in Xamarin is the process in which the compiled application is encrypted, hardened and secured using cryptographic algorithms and renaming techniques. This obfuscation process prevents the protected application from being decompiled and analyzed, avoiding potential reverse engineering attacks that can result in intellectual property (IP) theft.

Why should I obfuscate my Xamarin applications?

When developing an application in Xamarin (.NET Framework), the source code is compiled into IL code (no native code) and this process can be reversed. It is very easy to convert the compiled code into readable code again at runtime. This way if the source code is not protected or obfuscated, anyone with minimal knowledge can analyze and exploit a Xamarin application.

Moreover, mobile operating systems such as iOs, Windows Phone or Android do not enable any kind of active or passive security at application runtime, exposing it to a wide variety of attacks and vulnerabilities of the operating system itself.

How can I obfuscate my Xamarin applications?

There are many tutorials that explain how to obfuscate your application assemblies but this is far from certain. Without advanced knowledge of encryption, cryptography and algorithmic and logarithmic mathematics, a person with a background in reverse engineering can easily reverse these protections.

Xamarin-based mobile application projects (no matter if they run on Android, iOs or Windows Phone), should be obfuscated with a Xamarin obfuscator. There really aren't many obfuscation options. The best recommendation is ByteHide Shield due to its simplicity, price and military grade security level.

What is a Xamarin obfuscator?

A Xamarin obfuscator is a tool that performs a combination of code optimization and shielding to prevent the application from being tampered with or modified. The source code is transformed into human-unreadable code while maintaining all the functionality of the original application. This way you guarantee the security of your Xamarin application on any device with any operating system (Android, iOs or Windows Phone).
