The risk of not protecting your applications

As soon as you publish your application, even on official channels, you lose full control over the environment and security of your application.

An unprotected application can be affected by many security 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 an application is not obfuscated, it is extremely easy to decompile its apk, dll, exe or jar files and access the source code with decompilers such as IDA Pro, CFF Explorer, Scylla, DnSpy, Apktool, Frida.re and many more. A non-obfuscated application is the main gateway for decompilation. Once the application is decompiled, a hacker or cracker can reverse engineer and analyze its operation.

Penetration or tampering

Reverse engineering is not everything, especially in mobile or distributed applications. Having access to source code and not having security methods in place to prevent tampering, debugging or dumping is very dangerous. Competitors or attackers can alter processes, manipulate any part of the source code or even bypass licensing systems to get into your application.

How our Application Hardening and Shielding works

ByteHide Shield is not a simple obfuscation tool, it is a service that takes care of protecting your application from compilation to when it receives attacks in an untrusted environment.

Obfuscate your application with Multi-layer protection

Protect your application with different obfuscation techniques by hiding the logic and code of your application while maintaining its functionality. The different layers combine with each other to prevent an attacker from reverse engineering, analyzing the code or obtaining confidential information.

  • NAvoid reverse engineering
  • NProtects against intellectual property theft
  • NProtects against loss of revenue and damage to reputation

Secure against static and dynamic attacks with In-app protection

Code obfuscation alone is not enough, applications are exposed to different types of attacks, even if you publish it through an official distribution channel.

In-app protection combines different runtime protection methods, allowing your application to protect itself by detecting and mitigating attacks. This secures it in untrusted environments.

  • NPrevent your application from being tampered
  • NProtects against debugging, hooking and emulators
  • NProtects real-time in untrusted environments and detects jailbroken/rooted devices

Publish secure and robust applications, effortlessly for your developers

Shield is developer-first, integrates with the language or framework you use with a single click and requires no modifications to your code. Also it has CI/CD integration for your DevOps pipelines.

Your engineers don’t have to be security experts: configurations are simple, documentation is complete and the ByteHide platform integrates everything in one place for easy management.

Benefits of obfuscation and In-app protection with Shield

Never worry about reverse engineering again. Focus on your business and automate your software security.

Keep your intellectual property safe

Keep your application algorithms and data (which are important to your business) secure and hidden. Therefore, prevent crackers or competitors from analyzing, decompiling and stealing them.

Protect your source of income

Prevent attackers from cracking, exploiting or decompiling your application licensing or authentication system to gain unauthorized access that could severely damage your business.

Prevent your applications from cracking

Compiled programming languages are easy to decompile with some free and public tools. In client-side applications, it is very easy to manipulate security checks, illegally access paid features, bypass logins or licenses, or manipulate logic (cheat). This affects the experience of your legitimate users and gives your project a bad image.

Ensure integrity and lock out competitors

Do you know what it means if competitors, hackers or third parties can decompile .EXE, .DLL or APK files? It means that your intellectual property (IP) is at incredible risk of being stolen. As a result, they may be able to crack, clone and spread harmful copies of your program, causing damage to your customers, your business and your reputation.

Protect your applications easily

An obfuscator together with In-app protection is the most complete tool you will find to protect your applications easily and without the need to be an expert in encryption or cybersecurity. Keep competitors and hackers away from your app’s source code.

  • Protect against reverse engineering
  • Increase the security of your applications
  • Keep your intellectual property safe and away from crackers

Avoid decompilation and reverse engineering

Hardening and shielding applications will guarantee their integrity by keeping them functionally identical. It will prevent any attacker from cracking or reverse engineering your application and ensure that they cannot access the source code by decompiling it.

  • Prevent your applications from cracking
  • Mantain the security of your application always up to date
  • Protect your source of income from your competitors and hackers

Using ByteHide Shield to obfuscate applications in their compilation

Frequently asked questions about obfuscation and applications protection

What is obfuscation?

The term obfuscation is commonly used in cybersecurity to refer to making something difficult to read or understand. In the programming world, when the source code of an application is obfuscated it means that it is “modified” using renaming techniques and cryptographic algorithms to encrypt and harden. This obfuscation process is done to prevent the application from being reverse engineered and decompiled to avoid a wide variety of attacks.

Why should I obfuscate my applications?

Just as code once programmed becomes an application, that application can be reversed to get the source code of it. If the source code of this application is accessed without protection, shielding or obfuscation, its operation can be analyzed. This opens up many possibilities for attacks, both cracking and reverse engineering.

If an attacker accesses the source code of your application without obfuscation, he can actually completely modify its operation. In addition, it can steal intellectual property (IP) and cause a very bad image for a business or company, not to mention that there may be sensitive data (such as customer data, passwords or unencrypted database connections) that the attacker or competitor can easily access.

How can I obfuscate my applications?

There are actually many ways to obfuscate an application, from encrypting sensitive parts of the code, to replacing classes or variable names, to anti debugging or anti tampering techniques. All this is only useful if the person in charge of performing the obfuscation has advanced knowledge in logarithmic mathematics, encryption and cryptography. If not, anyone with a minimum knowledge in reverse engineering could reverse all the protections and access the source code. In that case the favorite and most powerful option is to use an obfuscator.

What is an obfuscator?

An obfuscator is a tool that analyzes your application, detects sensitive parts and through different obfuscation techniques increases the security of an application. The obfuscator converts the source code into code that is practically impossible to read by a human, but at the same time maintains its functionality at 100%. The recommendation we always make is the ByteHide Shield obfuscator because it offers military-grade encryption with super-simple preconfigurations. Literally anyone could protect their application with ByteHide Shield in 3 clicks!
