Antitamper Mobile - Minded Security's Magik Quadrant for Mobile Code Protection (2018 Edition)


Minded Security's Magik Quadrant for Mobile Code Protection shows our evaluation of the top vendors in this market, based on our research and experience, updated to 2018.

Magik Quadrant

 

Why care about Code Protection?

The main reason lies in the fact that Mobile Applications runs within an environment that is not under the control of the organization producing the code.

Lack of Code Protection could have the following consequences:
  • Malicious users or competitors could decompile the application and gain knowledge about proprietary algorithms or intellectual property
  • Using this information, it could be possible to modify the code, repackage it and redistribute it to create a "trojanized" clone of the App
  • Revenue loss due to piracy
  • Reputational damage

Since 2016, the OWASP Mobile Top 10 has included two new categories related to that, that is M8-Code Tampering and M9-Reverse Engineering.

Code Tampering

Code Tampering is the process of changing a mobile app (either the compiled app or the running process) or its environment to affect its behavior.
The most common code tampering techniques are:
  • Code Injection
  • Binary Patching
  • Local Resource Modification
  • Method hooking
  • Method Swizzling
  • Dynamic Memory Modification  
Tools and frameworks like Frida, Substrate, Cycript, Xposed and FLEX could give an attacker direct access to process memory and important structures such as live objects instantiated by the app. 
They come with many utility functions that are useful for resolving loaded libraries, hooking methods and native functions, and more.
This can provide the attacker a direct method of subverting the intended use of the software for personal or monetary gain.

Code Tampering could be prevented by detecting at runtime that code has been added or changed since compile time.

Reverse Engineering

Reverse engineering a mobile app is the process of analyzing the compiled app to extract information about its source code. 
An app is said to be susceptible to reverse engineering if an attacker can derive a reasonably accurate reconstruction of the source code from the binary.
Reverse Engineering could be prevented by using an obfuscation tool that implements controls like:
  • String Encryption
  • Name obfuscation
  • Control flow obfuscation
  • Arithmetic obfuscation


Also to that, it is important to implement anti-debugging techniques and verify if the application is running on a rooted/jailbroken device.


Some commercial tools provides code protection without requiring developers to implement their own custom controls.
The remaining of this blog post is going into details about the tools available in the market in 2018.

Interpreting the Magik Quadrant

The Magik Quadrant study performed on Code Protection solutions takes into account multiple criteria based on Ability to Execute and Completeness of Vision.

Ability to Execute
Vendors must deliver strong functionality in the following areas of capability:
  • Techniques implemented
  • After Sale Support

Completeness of Vision
Completeness of vision in the Code Protection market considers a vendor’s vision and plans for addressing buyer needs in the future:
  • Cross-platform support
  • Innovation
  • Sale Strategy

Before proceeding, it is worth noting that focusing on the leaders' quadrant isn't always the best choice. There are good reasons to consider market challengers. Moreover a niche player may support a specific needs better than a market leader.


Leaders
Leaders offer products and services that best cover current scenarios and are well positioned for the future. They provide solutions that are cross-platform, so with one vendor is possible to protect many platforms. Their complex solutions provide protection (through obfuscation, encryption, call hiding etc.), detection and reaction (in case an attack is detected).

Visionaries
In general, in any Magik Quadrant the Visionaries are the innovators. They understand well where the market is going and therefore they can provide innovative techniques to protect the applications in a cross-platform environment.

Niche Players
Niche Players, in our research, are vendors that do not offer, at the moment, a cross-platform solution but they are focused on a small segment. Since they are offering platform-specific solutions, in some case they are able to provide innovative and specific solutions for that specific target.
