Code obfuscation prevents any unauthorized party from accessing and gaining insight into the logic of an application, which prevents the attacker from extracting data, tampering with code, exploiting vulnerabilities, and more.

The Problem

Mobile applications can be reverse engineered using readily available disassemblers and/or decompilers, making it easy for hackers to access and analyze the source code of your applications. Hackers can then:

  • Steal intellectual property & clone applications
  • Extract sensitive information & harvest credentials
  • Identify vulnerabilities
  • Add malicious code to apps & repackage them

Data of a sensitive nature may include; valuable intellectual property (such as custom algorithms), authentication mechanisms, in-app payment mechanisms, keys (API keys, hardcoded encryption keys etc.), credentials (database passwords etc.), the logic behind server communication, and much more.

Why use code obfuscation?

All of this is undertaken without altering the function of the code or the end user experience in a meaningful way.

Code obfuscation strategies include:

  • Renaming classes, fields, methods, libraries etc.
  • Altering the structure of the code
  • Transforming arithmetic and logical expressions
  • Encryption of strings, classes etc.
  • Removing certain metadata
  • Hiding calls to sensitive APIs, and more

Mobile application obfuscation prevents hacking

Code obfuscation is a technique of mobile app protection that is used to enhance the security of the software by making it more resistant to reverse engineering and unauthorized modifications. The goal is to delay hackers attempting to understand how the code works.

Types of obfuscated code

There are several techniques available today to obfuscate code. These include:

Name obfuscation

The replacement of readable names in the code by difficult to decipher alternatives

Control flow obfuscation

The modification of the logical structure of the code to make it less predictable and traceable

Arithmetic obfuscation

The conversion of simple arithmetic and logical expressions into complex equivalents

Code virtualization

The transformation of method implementation into instructions for randomly generated virtual machines
