Introduction

What is Frida?

Frida is a dynamic instrumentation library designed to work on multiple platforms and architectures such as Android, iOS, Windows, Linux, etc.

It serves multiple purpouses such as:

• Blackbox testing of precompiled binaries
• Inspect a process memory, imports and exports
• Dynamically modify the process behaviour (Function hooking or override)
• Add new behaviour to the application
• Inspect method calls and view or modify its parameters
• Have fun!

All of this can be done using JavaScript, but bindings for multiple languages like Python, C, Swift, .Net, etc are available.

Installation

Usually, you would want to install frida-tools to have a CLI interface for fast prototyping and other useful tools:

pip install frida-tools

Also, you can install just the frida core [1] and use it directly from a python script. This is particularly useful when developing new tools, snippets or entire application that work on top of frida

pip install frida
