How to install IDA Free – Installation guide
Empowering analysts and security researchers, IDA Free stands as a potent tool for analyzing and reverse-engineering binary code. Esteemed among professionals, it garners popularity within the realms of security research and malware analysis. This blog post aims to illustrate the installation process of IDA Free and demonstrate its application in reverse engineering.
What is IDA Free?
IDA Free is a free version of IDA Pro, a commercial binary analysis tool. It includes most of the features of IDA Pro, but there are some limitations. For example, IDA Free does not support all processor architectures, and it does not have access to the Hex-Rays support team.
IDA Free is a free binary code analysis tool developed by Hex-Rays. It is a powerful tool that allows you to analyze both 32-bit and 64-bit applications, including features such as:
- Cloud-based x86/x64 decompiler: This feature allows you to convert binary code back into a more readable assembly language.
- Local x86/x64 debugger included: This feature allows you to step through the execution of a program and examine its memory and registers.
- Support for x86/x64 processors: This makes IDA Free compatible with a wide range of modern processors.
How to Install IDA Free
You can install IDA Free on any of the following: Windows, Linux, or Mac. In this blog, I’ll show you how to install this tool on Linux. To install this tool on Linux, follow the steps as mentioned:
- Download the IDA Free installer from the Hex-Rays website.
2. Click on IDA Free for Linux and wait for it to get downloaded.
3. After downloading, open a terminal, and navigate to the Downloads directory, and use the following command to extract it:
chmod 777 idafree83_linux.run
4. Now, to install the tool, we need to run the following command in that same terminal or in that directory where the tool is present.
./idafree82_linux.run
Then click forward -> accept the license -> keep the installation directory as default -> then it will install the tool. At last, click finish.
5. Now navigate to the default path where the tool is installed.By default, the path is: /home/kali/idafree-8.3/
6. Open a terminal in that directory. Now to run the tool, we need to use the following command:
./ida64
You’ve finally installed IDA Free, congrats!
How to Use IDA Free for Reverse Engineering
- Open a binary file
To open a binary file, click on the Open button in the toolbar. Select the binary file you want to analyze and click Open.
- Analyze the binary code
This tool will automatically analyze the binary code and display the results in the main window. The main window is divided into several sections:
- Disassembly: This section shows the disassembly of the binary code.
- Code View: This section shows the code in a more readable format.
- Graph View: This section shows a graph of the calls between different functions.
- Debugger: This section allows you to step through the execution of the program and examine its memory and registers.
- Reverse engineer the binary code
There are many different ways to reverse engineer binary code. Some of the most common techniques include:
- Identifying functions: You can identify functions by looking for patterns in the disassembly or by using a decompiler.
- Analyzing data structures: You can analyze data structures by looking for patterns in the memory layout or by using a debugger.
- Tracing execution: You can trace execution by setting breakpoints in the debugger or by using a debugger plugin.
