Setting Up a Secure Malware Analysis Environment: A Step-by-Step Guide for Beginners

Introduction

Malware analysis can be a daunting task, especially when faced with the complexities of modern threats like RedTail. For those new to cybersecurity or malware analysis, understanding how to approach the problem and what tools to use is crucial. When Jacob Claycamp, an ISC intern, first encountered malware being uploaded to his honeypot, he quickly realized the importance of using the right setup for effective analysis. In this guide, Jacob shares his journey in setting up a secure and isolated malware analysis environment using Remnux, a Linux-based distribution for malware analysis, alongside Docker and AWS EC2 instances for cloud-based containment and safety. Through this, Jacob walks you through the process of creating a controlled environment for analyzing malware like RedTail and using effective analysis tools.

Setup Overview

To set up a safe and effective malware analysis environment, Jacob recommends using the Remnux distribution combined with Docker and AWS EC2. Here’s a breakdown of the necessary steps:

Launch an EC2 Instance in AWS: The first step is to create an AWS EC2 instance with the necessary resources, such as 2 vCPUs, 16GB of RAM, and 100GB of disk space. These specs ensure you can run the Kasm Workspaces and Remnux without issues.
Install Kasm Workspaces: Kasm is a Docker-based platform for managing virtual environments. After deploying an Ubuntu 20.04 instance, you can install Kasm and configure it for running malware analysis workspaces.
Deploy Remnux in Kasm Workspaces: With Kasm installed, you can add the Remnux workspace, which comes with a wide range of malware analysis tools pre-installed. The process is straightforward and involves adding Remnux from the Kasm registry, installing it, and enabling it.
Upload and Analyze Malware: Once the environment is set up, you can begin uploading malware samples like RedTail. Jacob emphasizes the importance of both static and dynamic analysis for effective malware investigation. For static analysis, tools like “file,” “Detect It Easy” (die), and UPX help unpack and identify key details about the malware. Dynamic analysis can be performed using Ghidra, a powerful tool for disassembling and analyzing complex malware.
Tools for Deeper Analysis: Jacob explains that Ghidra provides an excellent way to dive deep into the malware’s code, offering insights into its structure, function calls, and behavior. Despite the complexity of the RedTail sample, Ghidra allows analysts to decompile, debug, and track the malware’s evolution over time.

What Undercode Say:

Setting up a cloud-based malware analysis environment with tools like Remnux, Docker, and AWS EC2 is a smart move for anyone serious about cybersecurity. Not only does this setup provide a secure sandbox for testing and analysis, but it also offers scalability, ensuring that as threats grow in complexity, your analysis environment can grow with them.

Why Use Docker and Cloud for Malware Analysis?
Docker and cloud environments are ideal for malware analysis due to their ability to isolate the malware from the host system. If the malware accidentally detonates, the container can be easily destroyed and recreated without any impact on the main system. This method reduces the risk of exposure and allows for safe, repeatable experiments.

2. Security Concerns with Remote Workspaces

By using AWS EC2 and Kasm Workspaces, malware analysts can ensure that their local systems are protected from potential attacks. Running Remnux and other malware tools in a virtualized, cloud-based environment mitigates the risks of malware infection on personal or company devices.

3. Static vs. Dynamic Analysis: A Balanced Approach

Jacob correctly emphasizes the importance of both static and dynamic analysis. Static analysis helps you understand the core structure of the malware—its file format, compiler, and embedded code—while dynamic analysis allows you to observe the malware in action. This combination is crucial for gathering comprehensive data on how malware operates and spreads.

4. Practical Applications of Malware Analysis

For anyone looking to go beyond basic analysis, Ghidra is invaluable. It offers an in-depth look at a malware’s code and functionality, making it easier to trace its actions and understand its objectives. This is particularly useful when examining more sophisticated malware like RedTail, which can evolve and modify itself over time.

5. Malware Evolution and Mitigation

As Jacob points out, many malware samples are modified versions of existing code. By analyzing malware over time, researchers can track these changes and identify emerging threats. This ongoing research helps the cybersecurity community better defend against future attacks by understanding how malware evolves and adapts to bypass defenses.

6. Key Tools and Resources for Beginners

For newcomers to malware analysis, Jacob suggests several tools and resources, including Lenny Zeltser’s website and presentation. Zeltser is an authority in malware analysis, and his resources are an excellent starting point for those looking to deepen their understanding of malware and how to analyze it effectively.
