How to start in Malware Analysis

Malware analysis is a fascinating field that sits at the intersection of incident response, forensics, system administration, security monitoring, and software engineering. If you have a passion for cybersecurity and want to dive deeper into the world of malware, becoming a malware analyst may be the perfect career path for you. In this comprehensive guide, we will provide you with all the information you need to get started in the field of malware analysis.

Understanding the Malware Analysis Process

Before diving into the specifics of malware analysis, it's important to understand the different stages involved in the process. Malware analysis can be broken down into four main categories, each requiring a different set of skills and techniques:

Fully-Automated Analysis: This involves running suspicious files in an automated analysis environment, also known as a "sandbox," to gather information about their activities. It provides a high-level overview of the malware's behavior without the need for manual intervention.

Static Properties Analysis: This step involves examining metadata and other details embedded in the file, such as strings, without actually running it. By analyzing these static properties, you can identify areas that may require further investigation in subsequent analysis steps.

Interactive Behavior Analysis: In this stage, the malware is executed in an isolated laboratory environment that you fully control. By tweaking the lab's configuration in a series of iterative experiments, you can study the malware's behavior and understand its capabilities.

Manual Code Reversing: This is the most challenging and time-consuming part of the analysis process. It involves examining the code that makes up the malware using tools like disassemblers and debuggers. By dissecting the code, you can gain a deep understanding of the malware's inner workings.

Memory, file system, and network forensics efforts also contribute to the overall understanding of the malware.

Assessing Your Skills and Getting Started

Now that you have a basic understanding of the malware analysis process, it's time to assess your existing skills and determine where you fit into this field. Take a moment to ask yourself, "What skills do I have today, and where do they fit into the malware analysis process?" This self-assessment will help you identify your strengths and areas for improvement.

If you're just starting out in malware analysis, it's essential to learn from experienced analysts and study their findings. By examining reports published by seasoned analysts and automated sandboxes, you can gain insights into the analysis techniques and methodologies employed. Make note of the aspects that make sense to you and identify areas that require further study.

There are various sources where you can find malware analysis reports, such as the LearnREM page on Facebook, which provides a curated list of websites and blogs that cover the latest industry insights. Additionally, several free malware analysis sandboxes are available, which allow you to access reports on analyzed malware samples. By reviewing these reports, you can learn about the flagged behaviors that indicate malicious activity and identify Indicators of Compromise (IOCs).

To gain hands-on experience, it's crucial to set up a lab environment where you can experiment with malware in an isolated and controlled setting. Virtualization software like VMware Workstation Pro or VirtualBox allows you to create virtual machines (VMs) and install different operating systems to facilitate your analysis. By following tutorials and guides, you can learn how to set up and configure your lab environment effectively.

Learning Resources for Malware Analysis

To further enhance your skills in malware analysis, it's essential to leverage learning resources and study materials specifically tailored for this field. Here are some highly recommended resources that cover various aspects of malware analysis:
