Malware Analysis:

Definition, Types, and Stages

What Is Malware Analysis?

Malware analysis is a technical process used to deeply examine and understand malware. The goal of this technique is to understand how it works, its impact on a system, and how to detect and mitigate it.

By conducting this analysis, you can identify attack patterns and characteristics of dangerous malware before it infects a system. Understanding this analysis helps develop effective defense strategies and appropriate mitigation measures when a security incident occurs.

Benefits of Malware Analysis

Before implementing it, let’s understand why you need to conduct malware analysis to maintain digital security.

Understanding Attack Patterns and the Latest Malware Techniques

By conducting malware analysis, you can identify new techniques and patterns in malware used by attackers. This is crucial for developing a security system that stays up-to-date.

Helps Develop Malware Detection and Prevention Systems

Information gained from malware analysis can be used as a basis for developing more sophisticated detection technologies, such as antivirus and firewalls. This way, they can prevent malware attacks before they damage a system.

The Foundation for Effective Cybersecurity Incident Management

Proper malware analysis will help expedite the security team’s response to an incident. It will also minimize the impact of damage and expedite the recovery process.

Supporting Digital Forensic Investigations

In cybersecurity cases, the malware analysis process will help gather valid digital evidence. This data can then be used in legal proceedings or further investigations.

Types of Malware Analysis

There are two types of malware analysis that can be applied: static and dynamic analysis. See a brief explanation below!

1. Static Analysis

This analysis is performed without running the malware. A malware analyst will examine the code, metadata, and file structure of the malware. With this technique, they can determine the characteristics of the malware without infecting critical systems.

2. Dynamic Analysis

Unlike static analysis, this technique is performed by running the malware in an isolated environment—such as a sandbox or virtual machine. Dynamic analysis is performed to observe the behavior of the malware in real time—even while it is active.

To make it easier for you to compare the two, here’s a simple table outlining the differences between static and dynamic analysis:

Differences Between Static and Dynamic Analysis Static Analysis Dynamic Analysis

Malware Execution Does not execute malware Executes malware in a secure environment

Analysis Focus: Code, metadata, file structure Malware behavior and effects

Infection Risk: Low Risk if environment is unsecured

Processing Speed: Fast Slower due to real-time observation

Information Obtained: Technical characteristics Malware impact and activity

Malware Analysis Stages

There are several steps you must follow. By following this process, you can produce an accurate and actionable malware analysis.

1. Malware Sample Collection

First, you must collect malware samples from various sources—such as infected systems, honeypots, or threat intelligence platforms. Also note the time the data was collected and the context in which it was distributed. Afterward, store the files in an isolated environment to prevent their spread.

2. Initial Static Analysis

Following this, perform a static analysis to quickly identify the malware. This analysis includes hash checks, file types, antivirus signatures, and hidden string checks. The results of this step can provide initial clues before proceeding to the deeper dynamic analysis stage.

3. Dynamic Analysis

Next, you can run the malware in a controlled environment—such as a sandbox or virtual machine. This allows you to directly observe what the malware does—such as file changes, network activity, and even system registry manipulation. This way, you can understand the malware’s potential impact on your system.

4. Reporting Results

After all processes are complete, you need to create an analysis report containing a description of the malware, infection techniques, affected data, and mitigation recommendations that your IT team can implement.

Preparing a good report will aid in the mitigation process, documentation, and long-term security system improvement.

Tools Used in Malware Analysis

To perform malware analysis, you need various tools to assist in this process. Each tool is designed for a specific purpose, so you need to choose the right one.

Static Analysis Tools

Disassembler (IDA Pro, Ghidra): This tool is used to disassemble executable files and read the assembly instructions within them. Typically, this tool is used to manually analyze malware logic.

Hex Editor: This tool can open the internal structure of a file and view raw data, hidden strings, and even specific signatures in hex format.

Antivirus Signature Scanner: Finally, this tool helps compare your file against a database of known malware signatures to detect threats more quickly.

Dynamic Analysis Tools

Sandbox (Cuckoo, Any.Run): Sandboxes are used to run malware in a virtual environment so you can observe its behavior without increasing the risk of its spread.

Debugger (x64dbg, OllyDbg): These tools help you trace each program instruction as it executes to see what the malware is actually doing.

Wireshark: Wireshark is a network packet analyzer that is very effective for observing malware communication activity—including where it sends data.

Process Monitor (Procmon): This tool from Sysinternals can monitor changes to system files, the registry, and processes modified by malware.
