Malware Analysis

Malware analysis is the process of examining malicious software, or malware, in order to understand how it works and what it is capable of doing. The goal of malware analysis is to identify the malware’s functionality, behavior, and potential impact on a system or network.

There are several different techniques that can be used for malware analysis, including:

Static analysis: This involves examining the malware’s code and other non-executing components without actually running the malware.
Dynamic analysis: This involves running the malware in a controlled environment and observing its behavior.
Behavioral analysis: This involves studying the malware’s behavior on a live system, such as the network traffic it generates or the files it modifies.
Reverse engineering: This involves disassembling the malware’s code to understand its inner workings and identify its components.
Memory analysis: This involves analyzing the malware’s memory usage to understand how it is interacting with the system.

The results of malware analysis can be used to identify vulnerabilities in a system, develop countermeasures to prevent the malware from executing or spreading, and develop strategies for responding to an infection.

Malware analysis is typically carried out by cybersecurity professionals such as malware analyst, incident responders, and forensic investigators to protect organizations against cyber threats.

The methodology for malware analysis typically includes the following steps:

Collection: This includes obtaining a sample of the malware, which can be done through a variety of means such as spear-phishing, honeypot, intrusion detection system alerts, or by purchasing it from a threat intelligence provider.
Initial Analysis: This includes performing initial triage on the malware sample to determine its type and potential impact. This can include checking file properties, running basic dynamic analysis, or checking the malware’s reputation in online databases.
Static Analysis: This includes analyzing the malware’s code and other non-executing components without actually running the malware. This can include disassembling the code, examining strings and resources, and identifying any known indicators of compromise.
Dynamic Analysis: This includes running the malware in a controlled environment and observing its behavior. This can include monitoring network traffic, file system changes, and system registry changes.
Behavioral Analysis: This includes studying the malware’s behavior on a live system, such as the network traffic it generates or the files it modifies. This can include using tools such as sandboxing, network sniffers, and process monitoring.
Reverse Engineering: This includes disassembling the malware’s code to understand its inner workings and identify its components. This can include using debuggers, decompilers, and other specialized tools.
Memory Analysis: This includes analyzing the malware’s memory usage to understand how it is interacting with the system. This can include using tools such as memory dumpers and memory forensics tools.
Reporting: This includes documenting the findings of the analysis, identifying any vulnerabilities or weaknesses in the malware, and making recommendations for preventing or mitigating the malware’s impact.

It’s important to note that the specific steps and tools used in malware analysis may vary depending on the type of malware and the goals of the analysis.

The deliverables of malware analysis typically include:

A report detailing the findings of the analysis, including the malware’s functionality, behavior, and potential impact on a system or network.
A detailed assessment of the malware’s code, including any known vulnerabilities or weaknesses.
A summary of the malware’s behavior, including any files it modifies, network traffic it generates, and system changes it makes.
Information about the malware’s command and control infrastructure, including IP addresses, domains and any other communication channels
Identification of any known indicators of compromise (IOCs) that can be used to detect and prevent the malware from executing or spreading.
Recommendations for preventing or mitigating the malware’s impact, including specific actions that shall be taken to remediate the threat.
A list of tools and techniques used during the analysis and a summary of the methodology used.

The benefits of malware analysis include:

Improved security: By understanding how malware works and what it is capable of doing, organizations can better protect their systems and networks from future attacks.
Increased visibility: Malware analysis provides insight into the behavior and impact of malware, which can help organizations to better understand the risks they face.
Identification of vulnerabilities: Malware analysis can help organizations identify vulnerabilities in their systems and networks that could be exploited by attackers.
Compliance: By identifying and mitigating malware, organizations can better comply with relevant security policies and regulations.
Incident response: Malware analysis can also be used to investigate a security incident, by understanding the nature and extent of the compromise, and to develop an incident response plan.
Peace of mind: Knowing that a potential threat has been thoroughly analyzed and mitigated can provide peace of mind for organizations and their stakeholders.
