Malware Analysis & Cybersecurity

Malware is a type of invasive software that can harm and destroy computer networks, servers, hosts, and computer systems. It serves as a blanket word for any forms of malicious software that are created with the purpose of causing harm to or abusing any programmable system, network, or service. Malware threats emerge in a variety of forms, including viruses, worms, adware, spyware, trojan viruses, and ransomware.

Malware analysis is the process of identifying and minimizing possible dangers to a website, application, or server. It is an essential procedure that improves sensitive information protection as well as computer security for a company. Vulnerabilities are addressed through malware analysis before they become major problems.

How can Malware analysis assist security professionals in detecting and preventing security threats?

Performing Malware analysis helps security professionals in the following ways: -

  1. To determine the origin of cyber-attacks.
  2. To estimate the severity and impact of a potential security threat.
  3. To determine the exploitation potential, vulnerabilities, and patching mechanisms.
  4. To logically prioritize the malware activity based on the seriousness of the threats.
  5. To identify and block any hidden IoCs (Indicators of Compromise) and IoAs (Indicators of Attack)
  6. To improve the effectiveness of IoCs, IoAs, SOC alerts, and notifications.

Malware analysis methodologies preferred by Cyber Security professionals

Static Analysis

During a static malware analysis, the malware's source code is inspected. After decoding the malware's source code, the IT team can inspect it to determine how it operates. By observing how the code operates, IT personnel may be able to build more secure procedures. In addition, static malware analysis serves as a logic check for the final analysis of dynamic malware.

Dynamic Analysis

Dynamic malware investigation refers to the process of quickly analyzing how malware acts. This requires checking the system for any changes the virus may have done. Newly launched processes and those whose settings have recently changed are tracked. In addition, the analysis would consider any changes to the DNS server settings on the client workstation. In addition to analyzing files and processes, dynamic malware investigation also analyzes network traffic and system behavior.

Combinatorial Malware Analysis

The most advantageous method is to combine both kinds of malware analysis methods. Combinatorial malware analysis can extract many more IoCs from statically generated code and uncover buried malicious code. Even the most complex malware may be detected by it.

Application of Malware Analysis in cybersecurity

Application of YARA and Sigma rules to detect and hunt threats

More advanced methods are being used by adversaries to elude existing detection systems. Threats may be found more quickly by using YARA and Sigma rules to spot malicious functionality or suspicious infrastructure. Extraction of IoCs is another result of malware investigation. To help teams stay alert to relevant risks in the future, the IoCs may subsequently be fed into SIEM solutions, TIPs (Threat Intelligence Platforms), and security orchestration tools.

Research & Development in Detection Engineering

Malware researchers from academia or corporate industries analyze malware to learn about the most recent tactics, vulnerabilities, and tools employed by adversaries. Threat researchers can leverage behavior and artifacts revealed by malware analysis to identify comparable activities, such as access to a certain network connection, port, or domain. SOC teams may utilize this data to detect comparable threats by analyzing firewall and proxy logs or SIEM data. Early in the attack life cycle, malware analysis systems offer higher-fidelity alarms. Security teams can therefore save time by prioritizing the outcomes from these alerts over other technologies.
