A harmful executable file is known as malware. Malware analysis is the study or process of identifying a particular malware sample’s behavior, source, and potential effect and gathering as much data as possible. Understanding the usefulness and extent of malware, how the system became infected, and how to protect against similar assaults in the future are all made possible thanks to the extracted information.

What is Malware Analysis?

The analysis, discovery, and mitigation of possible threats are all aided by a powerful Malware analysis practice. Organizations can spot malicious items used in sophisticated, focused, and zero-day assaults with Malware analysis. It is a significant procedure in defense. Security experts may analyze a suspicious file to determine whether it is safe to open or harmful. Responders need this information because it lowers false alarms and enables them to gauge the scope of a malware outbreak.

It is beneficial for both pre-incident preparation and response. Malware research, during an event, identifies and categorizes the malware and provides you with information to use. You can learn a wealth of information that aids in preventing subsequent occurrences by finding and recording the malware through Malware analysis.

What are the benefits of Malware Analysis?

Security analysts and crisis responders can significantly benefit from Malware analysis. Here are some of the procedure’s main advantages:

  • Determining the attack’s origin
  • Estimating the harm caused by a security danger
  • Determining the attack degree, weakness, and necessary patching measures for a piece of adware
  • Practically, events prioritized according to the seriousness of the danger
  • Identifying and blocking obscure Indicators of Compromise (IOC)
  • Increasing the effectiveness of messages, warnings, and IOC
  • Adding information when attempting to identify dangers


Types of Malware Analysis

  • Static Malware Analysis

While dynamic analysis takes features based on the execution of code, static analysis depends on elements that extract beforehand. (or emulation). Static analysis is typically more illuminating and practical than dynamic analysis, especially when dealing with highly obfuscated code. Without actually launching the malicious program, it is gathering information about it.

  • Dynamic Malware Analysis

A sandbox is a secure setting where suspected malicious code executes in dynamic Malware analysis. Security professionals can carefully monitor the malware in this closed, segregated virtual computer without worrying about infecting the machine or the network. This method makes the threat and its natural character more visible. It can be difficult, particularly when up against cunning foes who are aware that they use sandboxes ultimately.

  • Hybrid Malware Analysis

Hybrid Analysis is a file analysis technique that combines runtime data with memory dump analysis to uncover every potential virus operation route. The Hybrid Analysis engine instantly processes and incorporates all data from it into the reports on Malware analysis.


Key Steps of Malware Analysis

  • Configure your Virtual Computer

Virtual machines are an effective method to study malware because they can give it an isolated environment to trigger. Still, their activities can be monitored and stopped.

  • Examine Inactive Elements

Examining Inactive Elements is essential because malware may be able to take advantage of a weakness in the virtualization program, flee from the virtual setting, and infiltrate your host system.

  • Track Infectious Activity

Malware can infiltrate your computer using well-known program flaws. A weakness is similar to a gap in your software that allows viruses to enter your computer. When you visit a website, it might use marks in your web browser to install adware on your computer.

  • Decipher the Cypher

Decryption has benefits such as allowing entry to and understanding confidential data, safeguarding against data loss, and ensuring privacy and security. Decrypted data is compared to the original data to ensure it hasn’t been tampered with, which enables the authentication of data security.

  • Report any Virus

It aids emergency personnel in determining the scope of a malware-related event and locating additional possibly impacted hosts or systems. A company can mitigate weaknesses abused by malware more effectively and help avoid further compromise by using actionable information from malware research.


Stages of Malware Analysis

  • Static Properties Analysis

Strings encoded in malicious code, header information, hashes, metadata, embedded resources, etc., are examples of static characteristics. There is no need to execute the program to view this sort of data, making it possible that it is all required to generate IOCs. A deeper examination using more thorough methods may be necessary, and the next course of action is determined based on the knowledge gained during the static properties study.

  • Interactive Behavior Analysis

A lab-running malware sample can be observed and interacted with using interactive behavioral analysis. The model analysts examine the file system, registry, processes, and network behaviors to comprehend them. Memory forensics is a field of research that examines how software utilizes memory. Then, it looks at the malware’s potential abilities in a mock setting. Because behavioral analysis can be time-consuming and complex, it needs an analyst with advanced skills. With the assistance of automated instruments, the research was successful.

  • Fully Automated Analysis

Fully automatic Malware analysis merely evaluates suspicious files to ascertain the potential consequences of an infection of the network. It also generates an understandable summary that will give security teams prompt responses. It is a fantastic method to carry out malware research in bulk.

  • Manual Code Reversing

By reversing the malicious file’s code, comprehending the code’s reasoning, and discovering the file’s lost capability during behavioral analysis, someone can unlock the protected data held by the sample can be opened. Malware analysis tools like debuggers and disassemblers are needed to reverse the code. The skills necessary for physically decoding the code are difficult to come by but are vital.
