What is Malware Analysis?

Malware Analysis Malware Analysis refers to the process which helps in determining the purpose and functionality of a given malware. A malware is a malicious program and it has many variants such as viruses, worms, or Trojan horse. To develop powerful detection techniques for malware, the malware analysis plays a significant role in the process.

Static Malware Analysis

On the other hand, it is an important phase for creating malware removal tools which can effectively respond to remove the infection from the system. Ten years ago, malware analysis was carried out manually by technical experts, and the entire process was laborious and time-consuming. Since the number of malware attacks kept increasing drastically, it demanded for effective malware analysis tactics.

Different types of malware analysis?

  1. Static Malware Analysis
  2. Dynamic Malware Analysis

The static analysis detects malicious program without really running it. Dynamic analysis sometimes also referred to as the behavior analysis runs the malware in a containment to observe its behavior. Both the techniques incorporate elements which can be categorized as basic or advanced. An analyst would be able to cull out more details about the malicious programs by conducting static and dynamic analysis as separate tasks.

This can help in providing a series of technical indicators which may not be obtainable by basic static analysis alone. This article here discusses the key techniques of both analysis:

Static Analysis

The static analysis checks for malware without inspecting the actual code or instructions. It applies various techniques and tools to swiftly decide whether the file is malicious or not. It also provides insights into the malware functionality and assembles technical indicators to create simple signatures. The indicators collected using static analysis may comprise the file name, file type, file size, and MD5 checksums or hashes recognized by antivirus detection tools.

Dynamic Analysis

The dynamic analysis basically runs malware to examine its behavior, gain insights into its functionality and recognize technical indicators which can be used in detection signatures. The technical indicators shared with dynamic analysis would tech the domain names, IP addresses, registry keys, file path locations, extra files found on the system or network.

Besides that, it will reveal the connection with the hacker-controlled external server for command and control purposes. It is very similar to what most automated sandboxes or dynamic malware analysis engines do today. The traditional methods have been successfully replaced with automated analysis through open-source projects or custom homegrown solutions and commercial sandboxes for various time and resource reasons.

Threat Analysis

The threat analysis is a continuous process which aids in detecting patterns of malicious software. With adversaries frequently replacing network infrastructure, it is obvious to lose sight of the tools constantly being used and updated by these various actors. Beginning with malware family analysis, these tests continue to mapping vulnerabilities, exploits, additional malware, network infrastructure, and adversaries.

Comodo Valkyrie

Comodo Valkyrie is a powerful file verdict system. In comparison to the traditional signature-based malware detection techniques, the Comodo Valkyrie conducts various investigations using run-time behavior and hundreds of features from a file. It is quick enough to detect zero-day threats missed by the signature-based detection systems of traditional antivirus products.
