In this blog, we will discuss Malware Analysis.

Malware Analysis:-

The unmarried period used for malicious software programs is malware. The malicious applications designed by using cybercriminals can be together referred to as malware. The malicious programs gain get entry to computing devices using creating a backdoor entry to steal personal information, confidential facts, and many others. Analysis of malware ought to be carried out to recognize the sorts of malware, nature of malware, and the attacking methodologies of malware, as malware attacks are increasing day by day. The process of analyzing and determining the reason and capability of the malware is called malware analysis. The facts obtained using malware evaluation can be used to develop techniques of detection for malware.

Conduct Malware Analysis:-

It is used to deal with the intrusion of the network by providing the necessary information. Determining what happened exactly and locating the files and machines that are infected by malware is the main goal. When we are analyzing the infected machines or files, our goals must be:

  • To understand what the suspected malware is capable of.
  • How to detect the malware in the network.
  • Determine how to measure and manage the damage it is going to cause.
  • After identifying the files that are infected, signatures must be developed to detect malware infections on the network.
  • Signatures that are host-based or indicators are used to detect malware on the computers.
  • The indicators of malware determine the effect of malware on the system.
  • Network signatures or indicators are used to detect malware by monitoring the traffic on the network.

Stages of Malware Analysis:-

There are four stages of malware analysis. The stages are in the form of a pyramid and as we go higher in the pyramid, the complexity of the analysis stage increases. The stages are:

  • Fully Automated Analysis

Fully automated tools must be used to scan and assess a suspicious program. Fully automated tools are capable of understanding what the malware infecting the network is capable of. A report in detail is generated by the fully automated tools about the traffic in the network, file activity, and registry keys. Analyst provides more information when compared to fully automated analysis, but it is the fastest method to scan the malware in large quantities.

  • Static Properties Analysis

We must look at the static properties of malware to get a deeper look at malware. It is easy to access the static properties of malware because running the malware takes a longer time. Hashes, embedded strings, header information, etc. are the static properties of malware.

  • Interactive Behavior Analysis

The malware or the malicious file is put under observation by putting it in a separate laboratory and observing the effects of malware on the laboratory. The laboratory is under complete observation by the analysts to check if the malware is attaching any hosts. From the information obtained by this observation, the analyst will recreate the situation to understand what the malware does when it is connected to the host.

  • Manual Code Reversing

The encrypted data stored by the sample can be decoded by reversing the code of the malicious file, understanding the logic of the code, and the file capabilities that were not found during behavioral analysis. The malware analysis tools such as debuggers and disassemblers are required to reverse the code manually. It is hard to find the skills required for reversing the code manually, but they are very important.

Malware Analysis Use Cases

The following points explain the use of Malware Analysis:

  • Computer Security Incident Management

If an organization finds out that malware is infecting their systems, they have a response team to respond to the situation. As part of the response, all of the suspicious malware files identified will be put under malware analysis to determine if it is malware, if yes, what type of malware is it, and what is the effect of that malware on the systems in the organization.

  • Malware Research

The researchers of malware perform malware analysis in an academic or industry forum to understand better how the malware works and the methods used to create this malware.

  • Indicator of Compromise (IOC) Extraction

It is conducted in bulk by the software solutions and product sellers to determine new indicators of malware attacks. This helps organizations to protect themselves from malware attacks.

  • Importance

Following are some importance of malware analysis.

  1. For all sorts of analysis related to crimes in the organization, it is very much necessary. There is too much malware that can easily get into the information technology domain of an organization with the growth of malicious codes and files increasing day by day.
  2. Most of the malware is disguised to be beneficial programs to the enterprise even as the actual reason for them is to contaminate the structures within the organization. Firewall and anti-malware software programs may be used towards malware attacks but simply firewall and anti-malware software aren't sufficient to save you malware attacks and this is while malware analysis comes into the image. Extreme opposite engineering has to be carried out to apprehend the malware and simply blockading the firewall isn't always of much assist. The analyst must understand assembly language and have to realize what must be identified.
  3. The malware industry is there for a long time and it is a business with great profit. This is one of the attractive reasons to study malware. It is a combination of psychology, technology, and commerce and this makes malware analysis interesting.
  4. In keeping with the research, new malware is created every four.2 seconds. For all of the emerging malware, the malware analysts broaden defenses and the attackers must create new malware to overcome the defense created via the analysts to infect the machine. Even though the detection of malware and elimination abilities are enhancing each day, unfavorable software has been created each day. This explains the need for malware analysis.
