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.
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:
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 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.
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.
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.
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.
The following points explain the use of Malware Analysis:
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.
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.
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.
Following are some importance of malware analysis.
