Malware analysis is the study or process of determining the functionality, origin and potential impact of a given malware sample such as a virus, worm, trojan horse, rootkit, or backdoor. [1] Malware or malicious software is any computer software intended to harm the host operating system or to steal sensitive data from users, organizations or ...
Research in combining static and dynamic malware analysis techniques is also currently being conducted in an effort to minimize the shortcomings of both. Studies by researchers such as Islam et al. [13] are working to integrate static and dynamic techniques in order to better analyze and classify malware and malware variants.
In computer science, static program analysis (also known as static analysis or static simulation) is the analysis of computer programs performed without executing them, in contrast with dynamic program analysis, which is performed on programs during their execution in the integrated environment. [1] [2]
Static analysis involves studying the software code of a potentially malicious program and producing a signature of that program. This information is then used to compare scanned files by an antivirus program. Because this approach is not useful for malware that has not yet been studied, antivirus software can use dynamic analysis to monitor ...
Static analysis can be done manually as a code review or auditing of the code for different purposes, including security, but it is time-consuming. [7] The precision of SAST tool is determined by its scope of analysis and the specific techniques used to identify vulnerabilities. Different levels of analysis include:
A software analysis and testing tool suite, that performs static analysis, standards enforcement (eg. MISRA C/C++), dynamic analysis, unit testing and requirements traceability. Lint: 1978-07-26 Yes; permissive BSD-like [10] — C — — — — — The original, from 1978, static code analyzer for C. MALPAS: No; proprietary Ada C — — — —
Dynamic analysis can use runtime knowledge of the program to increase the precision of the analysis, while also providing runtime protection, but it can only analyze a single execution of the problem and might degrade the program’s performance due to the runtime checks.
Heuristic analysis is a method employed by many computer antivirus programs designed to detect previously unknown computer viruses, as well as new variants of viruses already in the "wild". [ 1 ] Heuristic analysis is an expert based analysis that determines the susceptibility of a system towards particular threat/risk using various decision ...
