The malware may also be debugged while running using a debugger such as GDB or WinDbg to watch the behavior and effects on the host system of the malware step by step while its instructions are being processed. This form of analysis is often performed in a sandbox environment to prevent the malware from actually infecting production systems many such sandboxes are virtual systems that can easily be rolled back to a clean state after the analysis is complete. Some modern malware is authored using evasive techniques to defeat this type of analysis, for example by embedding syntactic code errors that will confuse disassemblers but that will still function during actual execution.ĭynamic malware analysis: Dynamic or Behavioral analysis is performed by observing the behavior of the malware while it is actually running on a host system. The machine code can sometimes be translated into assembly code which can be read and understood by humans: the malware analyst can then make sense of the assembly instructions and have an image of what the program is supposed to perform. The binary file can also be disassembled (or reverse engineered) using a disassembler such as IDA. Static malware analysis: Static or Code Analysis is usually performed by dissecting the different resources of the binary file without executing it and studying each component. The method by which malware analysis is performed typically falls under one of two types: Malware Analysis: To Examine Malicious Software Functionality.
