Malware Analysis Proccess

• Static Analysis

  • Static Analysis can be done by checking physical states of file. In our case , we used executable file as static samples and to check the physical states of windows executable file Windows provide Portable Executable Format (PE Format) which describes the structure of executable (image) files and object files under the Windows family of operating systems. These files are referred to as Portable Executable (PE) files.

• Dynamic Analysis

  • Behaviour Analysis is similar to Dynamic Analysis therefore we created sandbox to find the behaviour of our malicious and good samples and these behaviour includes Registry Operations , Files Operations , Api's Calls , Dll loaded , Mutex Information etc

• Code Analysis

  • reversing code with debugger tools
  • Debugging and Reverse Engineering ,Disassemblers, decompiler

• Memory Analysis

  • we dumping whole memory and checking for process and handler.
  • we can find Rootkit and Ransomware Encryption key and find hidden process !
