Exam 312-49v10 topic 1 question 612 discussion

The correct answer is B. Ollydbg. Ollydbg is a debugger that can disassemble executable files, translating machine code into assembly language, allowing Harry to reverse engineer the executable and understand its behavior. Here's why the other options are not the best choices: A. HashCalc is a tool for calculating hash values, not for reverse engineering or disassembling executables. C. BinText is a tool for extracting text strings from binary files, but it's not a disassembler. D. oledump is a tool for analyzing OLE (Object Linking and Embedding) files, not for disassembling executables. Ollydbg is a popular choice for reverse engineering and debugging on Windows platforms.

OllyDbg is a 32-bit assembler level analyzing debugger for Microsoft Windows. Emphasis on binary code analysis makes it particularly useful in cases where source is unavailable. Once the suspected malware sample is loaded on OllyDbg, it will show assembler mnemonics, opcodes, and virtual addresses. Investigators can set breakpoints and run the code to see how the malware functions. It is also possible to modify the execution flow of a malware file with OllyDbg.
