Look for networking ( ws2_32.dll ) or file manipulation ( Kernel32.dll ) functions that hint at the program's behavior. 3. Decompilation & Logic Flow
Identify the entry point and the primary loop. Key Logic: Does it ask for a password? Does it perform a mathematical transformation (XOR, ROT13)? ex02b.exe
Briefly explain the "lesson" of the challenge (e.g., "This taught the basics of string obfuscation"). To give you a more detailed draft, could you tell me: Is this for a specific course or CTF ? What behavior do you see when you run it? Look for networking ( ws2_32
[e.g., Identify the hidden flag / Understand the encryption logic] Tools Used: Detect It Easy (File identification) Ghidra or IDA Free (Static analysis) x64dbg (Dynamic debugging) 2. Static Analysis Key Logic: Does it ask for a password
Describe what happens when you run it (e.g., "The console prints 'Access Denied' immediately"). Debugger Findings:
A professional write-up should be structured to show the file is, how it works, and what the final result is. 1. Executive Summary File Name: ex02b.exe File Type: Windows Executable (PE)
Check the MD5/SHA256 hashes to ensure file integrity.
