nisargsuthar / SigHunter

A C# (.NET 6) tool to compare the file signature of files recursively and inform the user of matches and mismatches

SigHunter

A DFIR-focused tool to help identify files masquerading as a different file type!

Sample Command

SigHunter.exe -d C:\temp\Path\To\Scan\Recursively -o C:\temp\Output\Folder

Output

Using the FileSignatures.cs dictionary of file extensions and their corresponding expected file signatures, SigHunter will output three CSV files:

• matched_files.csv - files that match the file extension with the expected file signature
• mismatched_files.csv - files that DO NOT match the file extension with the expected file signature
• unmatched_files.csv - files that do not have a file extension entry in the tool's dictionary

Feedback

There are a lot of improvements I want to make to this tool, but for now, it's functional and fast! Please report any issues here and I'll work on them as I have time!
