Binwalk
Binwalk is a firmware analysis tool and binary data carver used to identify and extract embedded files and data segments from binary images. It functions as an embedded file extractor and data entropy analyzer to retrieve fragments from binary blobs when original file system structures are missing.
The tool employs signature-based pattern matching and linear byte-stream scanning to detect known byte sequences and isolate hidden files. It uses sliding-window entropy analysis to locate regions of a file that are compressed or encrypted.
The system supports recursive file carving, utilizing heuristic-based boundary detection and offset-based data extraction to slice nested content into standalone files.
