This repository is a comprehensive database of binary file format patterns, YARA rules, encoding tables, themes, and utility scripts for the ImHex hex editor. It contains over 300 ImHex pattern definitions (`.hexpat`) covering a vast range of file formats including executables, archives, multimedia, game assets, filesystems, and firmware. The patterns are written in ImHex's custom pattern language and are organized with a reusable standard library (`includes/std/`, `includes/type/`) and ImHex-specific helpers (`includes/hex/`). The repository also includes a large collection of YARA rules from the official YARA-Rules community, covering malware families, APT groups, exploit kits, and CVEs. Additional assets include encoding tables (`.tbl`), magic files for libmagic, disassembler definitions, themes, and data processor nodes. The project is primarily a data/research resource for reverse engineers, malware analysts, and digital forensics practitioners, but it also includes application-like elements such as Python scripts for format conversion and encoding generation, as well as a CMake-based test suite for validating patterns and includes. The repository is actively maintained with community contributions and CI testing.
