YARALYZER
YARALYZER is a command-line tool designed for visual inspection of regex and YARA matches within binary data and text files. The tool displays matched bytes in both hexadecimal and raw Python string representation, along with configurable context bytes before and after each match. The tool supports multiple scanning modes including YARA rule files, arbitrary regular expressions, and YARA hex patterns. Users can scan files against existing YARA definitions, custom regex patterns, or hex patterns without requiring a separate YARA file. YARALYZER provides colored output to enhance readability and allows analysts to examine what happens when different character encodings are applied to matched byte sequences. The tool eliminates the need to manually copy match positions into hex editors by directly displaying the relevant byte content. Installation is available through pipx, and the tool accepts various input formats including PDF files, executables, and binary data. The interface supports pattern matching for malware analysis workflows and binary inspection tasks.
