Factual Rules Generator
Factual Rules Generator is an open source tool that automatically generates YARA rules based on installed software detected on running operating systems. The tool analyzes software installations and creates detection rules that can be applied to digital forensic evidence to efficiently identify similar software installations across different systems. It focuses on baselining known software from Windows systems and generating rules for identifying comparable installations on other systems during forensic investigations. The tool requires several dependencies including pefile for PE file analysis, psutil for system information gathering, ndjson for data handling, python-tlsh for fuzzy hashing, PyInstaller for packaging, and ssdeep for similarity detection. Additional utilities like xxd and curl are also utilized in the rule generation process. The generated YARA rules can be integrated into forensic workflows to automate software identification and reduce manual analysis time during digital investigations.
