Liffy is a comprehensive Local File Inclusion (LFI) exploitation tool designed for security testing and penetration testing. It provides a modular command-line interface that supports multiple LFI techniques including data://, expect://, input://, filter:// wrappers, log poisoning, null byte attacks, ZIP wrapper exploitation, and blind LFI detection. The tool features advanced capabilities such as WAF bypass techniques, encoding layers, multi-threading with rate limiting, custom headers, POST request support, and rich terminal output. Architecture follows a modular design with core techniques isolated in separate modules, coordinated by a main orchestrator (liffy.py) that handles argument parsing, configuration loading, and execution management.
