Identifying Parser Functions in Binary Executables with WebParserHunter

We present WebParserHunter, an interactive web application for automatically identifying parsing and validation functions in x86-32 and x86-64 binary executables without source code. This demo is the companion of the ParserHunter methodology [4] that relies on the SAFE embedding model and Graph Sage GNNs for code classification: analysts can upload any binary executable to the application and receive a ranked list with predicted probabilities of it being a parser, along with CFG visualizations and inline assembly. They can then launch an angr-based symbolic execution or a fuzzing campaign for deeper auditing within the same browser session.
