XRefer is a Python-based plugin for the IDA Pro disassembler, a tool used for analyzing software. The plugin provides a custom navigation interface within IDA. It examines execution paths from entry points, breaks down the binary into clusters of related functions, and highlights downstream behaviors and artifacts for quicker insights. XRefer can incorporate external data (e.g., API traces, capa results, user-defined xrefs) and provides path graphs for richer context. It integrates with Google's Gemini model to produce natural language descriptions of code relationships and behaviors. Additionally, XRefer can provide cluster based labels for functions, aiming to accelerate the manual static analysis process.
