XRefer, an IDA Pro plugin, enhances binary analysis with a persistent companion view by employing Gemini-powered cluster analysis to decompose binaries into functional units, providing high-level architectural overviews akin to viewing a city’s districts.
Simultaneously, it offers a context-aware view that dynamically updates based on the analyst’s code location, which presents relevant artifacts from both the current function and related functions along the execution path, enabling efficient navigation and identification of critical code segments.
It is a binary analysis tool that can automatically decompose a binary program into functional units (clusters) using static analysis, where each cluster is labelled with a descriptive name to show its functionality.
By leveraging a large language model (LLM) named Gemini, it provides natural language descriptions of each cluster and how they relate to each other.

Users can navigate between clusters in a linear or graphical way to see the details of each cluster, including its member functions and their cross-references.
It offers two approaches for clustering: including all analyzed paths or focusing on a subset filtered by artifacts (functionalities extracted from the binary) with the help of LLM.
While the first approach is comprehensive, it may include irrelevant library clusters, and the second approach can be inconsistent due to the nature of LLMs but provides a cleaner view by filtering out noisy functions.
A plugin for the IDA Pro disassembler enhances code analysis by providing context-aware navigation, which classifies functions based on their relationships (clusters) and prefixes their names for easier identification.
A key feature is the function context table, which displays cluster membership, directly referenced artifacts (APIs, strings, etc.), and indirectly referenced artifacts reachable through execution paths.
Peek View allows analysts to filter artifacts based on a selected function’s execution path, offering a glimpse of downstream functionality, which allows generating path graphs that visually represent all execution paths leading to a specific artifact.
It is an IDA plugin that enhances binary analysis by providing cross-reference views, trace navigation, and artifact exclusion, which supports various artifact types, including function calls, strings, and API references.
By leveraging a Large Language Model (LLM), it analyzes relationships between artifacts and generates semantic descriptions for code clusters, which achieves this by building execution paths between entry points and functions containing artifacts.
It also supports language-specific analysis through modules, with a built-in Rust module for identification of library usage and basic function renaming.
According to Mandiant, XRefer’s initial release focuses on systematic code analysis, prioritizing accuracy over LLM-based summarization, which currently supports cluster analysis of code, providing high-level insights for analysts.
Future development includes extending cluster analysis to encompass code submissions, researching path-independent clustering for speed improvements, implementing LLM-based cluster merging, ensuring support for non-Windows file formats, and adding support for Golang modules.
