SimAI Binary Code Homology Search

The semantic-based binary code homology search capability supports the retrieval of potential open-source component functions in unknown binary codes and provides applicable fine-grained result details.

Symbol and Type Recovery

Based on the expert LLM' reasoning, semantic symbols such as function names, variable names, source code-level variable type and structure definition recovery is supported.

Semantic Analysis and Code Documentation

Automated binary code semantic analysis performs context-based function behavior reasoning, aiding code understanding with function documentation and inline comments.

Results Review and Application

It supports manual review of predicted results by LLMs, allowing modification or selective application of the results; the predicted symbol information and types (including structure types) can be applied to binary code and propagated automatically.

More Features

Decompilation Augmentation

Automatically Analyzes and Improves the readability of decompiled code.

Functionality Recognition

Identify function categories and algorithm classes.

Structure Recovery

Automatically analyze the memory structure of complex type variables and restore the structure.

General Model

General model can be used to power ReCopilot.

Our Vision

ReCopilot aims to revolutionize binary analysis practices by combining the power of Large Language Models (LLMs) with expertise in reverse engineering. We are dedicated to providing reverse engineers with an intelligent and efficient tool to help them understand complex binary programs faster and more deeply.

Limitations and Risks Associated with Using This Project

Currently, ReCopilot is a research-based experimental project, and we are not responsible for the model's capabilities unrelated to political biases, harmlessness, etc. This model is designed for specific binary reverse engineering tasks, not for dialogue. Therefore, we do not actively provide conversational model interaction interfaces, and we do not recommend accessing the model's dialogue capabilities via API. Please understand the limitations and risks of using this project.
