Sekiryu v0.0.2: Automating Ghidra for Advanced Binary Analysis

Sekiryu v0.0.2: Automating Ghidra for Advanced Binary Analysis

Sekiryu v0.0.2 is a powerful toolkit designed to enhance and automate the use of Ghidra, a popular reverse engineering tool, in Headless mode.

This toolkit provides a suite of scripts and features that streamline binary analysis tasks, from vulnerability hunting to pseudo-code generation and reporting. Below is a detailed guide on its features, installation, usage, and customization.

Key Features

1. Headless Mode Automation

Sekiryu enables seamless execution of Ghidra in Headless mode, allowing users to automate and batch-process code analysis tasks without requiring the graphical interface.

2. Script Repository and Management

  • Includes a repository of pre-built scripts for various functionalities like vulnerability detection, pseudo-code generation, and reporting.

  • Users can load, save, and organize custom scripts tailored to specific analysis needs.

3. Flexible Input Options

Analyze individual files or entire folders containing multiple binaries, making it suitable for both small-scale and large-scale codebases.

4. Available Scripts

  • Vulnerability Hunting with Pattern Recognition: Identify potential vulnerabilities in the analyzed codebase using built-in scripts.

  • Vulnerability Hunting with SemGrep: Leverage SemGrep rules (created by 0xdea) to detect vulnerabilities in C/C++ pseudo-code.

  • Automatic Pseudo-Code Generation: Generate pseudo-code automatically within Ghidra's Headless mode to simplify understanding of binary logic.

  • Pseudo-Code Commenting with ChatGPT: Use ChatGPT to add human-readable comments to pseudo-code snippets for better documentation.

  • Reporting and Data Visualization: Create detailed reports with visualizations to summarize analysis results effectively.

Pre-Requisites

Before using Sekiryu, ensure the following software is installed:

  1. Ghidra: Download from the NSA's GitHub repository.

  2. Java Development Kit (JDK) 17 or higher: Obtain from the OpenJDK website.

  3. Optional:

    • BinExport: Install as a Ghidra extension for enhanced export capabilities.

    • SemGrep: Follow the SemGrep documentation for installation.

Installation

1.Install the required software listed above.

2.Download Sekiryu from its GitHub repository or install it via pip:

pip install sekiryu

Usage

Run Sekiryu against a binary file or folder with desired options:

sekiryu [-F FILE] [OPTIONS]

Note: Binary analysis can be time-intensive depending on system performance and file size.

Example Workflow

  1. Use Sekiryu to analyze a binary file in Headless mode.

  2. Apply scripts for vulnerability detection or pseudo-code generation.

  3. Generate reports for further insights.

Customization

Sekiryu supports user-created scripts that interact with Ghidra's API via XML-RPC. Here's how you can create and integrate your own script:

1. Save Custom Scripts

Save your script in the /modules/scripts/ folder.

2. Modify ghidra_pilot.py

Add a function to execute your script:

def yourfunction(file):

    try:

        script = "modules/scripts/your_script.py"

        thread = threading.Thread(target=exec_headless, args=(file, script))

        thread.start()

        thread.join()

    except Exception as e:

        print(str(e))

3. Command-Line Interface (CLI)

Update cli.py to include custom commands:

analysis_parser.add_argument('[-ShortCMD]', '[--LongCMD]', help="Your Help Message", action="store_true")

API Functions

The server.py module allows scripts to interact with Ghidra and the host system through these functions:

  • send_data(data): Send a dictionary of data to the server.

  • recv_data(): Receive data as a dictionary from the server.

  • request_GPT(string): Send string data via ChatGPT API for processing.

Contributions

Sekiryu is open-source and welcomes contributions in areas like:

  • New scripts for automation or malware analysis.

  • Optimizations for better performance (e.g., parallel processing).

  • Enhanced reporting and data visualization tools.

Warnings

The xmlrpc.server module used by Sekiryu is not secure against maliciously constructed data. Avoid using it with untrusted or unauthenticated inputs.
