HoundBench Cypher Queries Dataset

Dataset Description

This dataset contains 180 curated Cypher queries specifically designed for BloodHound, the popular Active Directory reconnaissance tool. Each entry pairs a natural language description with its corresponding Cypher query, train and eval your agents for BloodHound query generation :D.

Dataset Summary

• Total Examples: 180 query-description pairs
• Language: English (descriptions), Cypher (queries)
• Domain: Cybersecurity, Active Directory analysis, Graph databases
• Use Cases: Query generation, cybersecurity education, BloodHound automation

Supported Tasks

• Text-to-Code Generation: Generate Cypher queries from natural language descriptions
• Query Understanding: Understand the intent behind cybersecurity queries
• Educational Resource: Learn BloodHound query patterns and techniques

Dataset Structure

Data Instances

Each example contains:

{
  "description": "Find all users with an SPN (Kerberoastable users)",
  "query": "MATCH (n:User) WHERE n.hasspn=true RETURN n",
  "source": "https://hausec.com/2019/09/09/bloodhound-cypher-cheatsheet/"
}

Data Fields

• description (string): Natural language description of what the query accomplishes
• query (string): The corresponding Cypher query for BloodHound/Neo4j
• source (string): Attribution to the original source (URL, author, or publication)

Data Splits

The dataset is provided as a single collection. Users can create custom splits using the provided utilities:

from datasets import load_dataset
from utils.dataset_utils import split_dataset

dataset = load_dataset("joshtmerrill/HoundBench")
train_set, test_set = split_dataset(dataset, train_ratio=0.8)

Dataset Curators

This dataset was curated as part of the HoundBench project, a comprehensive toolkit for evaluating and validating Cypher queries against BloodHound instances.

Queries were curated from open and closed sources.

Usage Examples

Loading the Dataset

from datasets import load_dataset

# Load the full dataset
dataset = load_dataset("joshtmerrill/bloodhound-cypher-queries")

# Load with custom split
train_dataset = load_dataset("joshtmerrill/bloodhound-cypher-queries", split="train[:80%]")
test_dataset = load_dataset("joshtmerrill/bloodhound-cypher-queries", split="train[80%:]")

Basic Usage

# Iterate through examples
for example in dataset:
    print(f"Description: {example['description']}")
    print(f"Query: {example['query']}")
    print(f"Source: {example['source']}")
    print("---")

Integration with HoundBench

from utils.dataset_utils import load_queries_dataset, split_dataset

# Load using HoundBench utilities
dataset = load_queries_dataset("joshtmerrill/bloodhound-cypher-queries")

# Create train/test split
train_set, test_set = split_dataset(dataset, train_ratio=0.8, random_seed=42)

# Filter by source
hausec_queries = filter_dataset_by_source(dataset, ["hausec.com"])

Query Generation Example

from transformers import pipeline

# Load a text generation model
generator = pipeline("text-generation", model="your-model")

# Generate query from description
description = "Find all Domain Admins with active sessions"
prompt = f"Description: {description}\nQuery:"
result = generator(prompt, max_length=100)
print(result[0]['generated_text'])
