A python library to create BloodHound OpenGraphs easily


This library also exists in: Go | Python

Features

This module provides Python classes for creating and managing graph structures that are compatible with BloodHound OpenGraph. The classes follow the BloodHound OpenGraph schema and best practices.

If you don't know about BloodHound OpenGraph yet, a great introduction can be found here: https://bloodhound.specterops.io/opengraph/best-practices

The complete documentation of this library can be found here: https://bhopengraph.readthedocs.io/en/latest/

Examples

Here is an example of a Python program using the bhopengraph python library to model the Minimal Working JSON from the OpenGraph Schema documentation:

from bhopengraph.OpenGraph import OpenGraph
from bhopengraph.Node import Node
from bhopengraph.Edge import Edge
from bhopengraph.Properties import Properties

# Create an OpenGraph instance
graph = OpenGraph(source_kind="Base")

# Create nodes
bob_node = Node(
    id="123",
    kinds=["Person", "Base"],
    properties=Properties(
        displayname="bob",
        property="a",
        objectid="123",
        name="BOB"
    )
)

alice_node = Node(
    id="234",
    kinds=["Person", "Base"],
    properties=Properties(
        displayname="alice",
        property="b",
        objectid="234",
        name="ALICE"
    )
)

# Add nodes to graph
graph.add_node(bob_node)
graph.add_node(alice_node)

# Create edge: Bob knows Alice
knows_edge = Edge(
    start_node=alice_node.id,
    end_node=bob_node.id,
    kind="Knows"
)

# Add edge to graph
graph.add_edge(knows_edge)

# Export to file
graph.export_to_file("minimal_example.json")

This gives us the following Minimal Working JSON as per the documentation:

{
  "graph": {
    "nodes": [
      {
        "id": "123",
        "kinds": [
          "Person",
          "Base"
        ],
        "properties": {
          "displayname": "bob",
          "property": "a",
          "objectid": "123",
          "name": "BOB"
        }
      },
      {
        "id": "234",
        "kinds": [
          "Person",
          "Base"
        ],
        "properties": {
          "displayname": "alice",
          "property": "b",
          "objectid": "234",
          "name": "ALICE"
        }
      }
    ],
    "edges": [
      {
        "kind": "Knows",
        "start": {
          "value": "123",
          "match_by": "id"
        },
        "end": {
          "value": "234",
          "match_by": "id"
        }
      }
    ]
  },
  "metadata": {
    "source_kind": "Base"
  }
}
