It is now the officially supported way to inject arbitrary nodes and edges into BloodHound. Any data source you can model as a graph — IoT inventories, SaaS permissions, custom infrastructure — can live alongside your Active Directory and Azure environments.</p> <p>I immediately wanted to use it during a pentest to visualise relationships between assets that BloodHound does not natively collect. My first attempt was hand-crafting the JSON. That worked for two nodes and one edge. It stopped being fun around the fifteenth node, when I mixed up <code>displayname</code> and <code>name</code> for the third time and the upload silently dropped half my data.</p>
