ShareHound: Mapping rights of network shares using BloodHound OpenGraph

A tool to map the access rights of network shares into BloodHound OpenGraphs.

Two implementations

This repository contains two implementations of ShareHound. They share the same goal — producing BloodHound OpenGraph JSON from SMB share permissions — but differ in language, runtime, and feature set. Pick whichever fits your workflow.

Each subdirectory has its own README with full installation, usage, and configuration details:

• Python/README.md
• Go/README.md

Features (common to both)

• Map network shares of a domain and their rights in BloodHound OpenGraph format
• Highly customizable rule matching via the ShareQL language
• Multithreaded discovery of shares (Breadth First Search)
• NTLM, Kerberos, and pass-the-hash authentication
• CIDR range and target file support

Additional features in the Go implementation

• ZIP-compressed streaming output (handles millions of edges)
• Resumable scans via checkpoint files
• --effective-access-only mode to drastically reduce graph size on large environments
• Cross-platform static builds (Linux, Windows, macOS)

Quick start Cypher queries

Once you've imported the OpenGraph into BloodHound, these queries cover the most common needs. For more, see the per-implementation READMEs.

MATCH (p)-[r]->(s:NetworkShareSMB)
WHERE (p)-[:CanDelete]->(s)
  AND (p)-[:CanDsControlAccess]->(s)
  AND (p)-[:CanDsCreateChild]->(s)
  AND (p)-[:CanDsDeleteChild]->(s)
  AND (p)-[:CanDsDeleteTree]->(s)
  AND (p)-[:CanDsListContents]->(s)
  AND (p)-[:CanDsListObject]->(s)
  AND (p)-[:CanDsReadProperty]->(s)
  AND (p)-[:CanDsWriteExtendedProperties]->(s)
  AND (p)-[:CanDsWriteProperty]->(s)
  AND (p)-[:CanReadControl]->(s)
  AND (p)-[:CanWriteDacl]->(s)
  AND (p)-[:CanWriteOwner]->(s)
RETURN p,r,s

MATCH x=(p)-[r:CanWriteDacl|CanWriteOwner|CanDsWriteProperty|CanDsWriteExtendedProperties]->(s:NetworkShareSMB)
RETURN x

MATCH p=(h:NetworkShareHost)-[:HasNetworkShare]->(s:NetworkShareSMB)-[:Contains*0..]->(f:File)
WHERE toLower(f.name) = toLower("flag.txt")
RETURN p

MATCH p=(h:NetworkShareHost)-[:HasNetworkShare]->(s:NetworkShareSMB)-[:Contains*0..]->(f:File)
WHERE toLower(f.extension) = toLower(".vmdk")
RETURN p

MATCH p=(principal)-[:CanEffectiveRead]->(f:File)
RETURN p
