What Exploiting Active Directory with BloodHound does
The Exploiting Active Directory with BloodHound skill provides a robust framework for red teams and security professionals to leverage BloodHound, a graph-based tool designed for Active Directory reconnaissance. By employing graph theory, BloodHound uncovers hidden relationships within Active Directory environments, enabling users to identify potential attack paths from compromised accounts to high-value targets like Domain Admins. This skill is particularly useful for those involved in penetration testing and security assessments, as it allows for the visualization of privilege escalation opportunities that are often overlooked in manual assessments.
Using BloodHound, practitioners can collect data on Active Directory objects, relationships, and access control lists (ACLs) through the SharpHound collector. This data is then analyzed to reveal attack paths, misconfigurations, and potential vulnerabilities within the AD environment. The skill guides users through the entire process, from data collection to exploitation planning, ensuring that all critical steps are documented and validated. This structured approach not only enhances the effectiveness of security testing but also aids in building detection capabilities based on offensive techniques.
This skill is ideal for security professionals who are familiar with red teaming concepts and are looking to deepen their understanding of Active Directory exploitation techniques. It requires a controlled environment for execution, ensuring compliance with legal and ethical standards. By employing this skill, users can systematically identify and exploit vulnerabilities in Active Directory setups, ultimately improving the security posture of their organizations.
In summary, the Exploiting Active Directory with BloodHound skill equips users with the necessary tools and methodologies to conduct thorough security assessments of Active Directory environments, making it an essential addition to any red team toolkit.

Overview
BloodHound is a graph-based Active Directory reconnaissance tool that uses graph theory to reveal hidden and unintended relationships within AD environments. Red teams use BloodHound to identify attack paths from compromised accounts to high-value targets such as Domain Admins, identifying privilege escalation chains that would be nearly impossible to find manually. SharpHound is the official data collector that gathers AD objects, relationships, ACLs, sessions, and group memberships.
When to Use
- When performing authorized security testing that involves exploiting active directory with bloodhound
- When analyzing malware samples or attack artifacts in a controlled environment
- When conducting red team exercises or penetration testing engagements
- When building detection capabilities based on offensive technique understanding
Prerequisites
- Familiarity with red teaming concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities
Objectives
- Collect Active Directory relationship data using SharpHound or BloodHound.py
- Visualize attack paths from compromised accounts to Domain Admin
- Identify misconfigured ACLs, group memberships, and delegation settings
- Discover shortest attack paths to high-value targets
- Map Kerberos delegation configurations for abuse
- Document all identified privilege escalation chains
MITRE ATT&CK Mapping

- T1069.002 - Permission Groups Discovery: Domain Groups
- T1482 - Domain Trust Discovery
- T1615 - Group Policy Discovery
- T1018 - Remote System Discovery
- T1033 - System Owner/User Discovery
- T1016 - System Network Configuration Discovery
Workflow
Phase 1: Data Collection with SharpHound
- Transfer SharpHound collector to compromised host
- Execute collection with appropriate method (All, DCOnly, Session, LoggedOn)
- Collect from all reachable domains if multi-domain environment
- Exfiltrate ZIP data files to analysis workstation
- Import data into BloodHound CE or Legacy
Phase 2: Attack Path Analysis
- Mark owned principals (compromised accounts)
- Query shortest path to Domain Admins
- Identify Kerberoastable accounts with admin privileges
- Find AS-REP Roastable accounts
- Analyze ACL-based attack paths (GenericAll, GenericWrite, WriteDACL, ForceChangePassword)
- Review GPO abuse opportunities
Phase 3: Exploitation Planning
- Prioritize attack paths by complexity and stealth
- Identify required tools for each step in the chain
- Plan OPSEC considerations for each technique
- Execute identified attack chain
- Document evidence at each step
