reverse-skill Active Directory Security Assessment Capabilities: A Technical Deep Dive

reverse-skill provides a dedicated Windows/Active Directory skill that orchestrates authorized AD security engagements through automated enumeration, credential exploitation, and privilege escalation pathways while maintaining strict scope enforcement and evidence journaling.

The zhaoxuya520/reverse-skill repository delivers a comprehensive framework for conducting authorized Active Directory security assessments. Its dedicated Windows/AD skill integrates routing intelligence, tool verification, and automated evidence collection to guide penetration testers through complex enterprise environments. This article examines the seven core capabilities that enable reverse-skill to automate discovery, exploitation, and documentation phases of AD security testing.

Scope-Driven Authorization Controls

reverse-skill implements mandatory authorization checks before executing any Active Directory operation. According to skills/windows-ad/SKILL.md, the framework enforces domain controller (DC) scoping, validates poisoning and relay permissions, and requires explicit case-init enforcement at lines 10-13. This ensures every engagement respects predefined boundaries and maintains audit compliance throughout the assessment lifecycle.

Comprehensive AD Enumeration

The framework automates host and identity discovery using a multi-tool approach. As implemented in skills/windows-ad/SKILL.md (lines 31-38), reverse-skill leverages:

• Impacket (nxc smb) for SMB share and user enumeration
• Native PowerShell commands for host reconnaissance
• BloodHound/SharpHound for harvesting user, group, and trust relationships

# Enumerate SMB shares and domain users with Impacket

nxc smb 192.168.1.0/24 -u administrator -p 'Password123'

# Collect comprehensive AD data with BloodHound

bloodhound-python -d corp.local -u admin -p password -c All -ns 192.168.1.10

Attack Path Visualization and Prioritization

reverse-skill integrates BloodHound to visualize lateral-movement routes and identify high-value attack vectors. The system prioritizes Kerberoasting targets, ACL abuse opportunities, and delegation misconfigurations as documented in skills/windows-ad/SKILL.md (lines 39-47). This capability allows testers to map complex trust relationships and identify the shortest paths to domain dominance.

Credential-Focused Exploitation Techniques

The AD skill implements multiple credential extraction methods through integrated tooling.

Kerberoasting and AS-REP Roasting

reverse-skill identifies Service Principal Names (SPNs) and accounts lacking pre-authentication to extract crackable tickets. As detailed in skills/windows-ad/references/ad-attack-paths.md (lines 5-7), the framework supports both Rubeus for Kerberoasting and GetNPUsers for AS-REP roasting.

# Extract service tickets for offline cracking

Rubeus.exe kerberoast /target:corp.local /outfile:hashes.txt

# Identify un-pre-authenticated accounts

GetNPUsers.py corp.local/ -no-pass -usersfile users.txt

NTLM Relay and Coercion

The framework detects weak SMB signing policies and executes relay attacks using Responder and ntlmrelayx. According to skills/windows-ad/SKILL.md (lines 46-47), reverse-skill coordinates these tools to capture and relay authentication attempts against vulnerable endpoints.

# Start Responder to poison LLMNR/NBT-NS requests

responder -I eth0 -wrf

# Relay captured hashes to target systems

ntlmrelayx.py -tf targets.txt -smb2support -socks

Credential Dumping

reverse-skill integrates SecretsDump, lsassy, and Mimikatz for memory and registry extraction, requiring explicit authorization before execution as specified in skills/windows-ad/SKILL.md (lines 49-53).

# Extract secrets from remote host

secretsdump.py corp.local/administrator:'Password123'@192.168.1.10

Active Directory Certificate Services (AD CS) Abuse

The framework automates certificate template attacks against AD CS infrastructure. As documented in skills/windows-ad/SKILL.md (lines 45-46) and ad-attack-paths.md (lines 7-9), reverse-skill deploys Certipy to exploit ESC1 and ESC8 vulnerabilities.

# Request certificate using vulnerable template (ESC1)

certipy req -u administrator -p Password123 -target ca.corp.local -template VulnTemplate

# Exploit web enrollment endpoint (ESC8)

certipy relay -target http://ca.corp.local/certsrv/certfnsh.asp

Privilege Escalation Pathways

reverse-skill identifies and exploits multiple privilege escalation vectors through ACL misconfigurations and delegation abuse. According to skills/windows-ad/SKILL.md (lines 18-22), the framework targets:

• GenericAll/WriteDacl permissions for ACL-based elevation
• Constrained and unconstrained delegation configurations
• Potato-style token abuse for local privilege escalation

Automated Evidence Collection and Routing Architecture

Every command execution is recorded, sanitized, and persisted to the field-journal for future reuse and reporting. The central routing engine in skills/routing.md (line 181) maps AD-related keywords to the appropriate skill handlers, while the bootstrap mechanism automatically installs missing dependencies including Impacket, Certipy, and BloodHound when absent from the target environment.

Summary

• reverse-skill enforces mandatory authorization checks before executing any Active Directory operation through its DC scoping and case-init validation.
• Comprehensive enumeration combines Impacket, PowerShell, and BloodHound to harvest complete domain topology and identity data.
• Credential attacks include Kerberoasting, AS-REP roasting, NTLM relay, and memory dumping through integrated tools like Rubeus, Responder, and Mimikatz.
• Certificate abuse capabilities target ESC1 and ESC8 vulnerabilities using Certipy automation.
• Privilege escalation pathways exploit ACL misconfigurations, delegation trusts, and token manipulation techniques.
• Evidence journaling automatically records all activities to field-journal while the routing engine coordinates tool deployment and dependency management.

Frequently Asked Questions

How does reverse-skill ensure authorization before running AD attacks?

reverse-skill implements mandatory checks in skills/windows-ad/SKILL.md that validate domain controller scope, poisoning permissions, and case-init enforcement before executing any potentially disruptive command. This ensures compliance with authorized engagement boundaries and prevents accidental out-of-scope testing.

What tools does reverse-skill automatically install for AD assessments?

The bootstrap mechanism automatically deploys Impacket for SMB operations, Certipy for certificate abuse, BloodHound/SharpHound for domain visualization, and Mimikatz for credential extraction when these tools are not detected on the local system, ensuring consistent capability across different testing environments.

How does reverse-skill document evidence during AD penetration tests?

Every command executed through the AD skill is automatically recorded, sanitized for sensitive data, and written to the field-journal as documented in skills/windows-ad/SKILL.md (lines 80-84). This creates an immutable audit trail suitable for compliance reporting and retest verification.

Which AD CS attacks does reverse-skill support?

According to skills/windows-ad/references/ad-attack-paths.md, reverse-skill supports ESC1 attacks against vulnerable certificate templates and ESC8 exploits targeting web enrollment endpoints, both executed through automated Certipy integration to escalate privileges via certificate forgery or relay techniques.
