How to Use reverse-skill for Windows AD and Cloud Kubernetes Security Tasks

You can use reverse-skill to automate Windows Active Directory and Cloud/Kubernetes security assessments by invoking a modular routing system that maps high-level hints to concrete attack playbooks, enforced by mandatory authorization workflows.

The reverse-skill repository (zhaoxuya520/reverse-skill) provides a platform-agnostic "skill-router" that enables security analysts to execute targeted penetration testing and red team operations across heterogeneous environments. By abstracting complex attack chains into standardized skill packages, the framework ensures repeatable, documented workflows for both on-premise Windows domains and cloud-native Kubernetes clusters.

Understanding the reverse-skill Architecture

The framework operates through three core components that manage execution flow from initial hint to final script invocation.

The Routing Matrix

At the heart of reverse-skill lies the routing matrix defined in skills/routing.md, which maps descriptive hints (e.g., "Kerberos/AD" or "K8s privilege escalation") to concrete skill directories. The master-route entry points—skills/scripts/master-route.ps1 for Windows and skills/scripts/master-route.sh for Linux/macOS/Kali—parse these hints by referencing skills/config/routing.json to dispatch execution to the appropriate skill package.

Case Guard and Authorization

Every security task requires explicit legal authorization through the case-guard workflow. Before any active engagement, analysts must:

• Initialize a case using case-init.ps1 (or case-init.sh on Unix-like systems)
• Define scope in work/<case>/scope.md
• Obtain an auth.status=granted flag via case-guard.ps1 (or case-guard.sh)

This enforcement mechanism prevents unauthorized execution regardless of the target environment.

Windows Active Directory Security Tasks

Reverse-skill treats Windows AD as a first-class citizen with dedicated skill packages for domain enumeration and privilege escalation.

AD Skill Structure

The Windows AD skill resides in skills/windows-ad/, with meta-information defined in skills/windows-ad/SKILL.md. This directory contains documentation and PowerShell scripts targeting:

• Kerberos ticket-relay attacks
• AD Certificate Services (AD CS) misuse via Certipy
• BloodHound path analysis
• Domain privilege-escalation chains

Running AD CS Attacks with Certipy

To execute a certificate abuse chain against a domain controller, use the following workflow:

# Initialize a case with explicit scope (requires auth.status=granted)

.\skills\scripts\case-init.ps1 -Hint "AD CS certipy attack"

# Verify guard is ready

.\skills\scripts\case-guard.ps1

# Execute the Certipy script (provided by the AD skill)

.\skills\windows-ad\scripts\certipy.ps1 -TargetDC "dc01.corp.local" -User "admin"

The certipy.ps1 script encapsulates the command-line arguments and error handling required for AD CS exploitation, ensuring consistent execution across engagements.

Cloud and Kubernetes Security Operations

For cloud-native environments, reverse-skill provides equivalent automation through the k8s/ skill directory, following the same routing and authorization patterns established for Windows AD.

K8s Privilege Escalation Workflows

The Kubernetes skill (skills/k8s/SKILL.md) bundles kubectl wrapper scripts, Helm/YAML helpers, and reference guides for containerized attack vectors including pod eviction and service account abuse. Execute cluster enumeration through the standardized workflow:

# Start a case for a Kubernetes cluster

bash skills/scripts/case-init.sh --hint "K8s privilege escalation"

# Ensure the guard is satisfied

bash skills/scripts/case-guard.sh

# Use the bundled helper to enumerate cluster role bindings

bash skills/k8s/scripts/enum-rbacs.sh --kubeconfig /path/to/kubeconfig

Cross-Platform Execution

Because the router is platform-agnostic, the same hint works across operating systems with only the host-specific wrapper changing. Invoke the master router directly for instant dispatch:

# One-liner that routes a hint to the correct skill

powershell -NoProfile -ExecutionPolicy Bypass -File skills/scripts/master-route.ps1 -Hint "Kerberos domain pentest"

Required binaries for each skill—such as certipy, bloodhound, and kubectl—are indexed in skills/tool-index.md (auto-generated) to ensure prerequisite validation before execution.

Summary

• reverse-skill uses a routing matrix (skills/routing.md) to map high-level hints to concrete attack playbooks in skills/<category>/ directories.
• Authorization enforcement requires case-init and case-guard workflows with explicit auth.status=granted flags and scope documentation.
• Windows AD operations leverage skills/windows-ad/SKILL.md and PowerShell scripts for Kerberos, AD CS, and BloodHound operations.
• Kubernetes assessments utilize skills/k8s/ with bash scripts for RBAC enumeration and privilege escalation.
• Cross-platform compatibility is achieved through separate master-route.ps1 and master-route.sh entry points that consume the same routing.json configuration.

Frequently Asked Questions

What is the routing matrix in reverse-skill?

The routing matrix is a mapping system defined in skills/routing.md and implemented in skills/config/routing.json that translates human-readable hints (like "Kerberos/AD" or "K8s privilege escalation") into filesystem paths pointing to specific skill directories. When you provide a hint to the master-route script, it looks up the corresponding entry and loads the skill's SKILL.md file and associated scripts.

How does reverse-skill enforce authorization before execution?

Reverse-skill implements a case-guard workflow requiring analysts to run case-init to create a scoped engagement directory containing work/<case>/scope.md, followed by case-guard to verify the auth.status=granted flag. Neither the master router nor individual skill scripts will execute active operations unless this authorization state is present, ensuring legal compliance before any packets are sent or commands are run.

Can reverse-skill run on both Windows and Linux?

Yes. The framework provides platform-specific entry points—master-route.ps1 for Windows and master-route.sh for Linux/macOS/Kali—that both consume the same skills/config/routing.json configuration. This design allows security teams to use identical hints and skill logic across heterogeneous operating systems while maintaining native script execution (PowerShell for Windows AD tasks, Bash for K8s operations).

Where are the tool dependencies documented?

Required binaries and their installation sources are catalogued in skills/tool-index.md, which is auto-generated to reflect the specific tools needed for each active skill (e.g., certipy for AD CS attacks, kubectl for Kubernetes operations). This index ensures analysts can verify prerequisites before initiating the case-guard workflow.
