CRTP Active Directory Walkthrough & Exam Reporting Guide

The Certified Red Team Professional (CRTP) by Altered Security stands as a premier benchmark for Active Directory exploitation. Success in this environment requires more than just running automated tools; it demands a deep, tactical understanding of built-in Windows features, Kerberos abuse, domain trusts, and delegation vulnerabilities.

Many students successfully breach the environment but fail the certification due to poor documentation or missing critical links in their attack chain. This walkthrough breaks down the exact exam environment structure, the technical hurdles you will face, and how to effectively map your path to enterprise compromise.

Exploitation Methodology: tech.corp & finance.corp

To successfully compromise the infrastructure, you must systematically dismantle the domain. Starting from your initial foothold on studvm.tech.corp, the exam requires meticulous enumeration. Establishing an attack path involves identifying specific misconfigurations and moving laterally through the network without triggering unnecessary alerts. The environment is heavily patched, meaning standard CVE exploits will likely lead you down time-consuming rabbit holes.

Pivoting through systems like mgmtsrv.tech.corp and techsrv30.tech.corp often involves exploiting Resource-Based Constrained Delegation (RBCD) or unconstrained delegation. You will need to expertly manipulate Service Principal Names (SPNs) and forge Kerberos tickets to impersonate privileged users. As you elevate your privileges, compromising adminsrv86.tech.corp becomes a crucial stepping stone to executing a DCSync attack against the primary domain controller: tech-dc.tech.corp.

Conquering the Forest Trust

The final hurdle tests your understanding of Active Directory forest trusts. Securing Domain Admin on the tech.corp domain is not the end of the engagement. To achieve full enterprise compromise, you must leverage your newly acquired privileges to bridge the forest trust and fully compromise finance-dc.finance.corp.

This phase requires a deep understanding of trust key extraction and inter-forest ticket forgery. Documenting this exact sequence with precise command syntax is mandatory. Every step, from initial bloodhound data collection to the final golden ticket generation across the forest, must be recorded meticulously. Whether you are reviewing exam strategies or searching for documentation templates, having everything all at one place drastically reduces your prep time and ensures you are fully equipped for the 24-hour exam window.
