- Decoding the CAPE Exam: A 10-Day Battle of Endurance and Skill
The CAPE exam is not a simple multiple-choice test; it is a hands-on, immersive simulation. Candidates have 240 hours to infiltrate a simulated enterprise AD network, capture at least 9 out of 10 flags, and compile a client-ready report. A minimum score of 90 points is required to pass, with scoring heavily weighted towards the technical report’s quality. This format mirrors a real-world penetration testing engagement, where technical findings are meaningless without clear communication and actionable remediation advice.
Step‑by‑step guide explaining what this does and how to use it.
Step 1: Fulfill the Prerequisite. You cannot simply sign up for CAPE. Access is mandatorily gated by the complete “Active Directory Penetration Tester” job-role path on HTB. This path consists of 15 modules covering foundational to advanced topics.
Step 2: Schedule and Strategize. Once eligible, schedule your 10-day exam window. Prepare your environment: have at least two VMs ready (one Linux for attack, one Windows for testing and compiling tools). Organize your note-taking system (e.g., Obsidian, OneNote) for meticulous logging.
Step 3: Execute the Engagement. Treat the exam like a real job. The first 8-9 days should be dedicated to thorough enumeration, exploitation, and lateral movement. Do not leave report writing for the last day. Document findings as you go.
Step 4: The Final Sprint: Reporting. Dedicate the final 24-48 hours exclusively to report writing. Structure it professionally: Executive Summary, Methodology, Detailed Findings (with evidence screenshots for each flag), Risk Ratings, and Technical Recommendations. This report is a critical scoring component.
2. Foundational Preparation: Building Your AD Assault Toolkit
Success in CAPE is built long before the exam starts. It requires a solid foundation in general penetration testing and specific AD knowledge. As noted by the certified professional, completing the HTB Certified Penetration Testing Specialist (CPTS) path first is highly recommended. Furthermore, hands-on practice in complex labs is invaluable for building the “outside-the-box” thinking the exam demands.
Step‑by‑step guide explaining what this does and how to use it.
Step 1: Solidify Core Pentesting Skills. Complete the HTB CPTS path. This ensures you are proficient in network attacks, web app vulnerabilities, and basic privilege escalation, which are all assumed knowledge in CAPE.
Step 2: Train in Advanced Scenarios. Enroll in and complete the Cybernetics and Ifrit ProLabs on HTB. These labs provide concentrated practice on exam-relevant skills like AV/EDR evasion, complex pivoting, and advanced lateral movement.
Step 3: Set Up a Personal AD Lab. Clone and deploy the GOAD (Game of Active Directory) Lab on GitHub. This vulnerable lab allows you to practice techniques at your own pace. Use it to experiment with tools like `Certipy` and Rubeus.
Example: Cloning and deploying the GOAD lab for practice git clone https://github.com/Orange-Cyberdefense/GOAD cd GOAD Follow the provider-specific (VirtualBox/VMware) setup guide in the README
- The Art of Deep Enumeration: Seeing What Others Miss
The key differentiator between a good and an elite tester is the depth of enumeration. The CAPE exam heavily punishes superficial scanning. Flags are hidden behind layers of misconfigurations. As the experience shared indicates, if a service or permission doesn’t behave as expected, that is the starting point, not a dead end.
Step‑by‑step guide explaining what this does and how to use it.
Step 1: Beyond Basic Scans. Move past simple `nmap` scans. Use AD-specific enumeration tools from your Linux attack box to map the entire domain structure, users, groups, and trusts.
Using ldapsearch for deep AD enumeration ldapsearch -H ldap://<DOMAIN_CONTROLLER_IP> -x -b "dc=target,dc=local" -D "cn=bind_user,dc=target,dc=local" -w 'P@ssw0rd!' "(objectClass=)" > full_ldap_dump.txt Using BloodHound-ingestor from Linux python3 bloodhound.py -u 'user' -p 'password' -d target.local -ns <DC_IP> -c All
Step 2: Analyze Privilege Relationships. Ingest collected data into BloodHound on your attack machine. Analyze not just direct privileges, but group nesting, GenericAll, GenericWrite, Owns, and `WriteDACL` edges that can be chained for pathfinding.
Step 3: Enumerate Everything, Twice. Manually check Certificate Authorities (Certipy), GPOs, DNS records, and SMB shares. Cross-reference findings. A user with `WriteOwner` on a group that has local admin rights on a server is a golden ticket.
- Exploiting DACL Misconfigurations: The Heart of AD Privilege Escalation
Discretionary Access Control List (DACL) abuses form the backbone of many advanced AD attacks. The CAPE course’s DACL Attacks I & II modules are cited as particularly critical for exam success. Understanding how to identify and exploit permissions likeWriteOwner,WriteDACL, and `ForceChangePassword` is essential.
Step‑by‑step guide explaining what this does and how to use it.
Step 1: Identify Vulnerable Permissions. Using BloodHound or manual `PowerView` queries, find objects (users, groups, computers) where you have malicious write permissions.
PowerShell/PowerView example to find objects where the current user has WriteProperty
Get-DomainObjectAcl -Identity | ? {$<em>.SecurityIdentifier -eq $(Get-DomainUser -Identity currentuser -Properties objectsid).objectsid} | ? {$</em>.ActiveDirectoryRights -match "WriteProperty"}
Step 2: Execute the Abuse. Based on the permission, choose your attack. For ForceChangePassword, reset a privileged user’s password. For WriteOwner, take ownership of an object, then modify its DACL to grant yourself full control.
Example: Using PowerView to force change a user's password after identifying the right Set-DomainUserPassword -Identity 'TargetAdmin' -AccountPassword (ConvertTo-SecureString 'NewP@ssw0rd!' -AsPlainText -Force)
Step 3: Chain the Access. Use your newly gained access (e.g., as a domain admin) to extract credentials (DCSync) or move laterally to capture the target flag.
5. Weaponizing Custom Binaries for Evasion and Execution
A recurring theme in advanced exams is the need to adapt to the target environment. The CAPE exam requires you to compile custom C tools on a Windows machine to bypass defenses or achieve execution. This tests your ability to operate outside a standardized Kali toolkit.
Step‑by‑step guide explaining what this does and how to use it.
Step 1: Prepare Your Windows Environment. Have a Windows VM with Visual Studio or the `.NET SDK` installed. This is your compilation workstation.
Step 2: Modify and Compile Tools. You may need to modify a public exploit (e.g., from the `GhostPack` collection like `Rubeus` or Seatbelt) to change signatures or functionality. Clone the repo, make the code change in the .csproj, and compile.
On Windows, using the .NET SDK to compile a C project git clone https://github.com/GhostPack/Rubeus.git ... modify code ... cd Rubeus msbuild Rubeus.sln /p:Configuration=Release
Step 3: Transfer and Execute. Use a covert method (certutil, SMB, a simple web server) to transfer the compiled `.exe` to the target and execute it to proceed with your attack chain.
What Undercode Say:
- The Gap Between Learning and Application is Where Mastery Lives: The CAPE exam successfully bridges the gap between understanding isolated AD techniques and applying them in a chaotic, realistic network. It proves that true expertise lies not in memorization, but in adaptive problem-solving and meticulous documentation under extended pressure.
- Depth Over Breadth Defines Elite Certifications: Unlike certifications that survey a wide surface area, CAPE’s value is in its obsessive depth on a single domain—Active Directory. It validates an individual’s ability to not just run tools, but to understand the underlying protocols, trust models, and security descriptors at a fundamental level, making them capable of discovering novel attack paths.
Analysis: The CAPE certification represents a significant evolution in practical security credentialing. It moves beyond controlled, solvable machines to a sustained engagement that mirrors client work, complete with reporting—a skill often neglected in technical training. The emphasis on mandatory pre-requisite paths ensures a baseline, while the exam’s difficulty guarantees that those who pass have genuinely internalized the material. This model effectively filters for persistence, ingenuity, and professionalism, producing individuals who are immediately valuable to advanced red teams and penetration testing units. The recommendation to complete other complex HTB labs like Cybernetics after CAPE, and find them “easy,” is a powerful testament to its skill-sharpening effect.
Prediction:
The CAPE exam is a bellwether for the future of cybersecurity certifications. We will see a rapid decline in the value of multiple-choice or single-machine exams and a rise in multi-day, scenario-based assessments that test both technical skill and soft skills like reporting and time management. Employers will increasingly use these “expert-level” certifications as reliable hiring filters for senior offensive roles. Furthermore, as AD continues to be the backbone of enterprise networks and a prime target for actors like ransomware groups, the specialized, in-depth knowledge validated by CAPE will become a critical and highly sought-after defense capability, pushing more professionals toward this type of deep, specialized training.
