Hello Everyone. Recently I completed Attacking and Defending Active Directory course offered by Pentester Academy. The following blog post is a simple review of the course.
CRTP is a certification offered by Pentester academy. It's given after clearing a 24-hour exam.
At first, I was surprised to see a course taking the assume breach approach against a generic pentesting approach taken up by some other leading courses in the market (no pun intended!).
Q. What's Assume Breach methodology?
A. In Assume breach methodology we assume that the organisation is already breached. The whole objective of the machine is to test the resilience of the organisation against a threat actor who might've already compromised the organisation. This helps organisations to test their security team's capacity to identify and stop an attacker who might've already compromised their network.
Once you subscribe to the course, you'd get access to the course videos and lab. As their page suggests, the course consists of 23 learning objectives spanning across various stages of the cyber kill chain.
The course videos were really crisp and beginner friendly. However, the course demands the student to know about basics of Active Directory. The Instructor Nikhil Mittal made it very clear that unlike OSCP, this course would be based on mis-configurations and abuse of functionality. This gives the attacks learned in the course more shelf time.
The Lab was really the best part of the course. It'd save a lot of headache of setting up an entire AD with various machines and roles. The team was also so supportive and replied whenever I had an issue in the lab. The tasks/objectives in the lab mainly revolve around the following:
Active Directory Enumeration
Local Privilege Escalation
Domain Privilege Escalation
Domain Persistence and Dominance
Cross Trust Attacks
Forest Persistence and Dominance
Defenses – Monitoring
Defenses and bypass – Architecture and Work Culture Changes
Defenses and Bypass – Deception
Defenses and Bypass – PowerShell
Exam:
The exam is a separate forest and it's an open secret that you would have to compromise 5 machines. The team makes it very clear about the objective being the command execution on those 5 machines. The team also makes it very clear that reporting plays an important role in the exam and a bad report with 5 machines compromised might lead to the student fail in the exam. However, I came to know from friends who gave the exam that a minimum of 3 machines have to be compromised and along with a great report (adding possible mitigations') will just suffice.
First Attempt: I took the exam right after my 1 month lab period and I failed! Yes, I failed in my first attempt partially due to some tools not giving the right Output. This was made pretty clear by the Lab team well before the exam but I wasn't well prepared (bad me eh! :-( )
Preparation: I knew something was not right. Initially I decided to give up on the exam because I enrolled in the course for the content it provides and the lab's they've got. However, after closely looking at the dumps I had, I know I foolish I was to depend on an output of 1 tool and I understood the importance of re-validation. Another important lesson I learnt was about "Attacker Intuition" plays a major role. If you have the right mind, you'd get the attack path really fast. I thank Anurag Srivastava and Bhanu Teja for throwing light on certain aspects of Attacker Intuition which really helped me think in the right direction.
Second Attempt: I got my hands on after couple of weeks of my first failed attempt and this time I cracked the exam within 4 hours and submitted report within the next 2. Got email from the team a day later. But the exciting part is that all critical systems falling one after another, just like in a Hollywood movie.
It's a great course. I recommend anyone who wants to get their hands-on on AD pentesting. Labs are great, Team is very supportive and Instructor was just awesome. As they claim, it's on holiday discount now. It's worth grabbing now. Visit Pentester Academy - Attacking and Defending AD.
