CRTO review (Certified Red Team Operator)

Red Teaming is a cybersecurity assessment that involves adversary simulation, using real-world TTPs (Tactics, Techniques, and Procedures) to mimic advanced threats, test defenses, and improve an organisation’s security posture.

Overview

➡️ I’ve earned the CRTO badge from Zero-Point Security. What I really liked about this course is that it has a good mix of explanations and hands-on exercises in the SnapLabs environment.

The Certified Red Team Operator certification is an advanced course in offensive security, focusing primarily on the use of Cobalt Strike, one of the main trade tools. The course, exam, and all aspects of Zero Point Security are overseen by RastaMouse.

Key Takeaways from the Course

✅ Highly Recommended – Covers essential Red Team concepts.
✅ Hands-on Experience – Work with Cobalt Strike C2 in a fully functional lab.
✅ Lifetime Access – Get free course updates and revisit materials anytime.

What I Really Liked About CRTO

One of the best parts of this course was the deep hands-on experience with Cobalt Strike and Red Teaming methodologies. Here’s what stood out:

• Hands-on Experience with Cobalt Strike C2 – Practical exercises covering beacon management, payload staging, and real-world attack simulation.
• Working with Artifacts in Cobalt Strike – Customizing artifact kits to improve payload OPSEC and evasion.
• Building a Custom C2 Profile – Crafting a Malleable C2 profile and learning how adversaries mimic legitimate traffic.
• Bypassing Windows Defender – Learning the methodology of systematically bypassing Windows Defender.
• Understanding Red Teaming Configurations – Gaining insight into Cobalt Strike infrastructure, OPSEC configurations, and stealth techniques.
• No Report Submission Needed – The exam is purely technical, and if you capture at least 6 flags, you pass automatically—no need to submit a report! However, flag submission is required to pass.
• Get Your Digital Certificate – Once you pass, create an account on Badgr with the same email address you registered at training.zeropointsecurity.co.uk to claim your digital certificate.

Simulation of Real-World Attacks

The course teaches tactics, techniques, and procedures (TTPs) to simulate real-world threats, allowing security teams to test and enhance their detection and response capabilities while strengthening an organisation’s overall security posture.

Who Should Take CRTO?

This course is ideal for professionals looking to gain practical Red Teaming experience, especially with Cobalt Strike.

✅ Penetration Testers who want to transition into Red Teaming.
✅ Security Analysts & SOC Teams who want to understand real-world adversary techniques.
✅ Aspiring Red Teamers who want to master Cobalt Strike, OPSEC, and evasion.
✅ Defensive Security Professionals who want insight into how attackers bypass security controls.

Understanding TTPs (Tactics, Techniques, and Procedures)

TTPs describe how attackers behave when compromising a system or network. Understanding them is crucial for effective defense. They are broken down into three categories:

1️⃣ Tactics

These are the high-level strategic goals of the attacker. They represent what the attacker is trying to achieve. Examples include:

• Privilege Escalation
• Lateral Movement
• Persistence
• Data Exfiltration
• Initial Access

2️⃣ Techniques

These are the specific methods or tools used to accomplish a tactic. They describe how the attacker achieves their goal. Examples include:

• Privilege Escalation: Kerberoasting, Pass-the-Hash, Exploiting known vulnerabilities.
• Lateral Movement: Pass-the-Hash, Remote Services, Valid Accounts.
• Persistence: Scheduled Tasks, Registry Keys, Backdoors.
• Data Exfiltration: FTP, HTTPS, DNS Tunneling.
• Initial Access: Phishing, Exploit public facing application.

3️⃣ Procedures

These are the step-by-step implementations of specific techniques within a particular attack. They describe the specific way an attacker uses a technique in a given scenario.

Procedures are often unique to an attacker or campaign and provide the most granular level of detail. For example, a procedure might describe the exact sequence of commands used in a Pass-the-Hash attack, including the specific tools and parameters executed.

---

Summary:

• Tactics: The attacker’s goal.
• Techniques: The methods used to achieve the goal.
• Procedures: The specific implementation of a technique.

By understanding TTPs, defenders can better anticipate, detect, and respond to attacks, strengthening overall security posture.
