Hi, I'm Yalguun - an internationally certified Cyber Security Trainer, Ethical Hacker, and Vulnerability Researcher. I hold globally recognized certifications including OSCE3, OSCP, CPENT, and SRT, and I have trained over 500 engineers and students in cybersecurity through online programs.
I have discovered 30+ CVEs in major open-source projects including Apache Airflow, JupyterLab, Angular, Node.js, and Grafana, and reported validated vulnerabilities to the U.S. Department of Defense, AWS, Crypto.com, Django, curl, and Monero through Google VRP & HackerOne bug bounty programs.
My work focuses on offensive security, vulnerability research, and practical cybersecurity education. Through this channel, I share technical knowledge, real-world security insights, and hands-on learning experiences to support the next generation of cybersecurity professionals.
