I am a student at the University of Engineering and Technology – VNU 👨‍🎓 and currently working at Viettel Cyber Security 💼, focusing on Purple Team operations and detection testing across security controls.

My work covers the full Purple Team lifecycle, including:

• Designing adversary scenarios and attack procedures based on real-world threat intelligence
• Executing adversary emulation in controlled environments
• Verifying detection and visibility across security products such as EDR, SIEM, and NDR

To support scalability and consistency, I also build AI-assisted automation, where I:

• Use LLMs and RAG to extract adversary behaviors from CTI reports
• Map extracted behaviors to MITRE ATT&CK techniques
• Generate executable test cases and procedures
• Accelerate detection gap analysis and bypass exploration within existing rule logic

In parallel, I conduct research on applying AI/ML in Cyber Security, with a focus on:

• Intrusion Detection Systems (IDS)
• Adversarial attacks and defenses
• Robustness and security of AI-powered models

I maintain a strong foundation in both offensive and defensive security, along with prior experience in networking, cloud, and system administration, enabling me to build and evaluate end-to-end security testing workflows.

Technologies I work with:

• Languages: Go, Python
• Cyber Security: MITRE ATT&CK, Automated Adversary Emulation (Caldera, Atomic Red Team, …)
• AI / ML: Machine Learning, Deep Learning, Adversarial Machine Learning
• LLMOps: Dify
• Cloud Platforms: AWS, GCP, Kubernetes
