Think out of the box

Hi, I am Red Team security engineer at Viettel Cyber Security. My work focuses on reconnaissance, web exploitation, and security research.

Recently, I have been expanding my focus into Web3 security and AI attack surfaces, particularly around smart contracts, AI agents, LLM applications, prompt injection, insecure tool usage, and data leakage risks.
