About Me
I’m a cybersecurity enthusiast currently studying at Ho Chi Minh City University of Technology (HCMUT), and a member of BKISC. My main area of interest is red team, web exploitation and real-world vulnerability research. I enjoy breaking, analyzing, and understanding the internals of modern applications, and writing about them.
Focus Areas
- Web vulnerabilities: XSS, SQLi, IDOR, SSTI, logic bugs
- Analyzing obfuscated or malicious JavaScript/PHP
- Studying CVEs and developing PoCs
- Occasionally explore binary exploitation and malware behavior
