Hi, this is
Quoc Thai
Information Security Student | Aspiring Pentester | CTF Player
I focus on penetration testing, vulnerability assessment, and hands-on security labs, using tools such as Kali Linux, Nmap, and Metasploit.
I regularly take part in CTF challenges and Hack The Box labs to sharpen my skills, and document what I learn through write-ups.

About
I am a third-year Information Security student aspiring to become a Penetration Tester. I am learning to assess system and web application security, identify vulnerabilities, and practice ethical exploitation in controlled labs.
I regularly solve CTF challenges, practice on Hack The Box, and build hands-on labs to improve my reconnaissance, enumeration, vulnerability assessment, and reporting skills.
