Hello, my name is Vasty Kervens Guivaldo Desir, but in the digital world I'm known as RootedN00b — a cybersecurity professional operating on both sides of the threat landscape.
On the offensive side, I specialize in penetration testing, red team operations, and adversary simulation — breaking into networks legally and responsibly to expose weaknesses before real attackers do. My toolkit spans Active Directory exploitation, C2 infrastructure, lateral movement, privilege escalation, and defense evasion.
On the defensive side, I operate as a SOC Analyst and Threat Hunter — building detection logic, hunting adversaries through SIEM platforms (ELK/Splunk), and conducting DFIR investigations. Holding the CDSA from HackTheBox, I bridge the gap between red and blue team disciplines.
I hold certifications from Zero-Point Security, AlteredSecurity, TCM Security, HackTheBox, Fortinet, and Cisco — each backed by real, hands-on lab work in enterprise environments.
