Cybersecurity student seeking a penetration testing role in Germany, with PNPT hands-on experience compromising Active Directory environments.
GermanyWhat I'm looking for
In my PNPT simulated penetration test engagement with TCM Security, I assessed an Active Directory environment, pivoted into the internal network, and escalated to full domain privileges. I delivered a professional penetration-test report and passed a live, client-style debrief.
Through ongoing Hack The Box labs, I’ve practiced Active Directory attack paths, including RBCD abuse, AD CS enumeration, and Kerberos relay. I also designed and operate a self-hosted VPN service with a Python Telegram-bot front end and a WireGuard backend.
