Offensive Security | Adversary Simlation | Active Directory Exploitation
I’m Velkris, a red team operator and cybersecurity researcher focused on:
- Advanced Active Directory attack simulation and privilege escalation chains
- Adversary emulation aligned to MITRE ATT&CK for enterprise lab environments
- Tradecraft automation and operational tooling development
- Detection engineering and log correlation analysis for Blue Team validation
My approach blends hands-on offensive operations with defensive insight, emphasizing adversary methodology, detection evasion, and iterative learning.
Comprehensive lab-based portfolio covering:
- Active Directory Pentest Lab (Kerberoast, AS-REP, Ticket & Certificate attacks)
- ATT&CK-aligned Adversary Simulations
- GPU-Accelerated Password Auditing (Hashcat / RTX 3080)
- Red Team Toolkit Automation & SOPs
