Muntazir Mehdi — Security Researcher
I'm an IT Support Analyst with a Cyber Security degree and a recently earned CPTS certification. By day, I manage endpoints, Active Directory, and keep systems running — but my real focus is on the offensive side.
Outside of work, I study how Windows works under the hood, practice attack chains on platforms like Hack The Box, and research how malware operates at a low level. I'm drawn to the intersection of system internals and offensive tradecraft — especially AV and EDR evasion.
Currently studying for: CRTP (Certified Red Team Professional) while digging deeper into Windows internals, malware development, and picking up C/C++ along the way.
Here are a few technologies I’ve been working with recently:
- Active Directory attacks & enumeration
- Windows internals & AV/EDR evasion
- Penetration testing (web & infrastructure)
- Malware development & analysis
- PowerShell, C/C++, & Python
