Muntazir Mehdi — Cyber Security Practitioner
I'm an IT Support Analyst with a Cyber Security degree. Right now, I spend my days fixing endpoints, managing Active Directory, and keeping systems running. But that's only half the story.
After hours, I'm in my home lab—breaking into machines, studying for CPTS, and building out attack scenarios. I self-host everything I can because there's no better way to learn than by running your own infrastructure and then trying to compromise it.
Currently digging into: Offensive Security, Linux internals, and malware development.
Here are a few technologies I’ve been working with recently:
- Windows & Linux administration
- Active Directory & Microsoft 365
- Docker & virtualization
- Network configuration & troubleshooting
- Scripting for repeatable fixes (PowerShell/Bash)
