About

Hi, I'm Amar Bhattarai — an IT professional focused on cybersecurity, Windows administration, and enterprise networking.

I started this blog to document the things I learn and troubleshoot in real environments: securing Windows systems, managing devices with Microsoft Intune, understanding emerging threats like ransomware and cryptojacking, and evaluating the security implications of new technologies such as AI assistants built into the operating system.

What You'll Find Here

• Security — practical threat analysis, hardening guides, and explanations of attacks like ransomware, phishing, and prompt injection, written in plain English.
• Windows — administration tips, Group Policy and registry configurations, and step-by-step guides for features like BitLocker, Credential Guard, and Copilot.
• Networking — firewall configuration, DNS filtering, telemetry analysis, and network-level privacy controls.
• Tools — reviews and walkthroughs of open-source and enterprise tools I actually use, from Wireshark to Pi-hole to Microsoft Intune.

Why Trust This Blog

Every guide published here is tested on real systems before it goes live. When I cover a security topic, I cite the original research and link to primary sources. When something is my opinion rather than established fact, I say so clearly. If you spot an error, I genuinely want to hear about it — use the Contact page and I'll correct it.
