Cybersecurity fundamentals
The core ideas everything else rests on: how networks and operating systems work, common threats like phishing and malware, passwords and authentication, and why updates matter.

Cybersecurity. Automation. Real-World Tech Skills.
Krang Tech is a place to explore cybersecurity, automation, and practical technology skills. Learn about security concepts, discover useful tools, and follow hands-on technology projects.
About Krang Tech
Krang Tech is an educational brand focused on the practical side of technology: understanding how systems are attacked, how to defend them, and how to automate the everyday work of keeping a computer healthy and secure.
The approach is hands-on and beginner-friendly. Concepts are explained in plain language, tools are shown in real use, and everything is done in the open, including the mistakes and the fixes.
- Practical first. Skills you can apply on your own machine.
- Plain explanations. No gatekeeping, no unnecessary jargon.
- Ethical by default. Security testing only on systems you own or have permission to test.
Cybersecurity Learning
Cybersecurity can feel overwhelming at first. Krang Tech breaks it into three areas that build on each other.
Ethical security testing
Learning how attackers think, in safe and legal environments: home labs, virtual machines, and practice platforms built for hands-on challenges. Always with permission, never on someone else's systems.
Defensive security practices
Protecting what you already have: hardening Windows settings, reviewing what runs at startup, monitoring your system, and building habits that keep accounts and devices safe.
Automation & Scripts
Krang Tech will feature useful automation projects, PowerShell scripts, and technical resources for Windows users who want their computers to do more of the work.
PowerShell for everyday tasks
Short, readable scripts for maintenance and monitoring: checking disk space, reviewing updates, cleaning temporary files, and auditing startup programs.
Open source on GitHub
Scripts are published in a public GitHub repository, so anyone can read the code, learn from it, and suggest improvements.

Never run a script from the internet without reading it first, including these. Every Krang Tech script is written to be understood, with comments that explain each step.
Technology Projects
Hands-on projects that turn concepts into real skills. These are the kinds of builds Krang Tech focuses on:
Home lab builds
Setting up virtual machines, including security-focused Linux distributions, to create a safe space for experiments.
Windows hardening
Reviewing privacy and security settings step by step, and understanding what each change actually does.
Tool walkthroughs
Practical looks at security and system tools: what they are for, how to use them responsibly, and what their output means.
AI and security
Exploring where artificial intelligence and cybersecurity meet, from how AI models can be audited to the risks in their supply chains.
