My personal cybersecurity blog, live at denarzai.github.io.

I'm a BS Cybersecurity student at FAST NUCES Islamabad, and this blog documents everything I learn on the way to becoming a security professional — CTF walkthroughs, course reflections, and plain-language explanations of security concepts.

What's on the blog

• OverTheWire Bandit series — step-by-step walkthroughs of every level I've completed (Level 0 through Level 21 and counting), covering Linux fundamentals, SSH, file permissions, cron jobs, setuid binaries, and privilege escalation
• TryHackMe notes — writeups from the Pre-Security and Jr Penetration Tester paths
• Concept posts — how passwords are really stored, why HTTPS is not enough, SQL injection in the real world, what file metadata reveals about you
• Course reflections — Harvard CS50 Cybersecurity, including my final project on the Salt Typhoon APT campaign
