# Cybersecurity Write-ups

Hands-on CTF write-ups and challenge notes.

## Cybersecurity Write-ups

Technical CTF write-ups based on completed, authorized lab investigations. This collection documents practical enumeration, exploitation, privilege escalation, and defensive lessons.

Each entry preserves the observed solve path. It separates evidence from conclusions and explains why each step mattered.
