A successful CTF writeup serves as both a personal reference and a community resource. It bridges the gap between completing a challenge and understanding the underlying principles. 1. Introduction and Scope

The core of any penetration test is reconnaissance. Effective writeups detail the tools used to scan the target, such as: : Identifying open ports and services.

This section documents the transition from reconnaissance to active exploitation. It describes how a vulnerability—such as an ECB Oracle or a Password Spraying Attack—was identified and leveraged to gain a foothold on the system. 4. Privilege Escalation

Once initial access is achieved, the focus shifts to escalating privileges. Writeups detail the search for misconfigured SUID binaries, exploitable cron jobs, or kernel vulnerabilities. This phase is critical as it often leads to the final "root" flag. 5. Conclusion and Lessons Learned
