Challenge: TechCorp Robots.txt Revelation

Overview:
This is an easy web CTF challenge that mimics a corporate intranet (TechCorp). The goal is to discover an admin flag by following clues about web crawling and security misconceptions.

Flow:
- Visit the homepage (`index.html`) and view the page source. There is a hint that points to `/backup`.
- Visit `/backup` to read employee chat logs discussing how Google indexed their site and exposed the admin panel, leading them to "block" it with robots.txt.
- Check `robots.txt` to see the disallowed paths, which ironically reveal `/secureadmin.php` and `/note.txt`.
- Visit `note.txt` to find the admin's new credentials.
- Use the credentials to log in at `secureadmin.php` and retrieve the flag.

Flag:
CODED{R0B0TS_TXT_15_PUBL1C_1NF0}

Notes:
- The site uses simple PHP for the login logic.
- This challenge teaches that robots.txt is public and doesn't prevent access—it's just a suggestion to crawlers.
- Designed for beginners learning about web enumeration and common security pitfalls.
