How To Discover Hidden Endpoints🕵️♂️
Free Article Link
🔍 Hidden endpoints often contain sensitive functionalities, unreleased features, or admin-only actions. Finding these endpoints can lead to IDORs, privilege escalations, and critical business logic flaws. Let’s explore advanced techniques to uncover them! 🛡️✨

1. Passive Discovery with JavaScript Analysis 📚🕵️♂️
🛠️ Tool: LinkFinder
⚙️
🧪 Method: Extract URLs from JavaScript files using regex-based scanning.
💻 Example Command:
python3 linkfinder.py -i https://target.com/script.js -o cli
💡 Tip: Look for endpoints like /admin
, /debug
, /beta
, or unusual API routes.
🔑 What to do after discovery?
- 🖱️ Manually visit each endpoint.
- 🔓 Test for authentication bypass by removing tokens.
- 🛡️ Attempt common parameters such as
?admin=true
or?debug=1
. - 🕵️ Check for sensitive data exposure.
2. Fuzzing for Undocumented APIs 🤔💥
🛠️ Tool: ffuf
🛠️
🧪 Method: Brute-force directories and API endpoints using wordlists.
💻 Example Command:
ffuf -u https://target.com/FUZZ -w wordlist.txt -mc 200,302
💡 Tip: Use custom wordlists for API discovery (e.g., SecLists/API directory
).
🔑 What to do after discovery?
- 🔍 Check for admin panels, beta features, or hidden functionality.
- 🛠️ Attempt fuzzing with parameters (e.g.,
ffuf -u https://target.com/api/endpoint?param=FUZZ
