This technique helps uncover hidden keywords in scripts and resources on web pages. Here’s how to implement it:
Step 1 – Visit the Target Page
Open the target website (e.g., www.target.com) in Chrome, Brave, or Firefox.
Step 2 – Open Developer Tools
Right-click → Inspect → Go to the Console tab → Refresh the page (F5).
Step 3 – Paste PART ONE of the Script
Copy and execute the first part of the script from:
https://lnkd.in/e6NjPuzq
Step 4 – Paste PART TWO for Deep Analysis
After running PART ONE, paste the following:
foundMethods.forEach((entry, i) => {
console.log(<code>${String(i + 1).padStart(2, ' ')}. ${entry.path}</code>);
console.log(entry.value + '\n');
});
Note: You must run PART ONE first to define foundMethods.
Custom Keywords for Better Results
Modify the default keywords in PART ONE based on your target. Use regex to match hidden APIs, endpoints, or obfuscated functions.
You Should Know:
1. Extracting Hidden JavaScript Functions
Use this command to list all functions in the DOM:
let functions = [];
let scripts = document.getElementsByTagName('script');
for (let script of scripts) {
if (script.src) {
fetch(script.src)
.then(res => res.text())
.then(code => {
let funcs = code.match(/function\s+([^\s(]+)/g);
if (funcs) functions.push(...funcs);
});
}
}
console.log(functions);
2. Finding API Endpoints
Search for URLs in scripts:
let urls = [];
document.querySelectorAll('script').forEach(script => {
if (script.src) urls.push(script.src);
else {
let matches = script.textContent.match(/https?:\/\/[^\s'"]+/g);
if (matches) urls.push(...matches);
}
});
console.log(urls);
- Linux Command to Extract URLs from a Page
Use `curl` and `grep` to find hidden endpoints:
curl -s https://target.com | grep -Eo 'https?://[^"]+' | sort -u
4. Windows PowerShell Alternative
(Invoke-WebRequest -Uri "https://target.com").Links | Select-Object href
5. Automating with Python
import requests
from bs4 import BeautifulSoup
url = "https://target.com"
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
scripts = soup.find_all('script')
for script in scripts:
if script.get('src'):
print("Found script:", script['src'])
What Undercode Say
This method is powerful for penetration testers and bug bounty hunters. By analyzing JavaScript, you can uncover hidden vulnerabilities like:
– Hardcoded API keys
– Undocumented endpoints
– Obfuscated malware
Try these additional commands:
- Extract cookies: `document.cookie`
- List event listeners: `getEventListeners(element)`
- Check for XSS sinks: `Array.from(document.querySelectorAll(”)).filter(el => el.onclick)`
For deeper analysis, use Burp Suite or OWASP ZAP to intercept and modify requests.
Expected Output:
A structured list of functions, endpoints, and hidden scripts from the target website.
