How to capture trackers like cookies, pixels, etc., used on a remote website?

We are working on a project similar to CookieBot as part of a larger project to protect personal data and information of web users. The aim is to obtain comprehensive information about tracking and profiling techniques so that the user can decide for themselves whether to allow their use. But prior owner of website has to know it.

How can we access a website in such a way that we can intercept requests and cookies?

Solution

  • You could try with which allows you to script Chrome (or Chromium) via JavaScript.

    In this example:

    1. I go to this page
    2. I print all requests going out from this page
    3. I print all cookies set page this page
    // pptr.js
const puppeteer = require('puppeteer-core');

module.exports = async () => {
  const browser = await puppeteer.connect({ browserWSEndpoint: 'ws://localhost:3001' });
  const page = await browser.newPage();
  page.on('request', req => {
    console.log(`request: ${req.url()}`);
  });
  await page.goto('https://stackoverflow.com/q/64901406/1244884');
  const cookies = await page.cookies();
  console.log('Cookies:');
  cookies.forEach(cookie => {
    console.log(`${cookie.name}\t${cookie.value}`);
  });
  await browser.close();
};

    Which you can run as follow:

    node -p -e 'require("./pptr.js")()'

    Output:
