Preventing Puppeteer Detection

Preventing-Puppeteer-Detection.md

I’m looking for any tips or tricks for making chrome headless mode less detectable. Here is what I’ve done so far:

Set my args as follows:

const run = (async () => {

    const args = [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-infobars',
        '--window-position=0,0',
        '--ignore-certifcate-errors',
        '--ignore-certifcate-errors-spki-list',
        '--user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3312.0 Safari/537.36"'
    ];

    const options = {
        args,
        headless: true,
        ignoreHTTPSErrors: true,
        userDataDir: './tmp'
    };

    const browser = await puppeteer.launch(options);

I’m loading in a preload file that overrides some window.navigator globals:

    const preloadFile = fs.readFileSync('./preload.js', 'utf8');
    await page.evaluateOnNewDocument(preloadFile);

preload.js

// overwrite the `languages` property to use a custom getter
Object.defineProperty(navigator, "languages", {
  get: function() {
    return ["en-US", "en"];
  };
});

// overwrite the `plugins` property to use a custom getter
Object.defineProperty(navigator, 'plugins', {
  get: function() {
    // this just needs to have `length > 0`, but we could mock the plugins too
    return [1, 2, 3, 4, 5];
  },
});

I see there are some other things suggested here https://intoli.com/blog/making-chrome-headless-undetectable/ but I'm not 100% certain how to implement them in puppeteer. Any ideas tips or tricks?

worked for me, now recaptcha isn't bothering me anymore. thanks!

In above gist, passing some arguments won't work because those are deprecated i.e no-infobars won't hide chrome is updated by automated script info bars as chrome teams has removed this as security bug.
instead pass another array to launch method
ignoreDefaultArgs: ["--enable-automation"]

" Object.defineProperty(navigator, 'webdriver', { get: () => false, }); " cant work,it is not enought ,because after that input " 'window' in navigator ",the result is 'True'. it still will be detected.

Better to use:

const newProto = navigator.__proto__;
delete newProto.webdriver;
navigator.__proto__ = newProto;

" Object.defineProperty(navigator, 'webdriver', { get: () => false, }); " cant work,it is not enought ,because after that input " 'window' in navigator ",the result is 'True'. it still will be detected.

solve WebDriver (NEW) for me

Works on localhost for me, fails on remote vps
