fingerprint injection makes browsers detectable as headless #178
Comments
|
It seems like using the "chrome" browser ( browsers: ["chrome"] ) is the only one triggering the detection. const { chromium } = require("playwright");
const { FingerprintInjector } = require("fingerprint-injector");
const { FingerprintGenerator } = require("fingerprint-generator");
async function runBrowser(device, os, browserType) {
const browser = await chromium.launch({
headless: false
});
// chrome, firefox, edge, safari
const { fingerprint, headers } = await new FingerprintGenerator().getFingerprint({
devices: [device],
operatingSystems: [os],
browsers: [browserType]
});
const context = await browser.newContext({
userAgent: fingerprint.navigator.userAgent,
colorScheme: 'dark',
viewport: {
width: fingerprint.screen.width,
height: fingerprint.screen.height,
},
extraHTTPHeaders: {
'accept-language': headers['accept-language'],
},
});
await new FingerprintInjector().attachFingerprintToPlaywright(context, { fingerprint, headers });
const page = await context.newPage();
await page.goto("https://arh.antoinevastel.com/bots/areyouheadless", { waitUntil: "load"});
const value = await page.evaluate(() => document.querySelector('#res p').textContent);
console.log(`Device: ${device} | Os: ${os} | Browser: ${browserType} | Status: ${value}`);
await browser.close();
} |

@steinpigs thanks for this test! |
|
any takers ? |

Sorry for the delay, I actually started looking into this last week - but unfortunately didn't come to any conclusion. The 'Are you headless' website seems to utilize some kind of ML-like regression, where it collects the browser fingerprint and then sends it to the server, which decides whether the fingerprint is valid or not. Since this is not an actual bot-protection service, the priority on this is a bit lower, but I'll definitely continue looking into this. Thanks for your patience! :) |
|
No problem, I understand. Thank you for the update. However, I wanted to mention that the injected evasions in the fingerprint-injector compromise the anonymity of the fingerprint, rendering it unusable. This is an important factor to consider. |

I'm not sure if this works here, but you should find a way to use 'new' in headless |
Thanks for the inputs, but that's not the issue here. |

Debugged this, It is getting flagged due to The https://arh.antoinevastel.com/bots/areyouheadless plugin has a check https://github.com/antoinevastel/fpscanner/blob/master/src/fpScanner.js#L119 |

@abhisheksurve45 So why did not fingerprint-suite set |
|
fingerprint-injector/fingerprint-injector.js without extraheader will pass the detection. |
Removing accept-language will fix this issue: |

Can confirm @tenkuken patch works! I added |

@barjin Are you planning a fix or customizable header settings that don't involve forking this? The That way: |

@barjin Isn't the guy from that page https://arh.antoinevastel.com/bots/areyouheadless working for Datadome a bot-detection company. Which would make this maybe a priority? |
|
@iwaduarte Make it your priority then :) PRs are welcome. Regarding the fix - I would rather not add another option in the already pretty granular options object. The other problem is that by removing the A proper solution would include hiding the headlessness without compromising the other parts of the injection - which is the first (and only) rule when introducing new features into this library. As I said, PRs (preferably with proper research/tests) are welcome. Thanks! |
|
@barjin I think you have to be more specific here. I could indeed drop a PR for the repo but "would include hiding the headlessness without compromising the other parts of the injection" does not give much to work with. How would you define compromise? And also if you could give a tip of what code you advise be even better :) |
Describe the bug
Simply injecting fingerprint-suite (using
newInjectedContextornewInjectedPage), with or without options, for headless or headfull browser, makes the browser detected as headless in : https://arh.antoinevastel.com/bots/areyouheadless.Every time fingerprint suite is used, even without any option, it makes the browser detectable.
To Reproduce
Expected behavior
Injecting the fingerprint-suite shouldn't make the browser be detected as headless.
