This is a Chrome Extension to automate the collection of gCaptchaCode strings. This should be used by developers that know how to make requests using cURL and where to use the gCaptchaCode.
This is NOT:
- ReCaptcha auto-click (it will not auto click in the checkbox when navigating in normal websites).
- ReCaptcha challenge solver (it will not solve the challenge when requested).
You can find it in Chrome Web Store.
- Automator (request every X minutes).
- CAPTCHAs URLs in page ContextMenus (right click).
- Copy gCaptchaCode to clipboard.
- Alert Human to solve the challenge.
- Statistics about captchas solved / not solved.
On some versions of Google Chrome (mainly 67), the onEvent function stops receiving requests for no reason. This hurts the behaviour of the extension, because no longer catch the userverify or payload endpoints of ReCaptcha.
This is currently solved.
Without the new code, a new versions is needed in order to work like Google Chrome Canary, unfortunately not available for Linux. For Linux you can try to check Chromium.
For better stealth, the hosts file of the computer that is running this extension can be modified to point to localhost. This will not impact extraction for gCaptchaCode, and improve stealth.
Location for:

c:\Windows\System32\Drivers\etc\hosts - Linux/OSX:

This extension automates a series of functions on the Chrome browser to extract gCaptchaCode. By installing this extension in several computers, gCaptchaCodes can harvest from different computers (like a botnet, but please use with the Human consent).
This will try to solve the ReCaptcha, replacing the HTML in the page by just minimum necessary scripts and request to solve the captcha. All connections will be blocked, except for Google ReCaptcha and the first request to the site that implement ReCaptcha.
This is a string with different sizes (442 or 485 characters, but might be other lengths), starting with (03ACgFB9, 03AEMEkE). This string can sent to the website that implement Google ReCaptcha to access the content protected by it.
It expires in 120 seconds, so be aware that to use it as soon as possible.
This extension have an options page where some behaviour can be adjusted.
If an interface is developed to insert gCaptchaCode, this extension ca be used to solve the captcha and automatically extract gCaptchaCode to Human clipboard. This functionality probably can extend (with this source code) to improve the automated behaviour.
When the Human request to solve a ReCaptcha, a new tab opens with the website URL in order to extract the gCaptchaCode. This new tab can be an active tab or a background tab. Don't know why, but normally code run on the background tabs takes longer to solve (~50 seconds vs ~7 seconds).
When ReCaptcha isn't automatically solved, it will ask Human to solve it (if this options is enabled). After it is solved, it will continue with the normal behaviour.
If this option isn't enable, it will close the new tab. When Human ask again the challenge can reappear or not.
If an interface is developed for the Human to insert gCaptchaCode, on Human action and if copy to clipboard is enabled, the gCaptchaCode will not be sent to the sinkhole. The user can use this interface to send it, mainly if the Human want to control some options to request.
If enabled, the Human will not have control over gCaptchaCode.
Captcha URLs is a list of websites to obtain gCaptchaCode. The information need for this setup is the main website URL (https://www.example.com) and the site key code available on ReCaptcha code in HTML.
Sinkholes are endpoints that are created to receive gCaptchaCode and use it. For each captcha URL request and solved, it will send for all sinkholes defined here.
When enabled, it will open a new tab (on background), load the ReCaptcha script, click in it, harvest gCaptchaCode and send to the sinkholes defined.
The frequency that this will be done can be defined, but is recommended to be above 100 minutes.
