Otherwise, CAPTCHA comes at a cost to user experience (UX) and accessibility. The growing consensus is that web designers need to provide the right kind of CAPTCHA and use it only under specific circumstances. But CAPTCHAs (and the bots themselves) have become so sophisticated that the tests can end up stymying human users. When they’re properly employed, they’re a useful defense against spam and fake accounts. But if you’ve ever found yourself squinting over a CAPTCHA, trying to pick out photos of crosswalks, you know it’s not as easy as it sounds.ĬAPTCHAs are designed to guard websites against harmful bots. We also recommend to check cfresearch repo where Steven scaredos publishes his research on CloudFlare's protection.“I’m not a robot” seems like it should be the easiest thing in the world to prove.
CAPTCHA SOFTWARE 2017 CODE
Then call the callback found passing the token as the only argument.Īnother approach is to completely deobfuscate the callback code to understand what data the code consume and use to generate the data used in the request to /cdn-cgi/challenge-platform/h/b/flow/ov1/. Parse the arguments inside your function to get the callback definition from data-callback inside params. Store the original render function inside a variable, then use your own function that will catch both arguments container and params and return the original render method. Our opinion: the most effificient way is to use javascript injection to redefine hcaptcha.render(container, params) method.

We can solve the captcha and provide you a valid token, the rest of the job must be done on your side. Unfortunately no, we can not do all these actions on our side. Can 2Captcha do all this complex things for me? The code is obfuscated, but you can set some breakpoints and define some watch expressions to make things more clear. Now you can use callback function name in the javascript console to jump to the function definition and explore the code. Inspect this element, it will have some attributes including data-callback which will contain the callback function copy. Just get the extension and enable it, then open a webpage where you want to bypass hCaptcha challenge and search for captcha-widget element. Our 2Captcha Solver extension for Google Chrome can help you to see the callback function code.

To do so you have to understand how the token is encrypted by the javascript code. Is there an easy way to bypass hCaptcha on Cloudflare-protected page? You can try to use it to make sure it works in your case.

Our 2Captcha Solver extension for Google Chrome does this automatically. Can I bypass hCaptcha on Cloudflare-protected page with 2Captcha API? The callback function uses some additional data defined inside the javascript and applies some logic to encrypt the token and additional data before submitting it to the back-end on /cdn-cgi/challenge-platform/h/b/flow/ov1/. The callback is defined inside obfuscated javascript code loaded from /cdn-cgi/challenge-platform/h/b/orchestrate/captcha/v1. When you bypass the hCaptcha challenge the token is passed to a callback function. Now tokens are encrypted with the javascript callback function before sending. Now tokens are not sent as plain text inside HTTP request to the back-end as it was before. Recently Cloudflare changed the way of processing hCpatcha tokens after solving the captcha.
