I created a updated version of uncaptcha2 that works again in 2021 #15
Comments
Thanks for sharing! I've been following some of the updates Google's been making, and it doesn't seem like they've made any big changes. I was briefly in contact with them, and they let me know that they're more interested in their rate limiting that detects if you're sending automated queries. As far as I can tell, it seems to just check how many audio captchas you're doing in a short amount of time, so I'm not sure it's even possible to bypass, but I'd love to hear thoughts! |
Hi Nikolai -
Thanks so much for reaching out - this is awesome! It's so cool to see the community keeping uncaptcha alive. It's amazing to me that in 2021 this attack vector still exists - great work on this!
Best,
Kevin

Hi guys,
Thanks for the awesome work.
I think it is extremely funny that it is possible to solve Goolge's ReCaptcha with their own Speech-to-text API.
So I updated your code base and made it working again. See the repository: https://github.com/NikolaiT/uncaptcha3
Biggest change: Google removed the audio download link. I obtain the audio mp3 download link now via the Dev Console. Another possibility would be too start the browser with remote debugging enabled and to grab the download link with puppeteer.
Best,
Nikolai

Thanks for replying! I remember when I first saw this repository in 2019, I thought "no way that works". After trying it out for myself, I couldn't believe that it works so well after three years of its inception. After a while, Google blocks you based on one of (or combination of):
BUT: The Audio reCAPTCHA itself is completely, utterly broken. The normal, visual reCAPTCHA still works more or less. But it's a matter of time I guess. My estimation is: In 2021 and the near future, there is no other way to tell humans apart from bots than to:
Kinda interesting times. |
In 2022, we can insert a mouse track based on the Bessel curve in some visual challenges. Any operation is done based on |

Ahh yeah, and I randomized the mouse movements a bit and created random intermediate mouse movements before going to the destination.
