This problem was solved long ago to the apparent satisfaction of the marketplace: <a href="http:&#x2F;&#x2F;bypasscaptcha.com" rel="nofollow">http:&#x2F;&#x2F;bypasscaptcha.com</a><p>George, the devil is in the details. You can&#x27;t do everything overnight.<p>0% chance of success.

&gt;the Google Self Driving Car Cheaters<p>How is the Google self-driving car team cheating?<p>Or is he just being a sore loser about how his own self-driving car venture didn&#x27;t work out?

Why only street signs though? The new captchas I&#x27;ve seen ask you all sorts of random image recognition things, like identifying the squares with grass, with tea, with eggs, etc.

Current solutions on the market solve new google recaptcha with up to 50% accuracy. Let&#x27;s see what Geohot can do.

Has he read this paper? <a href="https:&#x2F;&#x2F;www.blackhat.com&#x2F;docs&#x2F;asia-16&#x2F;materials&#x2F;asia-16-Sivakorn-Im-Not-a-Human-Breaking-the-Google-reCAPTCHA-wp.pdf" rel="nofollow">https:&#x2F;&#x2F;www.blackhat.com&#x2F;docs&#x2F;asia-16&#x2F;materials&#x2F;asia-16-Siva...</a>

Clever idea, but Google also has some bot (and maybe also captcha farm) detections to try to ban captcha gamers. I think you&#x27;d also need a distributed and human-seeming proxy network.

Wonder if anybody commenting has read the readme. This is just a learning experiment.<p>Is it really wrong for a famous hacker to dip his toes in a new language by doing something that is not state of the art?

He was the biggest hacker, tried to be an entrepreneur, now he is working hard to became the biggest comedian of Silicon Valley. Seems like the comedian role might actually work out.

Here&#x27;s my solution: rerecaptcha.<p>1) Own or work with a very popular site with people filling captchas often<p>2) Instead of showing a full random captcha, use the recaptcha technique against itself: show a small random captcha alongside a full recaptcha that you want to break<p>3) Use the random known captcha for validation and profit from the user entered recaptcha

You have to admire the showmanship: using a language Google created to try and break a Google-made system.

... this code literally just scrapes images from recaptcha right now, and it barely does that.<p>If you want it broken, all you have to do is take these images and feed them through a captcha cracking service that uses humans and get them to input numbers for the corresponding squares. Works fairly well in my experience. And $1&#x2F;1k you can&#x27;t argue with.

Geohot never stops to amaze me, at least.
