ReCapcha isn't flawed like some of the other capcha systems out there. So you can't bypass it and you can't OCR it. Even if there was a way to bypass they would press the magic button and it would be fixed. Remember that reCapcha is a service focused purely on this.

The only known way to get around it is to download and solve millions of capcha's, have them solved via some online service, and store the ID + answer in a database.

If you can crack ReCaptcha you will get my company MafiaHost.

It seems kinda flawed, i was messing about with the demo on

http://www.google.com/recaptcha/learnmore

it would say like "it silkiest" and when i type "ir silkiest" it said "Correct!" i did this a few times e.g. "and seasick" typing "amd seesick" and it again told me it was correct... it may just have been the demo, not being a fully working demo or something but it does seem to be not completly perfect not sure if it was isolated incident but it did it a few times told me incorrect answers where correct....

Note: i do not condone spamming or mass account creation....

Thats because they have a voice system as well for those with bad eyesight.

Like Hyp said m8, you would have to download the entire DB and solve it.
Thats what these guys did: http://decaptcher.com/client/

You could implement their service and just tell the users that they are required to pay $2 per 1k sucessful decaptchas - as per website.

You cant just use a speech to text thing, and modify the code so it accepts input from the captcha?

[jayfella]

well you can try, but the speech is distorted and kinda hard to understand tbh.

i use decaptcher and deathbycaptcha services for all my bots. lol there were days when I would have used up over 50k captchas per day

jayfella you are wrong though.. they don't have the entire DB or any shit like that... some of the easier captcha system can be cracked, but most of the new CAPTCHAs and especially reCaptcha is uncrackable till now.

Both decaptcher and deathbycaptcha captcha solving is processed by humans... (or more likely indians who get paid to solve captchas all day long) and they support all types of captcha solving except ASSIRA captchas.

How would you know that they don't store answers and ID's? Fact is, not doing so would be dumb. Especially for reCapcha which relies on words of which it knows that they are hard/impossible to OCR.

[timtamboy63]

Yeah, but im assuming they use a lot less protection for the speech part of it, as if its too messed up people wouldn't be able to hear it too well.

I can't code, but i can't imagine that exploiting that feature to bypass it through a bot would be all that hard?
