ReCAPTCHA.net Now Vulnerable to Algorithmic Attack

Posted by timothy on from the bless-you! dept.

n3ond4x writes "reCAPTCHA.net algorithms have been developed to solve the current CAPTCHA at an efficacy of 30%. The algorithms were disclosed at DEFCON 18 over the weekend and have since been made available online. Also available is a video demonstration of random reCAPTCHA.net CAPTCHAs being subjected to the algorithms." There's probably an excellent Firefox plugin to render this page's color scheme more bearable. Note: the PowerPoint presentation linked opens fine in OpenOffice, and the video speaks for itself.

      Did you not learn when I explained this yesterday? The quote is: "My eyes! The goggles do nothing!". There is no "they", nor is there any bad pronunciation. Indeed, it is correctly articulated and enunciated, with an accent.

      Easy there champ, nobody appreciates a Family Guy nerd correcting everyone's quotes.

      Judging from the other replies, meta-humor is a little hard for you guys...

      It works wonders though. For instance, the next time someone is talking about "the force" or jedis and such, tell them "Get a life, Star Trek sucks!". You'll find the reaction much more interesting than if you correctly identify the franchise.

    It looks like that tool is better at deciphering the captchas than I am.

    Should I run the DEFCON presenter's giant SWF or not?

      Why not. You run Firefox right? If yes then you have no worries because it's not full of hole like IE is...

    A Firefox extension is not the same thing as a plugin.

    Firefox plugins ***used*** to be called Firefox extensions. You must just be too young to know this.

    It's a bit like watching scary women fight over who was married to some guy first on Ricky Lake.

    You know a hacker is hard core when his site is monochrome in a monospace font, and he saves his files as straight up docx.

    You young ones and your complaining. "Ohhh the colors suck" SO WHAT! You don't remember when the Internet was invaded by those dual demons from hell, Geocities and Comet Cursors! Now THAT was torture buddy! YOU try dealing with a page that looks like it was designed by Unicorns on a crack binge, while having a fricking pocketwatch suddenly appear and hang from your cursor like a ball of snot on a string, all while having your shotgunned modems drug down to 300 baud land thanks to a bazillion puke inspiring GIFs spinning all out of time!

    Now THAT is real suffering kid! /wanders off muttering/

    They are not considerably lower because as book words are solved they become verification words. Also, if you didn't enjoy my talk, don't come next time.
