Posted By Eli On March 17, 2008 @ 11:03 pm In Random Thoughts, Check Mates | Comments Disabled

Guess what I’m in the mood to talk about? You guessed it. Captchas! In fact I feel like dedicating a whole week, maybe more depending on if any downtime occurs. :) to talking about nothing but captcha breaking. We’ll break every captcha in the book and even by the end of this post the captchas that haven’t been created yet. Furthermore, for this week only I am accepting any and all captcha related guest posts. So if you got a captcha solved or want to discuss techniques to breaking them feel free to write up a guest post and email it to ELI at BLUEHATSEO.COM in html form. You can stay anonymous and not only will I put it up but I’m also willing to put up any ad you’d like. Pick any text or banner ad you’d like to put up with your post and I’ll include it. With as many readers as this place has I’m sure it’ll get clicked. Also be sure to include your paypal address. If I really like your guest post I may even send you a $100 as a thank you. Also, all you bloggers are welcome to repost any of the captcha related posts on this blog. I now declare any captcha related posts on this blog public domain and republishable under full rights. For some odd reason I feel like blowing the captcha breaking industry the fuck up. Like my favorite saying goes, if you’re going to wreck a room you might as well WRECK it. Lets begin by visiting one of my first captcha related posts; the [1] Army Of Captcha Typers.

The Army of Captcha Typers is a great technique because it doesn’t require loads of programming and is 100% adaptable to any captcha. I suggest you go back and reread it, but in interest of keeping this short here’s a quick summary.

You use a service, I used a proxy site as an example, to get the users to type in the captchas for you. It records what the user typed in as the solution to the captcha and you use that to solve it. The more pageviews the service provides per user the more effective it is to breaking captchas. Why pay Indians or tediously code it yourself?

Normally I like to leave most of the code and creative portion out of the written technique in interest of not ruining the technique and to help the methods be more effective through use of spins and unique code. I don’t write this blog to ruin techniques, and those people who claim I do are just insecure and like to claim they already know everything. As common sense as most of the stuff I post is, I haven’t met a person yet who hasn’t in some way learned something from this blog. That truth brags a lot louder than most SEO blogs I’ve seen. But! If we’re going to wreck something lets wreck it. In that spirit I see no reason why every newbie on the planet shouldn’t be able to easily throw up their own web proxy site that solves captchas for them so here’s the script to do it.

[2] Captcha Solving Web Proxy

This a modified version of CGIPROXY that I mentioned in the post. Basically you install it following the included instructions (README file). Then you setup your web proxy site. Target a niche such as kids behind a school proxy or something similar. There is an extra file included called captcha.cgi. Upload it to the cgi-bin in the same folder as the nph-proxy.cgi and give it 755 chmod permissions. Make a folder one directory below your cgi-bin called captchas. Give it read/write permissions (777 should work all else fails). Then anytime you got a captcha to solve upload it to that directory with a unique filename. This can be done automatically with whatever script you’re using to spam a captcha protected site. On the very next pageview the webproxy will require the person to type in the captcha and disguise it as a human check to prevent abuse. Any captcha works. Once it gets their response it’ll delete the captcha from the folder and write out the solution along with the filename to a new file called solved.txt. Format: characters|image.jpg\n . Remember to make some kind of reminder or code for the filename so you know which image is which when you go to use the solutions. Get enough users to your webproxy (which is very easy) and you can solve any captcha in moments.

Enjoy!

Eli, Ive watched with great interest what has been happenning to this blog in the past couple of weeks whilst reading the eli working for whitehouse thread at wickedfire. I just want to say that the guy doing the dos attack must be iether a complete ass or very stupid, most probably both..

About the captchas, because i work mainly with php ive been looking at ways at breaking captchas using the gd library and/or image magik, although I havent really had any great results yet im getting there and hopefully i will send you the script to post when i can get it to a decent success rate, im on about 30% at the moment.

still looking forward to your seo empire part two post and dont let these dos attack asswipes grind you down

cheers

Mr. Eli

As I understand, you helped software terorists with attacks on the whitehouse.gov site.

Terorist and those people that help them can and will end up in Guantanamo Bay.

You have been warned!

#10 Comment By Papa Rage On March 18, 2008 @ 5:09 am

I don’t believe for a second that those ass hats attacking your site care about captchas.

But I personally find them interesting and I’m glad your back posting again.

#11 Comment By jboucinha On March 18, 2008 @ 6:30 am

Hey Eli, we have at least two more posts about captchas…
Can’t wait that long for the Seo Emp. p2 !!!!

#12 Comment By Paul D. On March 18, 2008 @ 6:49 am

Nice to see you back up Eli. I just hope the guy didn’t have a hard time breaking a captcha and decide “Screw breaking it myself, I’ll DDoS BlueHat and tell them it’s because they shared too many Captcha secrets. Then maybe he’ll get mad and break the captcha for me”. Not at all likely, but that’s the first thing that came to my mind after I read this. Either way, this should be an interesting week.

CAPTCHA is dead! is really easy to breaks now

#42 Comment By Photoshop Guy On July 30, 2008 @ 5:09 am

I would add one small thing to your post.

Don’t delete the captcha until you have 2 people who have typed in the same answer for that captcha. It would require a few more lines of code to do some comparisons in the database but the added accuracy is worth it.

#43 Comment By Eugene SEO Elite On August 21, 2008 @ 1:10 am

Thank you for taking the time and effort to discuss Captchas, informative article

I think the captcha questions are ok though.

Good work Eli! Kapcza DEAD!

#54 Comment By eBay Best Deals On December 7, 2008 @ 3:43 pm

Good Work. The Captcha is almost gone!

#55 Comment By Custom Software Development On December 26, 2008 @ 11:49 am

This is a pretty ingenious solution but it also requires time to code and it isn’t too fast if you intend to automate something on that website. As a developer I think it would be much easier to spend some time to just break the captchas. You don’t need a fancy algorithm. Neural networks is just fine and gives decent results even with a lot of garbage data around. After you have made your first captcha breaker you can reuse code and make a new one a any time. If you don’t know how to but have a noble purpose (aka educational purpose :) ) pay somebody in India or Eastern Europe to do it. It can be quite cheap in countries where developer wages are measured in hundreds of dollars not thousands :D

#56 Comment By Wordpress SEO On January 4, 2009 @ 1:10 pm

I love the idea of using a website like a proxy to get others to do the manual labor for you….

Just can’t think of any services that I cant use because of a captcha….

To commenter above: Don’t use this for evil. Easy as that.

#60 Comment By San Diego SEO On January 22, 2009 @ 10:39 am

I have seen a CAPTCHA with “count the number of ninjas in the image”. I love that. Anyone knows where to get that from?

#61 Comment By Busby SEO Test Newbie On January 26, 2009 @ 9:05 pm

which is better, captcha with counting number or captcha with image?

#62 Comment By Singapore Hotel On January 28, 2009 @ 9:42 am

Agree that captchas are a thing of the past.

#63 Comment By Sweaty Palms On January 29, 2009 @ 4:13 pm

This is pretty genius, I must say.

Captchas are my personal interest too and I have to admit there’s no way I’d thought of that myself.

#64 Comment By Rocket Spanish Review On February 1, 2009 @ 8:40 am

If captchas go, some thing else will come and replace it. And then that will be cracked and on and on and on!

#69 Comment By Alec M. Small On February 9, 2009 @ 4:59 am

I really don’t know alot about captcha, so I tried to read your post - and guess what, I still don’t understand anything about it. All I know is that thousands of people from the Philippines or India or other countries make a meager dollar to type in 10000 (am I right?). What’s that for?

And oh, is an audio version of a captcha called captcha too? Haha.

Great Post.

But Capcha is many blogs not dead.

#77 Comment By opt in email marketing On February 27, 2009 @ 3:36 am

I ask you all if this worth the effort. If the site makes money as well as solves captcha then I guess that’s cool, but otherwise it’s a lot of work on a long shot.

#78 Comment By Shop Fittings On March 3, 2009 @ 2:33 am

Captchas can only do so much. It helps though.

#79 Comment By Andrew Yu-Jen Wang On March 3, 2009 @ 6:30 pm

Speaking of George W. Bush:

George W. Bush committed hate crimes of epic proportions and with the stench of terrorism (indicated in my blog).

George W. Bush did in fact commit innumerable hate crimes.

And I do solemnly swear by Almighty God that George W. Bush committed other hate crimes of epic proportions and with the stench of terrorism which I am not at liberty to mention.

Many people know what Bush did.

And many people will know what Bush did—even to the end of the world.

Bush was absolute evil.

Bush is now like a fugitive from justice.

Bush is a psychological prisoner.

Bush has a lot to worry about.

Bush can technically be prosecuted for hate crimes at any time.

In any case, Bush will go down in history in infamy.

Your alternative to a captcha is terrible! Sorry but it really is. It usually takes me at least 2 tries to post a comment because I’m always told that i didn’t pass math!
What gives? 0 plus 9 is 9, why does it tell me it’s not?!
arrrghhh

#107 Comment By Wordpress Website guy On May 16, 2009 @ 8:20 am

Yeah, Captcha is very useful because no spambot can surpass it’s checks even if it’s adding numbers like here. Some black hat softwares won’t work when captcha is involved because they cannot pick it up. It’s a good way to fight spam. I like your offer but I don’t have any much knowledge about Captchas hehe.

i think the guys who make SBD have come up with some capture reading software… not sure if its actually released yet though. nor have i tried it would be interesting to see if it works though.

#147 Comment By go go hamsters On October 21, 2009 @ 7:41 am

im not so sure about this either.. having lots of high pr traget links might make a difference such as .edu and.gov but its not going to be easy!

Captchas are good thing against spamming but some times these are the headache for users when they continuously ask to the users.

#150 Comment By sticker printing On October 28, 2009 @ 8:51 am

Eli, you talked and discuss with detail about captchas, its really like a dreadful disease, especially when i cannot read it or the format is too weird to read it and user have to put the words again n again getting a same page asking to reenter the words. Ahhhh

I actually don’t use captchas any longer. Proxy detection and blacklisting is far more reliable.
