Yahoo! CAPTCHA Cracked

Thursday, January 31st, 2008

What a coincidence: 2 posts in a row on Yahoo!

It was just a matter of time. It is just impossible to automatically create a CAPTCHA that can not be beaten by another algorithm.

See the claim by these ’security researchers from Russia’ online. Anyhow CAPTCHA can easily be cicumvented by the so-called “relay attack,” where you’re relaying the CAPTCHA through a site where you’ve got enough traffic in order to generate a useful number of CAPTCHA solution events on the fly.

Instead of being tricked into the cat and mouse game, alternatives should be considered. Try scenarios without a CAPTCHA, or consider using reCAPTCHA

“About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that’s not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into ‘reading’ books.”

Yahoo Implements OpenID

Saturday, January 26th, 2008

Yahoo announced they will support and integrate OpenID. This is a big push forward for the OpenID project.

OpenID eliminates the need for multiple usernames across different websites, simplifying the online experience. Not only does it make life easier, it does increase overall authentication security for the involved web applications.

Let’s hope the other big online players do also include this. To get started using an OpenID, get one at e.g. myopenid. Once you have an OpenID, you can use it at a number of sites.

I you have a blogger account, it can also use your blog’s URL as an OpenID URL.

It’s dead easy: I just created my OpenID URL at Verisign and published my details to the OpenIDDirectory. I did the latter already signing in with Verisign’s OpenID :-).
