CAPTCHA is Dead, Long Live CAPTCHA!

Interesting post on coding horror. 3 of the most well known CAPTCHA's are now broken - Google, Hotmail and Yahoo!

Wisdom comes from Gunter Ollman, he notes:

CAPTCHAs were a good idea, but frankly, in today's profit-motivated attack environment they have largely become irrelevant as a protection technology. Yes, the CAPTCHAs can be made stronger, but they are already too advanced for a large percentage of Internet users. Personally, I don't think it’s really worth strengthening the algorithms used to create more complex CAPTCHAs – instead, just deploy them as a small "speed-bump" to stop the script-kiddies and their unsophisticated automated attack tools. CAPTCHAs aren't the right tool for stopping today's commercially minded attackers.

As i read in an early post about it, I'm not sure that the captcha is a good defence against bots.

Do you like playing in the game which you need to use maple mesos, when you do not have mesos, you must borrow cheap mesos from friends, or you buy maplestory mesos. If you get maple story mesos, you can continue this game.
