A bot cracked Microsoft live captcha in just 6 seconds

I am sure most of you are aware of Captcha (Completely Automated Public Turing Test to Tell Computers and Humans Apart ) if not then CAPTCHA is the name given to the distorted, scrambled characters that many Web services require users to decipher and type in to create a new account; the tests are meant to block automated account registration by spammers and malware authors.You can find the world's most complex CAPTCHA here.

Here are the technical details of the Captcha that broke the Microsoft Live email id registration form.Actually this process enables the hacker to register as many as required email id's to send his/her spam within a very short time period.Most of the hackers prefer the Id's of Gmail, yahoo, and Msn because it is hard to mark Ids of these domains as Spam Ids by anitspam tools.

According to the experts,this Bot has relatively less response time compared to the old ones. Response time means how long it takes the program to grab a CAPTCHA image, analyze it and return with the correct code.

One in every eight to 10 attempts to create a Live Hotmail account is successful meaning that the success rate is 10% to 15%. However, the rate is actually meaningless, since the bot will continue to try to create accounts using a predetermined list of account names until they're all registered.This bot starts sending Spams from the registered IDs immediately.Now its up to Microsoft to detect this bot and remove all those email Id from their database.
