Defeating Captcha

Posted by CmdrTaco on from the security-through-irritation dept.

An anonymous reader pointed us at PWNtcha, a package that breaks various on-line captcha algorithms. The site provides numerous examples of easy (Paypal, and an older version of Slashdot make the list) and hard Captcha. It also links various sources explaining why Captcha is a bad idea.

    1, 3, 5, 7, ...?

    9 or 11, depending on if you are expecting odds or primes. you should really have another number in the sequence to clarify that.
