Only the top software engineers of the global captcha security firms have access to the source code, and then only when each one of them provides half of the security key to decode the system. The code is never actually loaded in memory. If this code ever got into the wrong hands then the entire captcha security system would be broken.Any ideas , guesses !!Maybe do a dictionary attack.Just mail around !!
