“CAPTCHAs” Not an Obstacle for Criminals

by Dave on December 23, 2010

captchaYou’ve seen CAPTCHAs on various registration pages. Like the one on the right, it’s a test to see if its user is a human or a computer. CAPTCHAs are used by many websites to prevent abuse from “bots,” or automated programs usually written to generate spam. As a rule, computer programs can’t read distorted text as well as humans, so CAPTCHs are used to protect websites from automated spam programs.

At least that’s the theory.

According to Brian Krebs however, CAPTCHAs aren’t much of an obstacle for criminals. There are now services that use both automation and people to get around them.

CAPTCHA-solving services such as decaptcher.com, beatcaptchas.com and captchabot.com rely first on automation. If automation fails, the CAPTCHA is passed to workers paid ‘fractions of a penny’ to solve them.
