I posted this article as a reply to an earlier post about CAPTCHA codes and how they keep out automated bots but I think this is still interesting:

It’s just more proof that the more we fight all the new malware and bots, they can always fight back. This time luckily it was from people who had no intention of doing anything bad with it (hopefully) but what if others had created that with the intention of maliciously attacking sites such as Ebay? This like this are how we stay ahead of the game. Whenever a new system to keep things out comes along, the first thing people need to do to make sure it works is to try as hard as they can to break it because there will most definitely be others trying.
