Reports via Slashdot here and here. The first one is probably a duplicate of an earlier story (this being Slashdot after all ...).

The second one is more interesting. The infamous spam software "XRumer" now comes with CAPTCHA breakers built-in (or rather, with more advanced ones, since it could do that for a while). Including, so they claim, the ability to break CAPTCHAs that are based purely on images ("spot the cat").

I think this quote from the discussion sums it up nicely:

Soon, the only thing that will be able to read a CAPTCHA will be automated spam bots. The new CAPTCHA test will be: "If you can read this CAPTCHA, you are a spammer."
