Hacking payment card "security codes"

This article suggests that the CVV code in the signature space of a payment card is "hackable" - which presumably means that their is a mathematical relationship between the card number and the CVV - which surprises one. http://blogs.zdnet.com/Howlett/?p=250 .probe

Is it so hard to make it random or unrelated to the car number? :S

I don't think that the two numbers are anyway related.

I think what they mean is the source (that one is to hack) that gives you the credit card number also gives you the CCV2 number.
