>So far I have only found one English item in the news about this.
>So let me translate some of the dutch information about this
>interesting case :
>A 45-year old chip designer from Utrecht was arrested June 3.
>He confessed to have tried to blackmail the 'Campina' food company.
>He had threatened to poison their products, and demanded 200.000 euro.
>The most remarkable thing about this case is however how he

>the 'world card' using a card-writer and a blank card.
>To send him the information, he made them use steganography!
>Campina received an envelope via snailmail containing a floppy with a
