According to a report on expatica.com, the unnamed Dutchman ruined two perfectly good Campina tinned puddings with mouse poison. He then wrote to Campina to inform the dairy company that the venomous treats had been placed in a supermarket. He did this too late to prevent one of them being purchased and devoured. The victim fell ill, but fortunately has since recovered.
The European Digital Rights (EDRI) organisation reports that Campina was told to open a bank account with €200,000. Campina was then to send the blackmailer the information contained in the magnetic strip of the account's bankcard, together with the PIN.
The crook told Campina to hide this information using steganography – a technique whereby data can be encrypted and hidden within other electronic files, such as images or music. He sent the software that Campina would need to encrypt the data and instructed the dairy to place a fake ad for a red Volkswagon Golf on a car auction web site for the blackmailer to access.
Seeking to conceal his identity when visiting the car ad, the blackmailer used an anonymiser called surfola.com.
The Florida-based service allows e-mails to be sent and postings to news groups to be made anonymously. Its site reassures users, "We will not give out your name, residence address, or e-mail address to any third parties without your permission, for any reason, at any time, ever."
However, as EDRI explains, when the FBI came calling, surfola.com spilled the beans.
So the Dutch pudding poisoner was caught when trying to withdraw cash from an ATM. EDRI reports that he immediately confessed.
