Police arrested Bruce Mengler of Solana Beach, California last week after a federal court issued an arrest warrant on federal charges of computer intrusion and extortion.
According to the San Diego Union-Tribune, Mengler compromised the web site of Maserati North America in March and obtained a list of customer details which the company had kept as part of a promotion.
The list reportedly included a number of individuals who had been asked to participate in a test drive program in exchange for gift certificates at a local steakhouse.
Upon accessing the promotional list, Mengler reportedly e-mailed Maserati with a sampling of several customer details and threatened to disclose the entire list publically if Maserati did not agree to pay him.
By the time Mengler was caught, the man had reportedly extorted some US$5,000 from the automaker.
Security experts say that the case underscores the need for companies to secure all customer data, whether actual customer information or just promotional lists.
"If a hacker was able to gain access to customer information via the promotional website then there is a clear warning here to all companies that they need to properly secure their public websites," wrote Sophos senior technology consultant Graham Cluley.
"It’s all very well asking for potential customers to enter their names and addresses in exchange for free steaks, but you’ll be dealing with higher stakes if your website is not properly defended."
