TOPICS: Security

Customers of have been left open to spam fraud after one of the online retailer's suppliers suffered a data breach. wrote to users on Monday outlining the problem, which it said may have exposed email addresses, but not credit card details.

It seems there is cause for concern. We will be establishing from [] what has happened and how we can deal with it.

– Paul Vane, Office of the Data Protection Commissioner

"We are emailing all our customers to let you know that a company that handles part of our marketing communications has had a security breach," said the message. "Unfortunately this has meant that some customer names and email addresses may have been compromised."

The third-party company that suffered the leak is Silverpop, a spokeswoman for told ZDNet UK. The email database company saw a data compromise in December 2010 that affected McDonald's customers.

Silverpop told ZDNet UK on Tuesday that it had suffered a breach in the autumn of 2010, but did not believe that this was affecting customers.

"While we are reviewing all possibilities, it's difficult for us to directly connect the 2010 incident with specific spam messages sent this year," said Silverpop spokeswoman Stacy Kirk. is a major UK online seller of games, DVDs and other products. However, it is based in Jersey and is now being probed by the island's privacy authority, the Office of the Data Protection Commissioner (ODPC), over the breach.

"We've been made aware of [a possible breach] in the last half hour," deputy commissioner Paul Vane told ZDNet UK on Tuesday. "It seems there is cause for concern. We will be establishing from [] what has happened and how we can deal with it."

Vane said a UK-based customer had forwarded a forum post with concerns about a possible leak, plus the warning email from the company. As is ultimately responsible for its customer data, Vane said the ODPC would expect to see a robust data-processing contract between and the marketing agency that had the security breach.

"If a breach is identified, we can issue an enforcement notice or an undertaking... This is a strategy we use as a last resort," said Vane. "There is a possibility enforcement action could be used."

  • Hello Redbluered,

    There is some more info. sent out an email to customers this morning, still saying it believes that customer email addresses were compromised in the Silverpop breach:

    "Dear Customer,
    As a follow up to the email we sent you last night, I would like to give you some further details. On Sunday the 20th of March some customers reported receiving a spam email to email addresses they only use for We reacted immediately by informing all our customers of this potential security breach in order for them to take the necessary precautionary steps.
    We believe this issue may be related to some irregular activity that was identified in December 2010 at our email service provider, Silverpop. Investigations at the time showed no evidence that any of our customer email addresses had been downloaded. We would like to assure all our customers that the only information communicated to our email service provider was email addresses. have taken all the necessary steps with Silverpop to ensure a security breach of this nature does not happen again.
    We would also like to reassure our customers that all other personal information (i.e. credit cards, addresses, passwords, etc.) are kept in the very secure environment. has one of the most stringent internal standards of e-commerce security in the industry. This is audited and tested several times a year by leading internet security companies to ensure this high level of security is maintained. On behalf of, I would like to once again apologise to our customers for any inconvenience due to a potential increase in spam that may be caused by this issue .
    Best regards,
    John Perkins

    Silverpop told ZDNet UK:

    "Silverpop was among several technology providers targeted as part of a broader cyber attack that occurred in the fall of 2010. At that time, we very quickly stopped the attack, notified all customers impacted by the activity and began working with the FBI, law enforcement and third party security experts to help identify those responsible and take any additional steps necessary to ensure this did not happen again. We are confident that the breach last year remains an isolated incident."


    "We cannot comment on specific customers nor are we privy to how any particular customer manages their data outside our system. While we are reviewing all possibilities, it's difficult for us to directly connect the 2010 incident with specific spam messages sent this year."
