Email Scam Uncovered Involving DRIDEX Malware

A new DRIDEX email scam campaign has been identified that has resulted in an angry response from Swedish furniture retailer Ikea. The hackers to blame for the malware have targeted Ikea customers by sending fake emails asking them to open a DRIDEX-infected email attachment. It is thought that hundreds of thousands of emails have been sent in the past few days.

As is usually the case with spam emails, users are not specifically targeted. The hacker rely on volume for success. This is why targeting a retailer the size of Ikea is particularly desirable. The potential for an email landing in the inbox of a customer is relatively high in Europe.

What is most worrying about this campaign is the fact the emails look authentic. They include an attachment which appears to be a purchase receipt issued  by IKEA. The receipt looks identical to one supplied by the store.

IKEA is worried that the spam emails will impact the company’s reputation, even though there is nothing the company could have done to stop the campaign. The guidance provided is not to click on any attachments in emails that appear to have been sent by the furniture retailer.
