A malware-infected email claims that several major supermarkets – Tesco, Morrisons, Sainsbury's and ASDA – have collaborated to offer customers an all-in-one shopping voucher. According to the email, the voucher entitles the bearer to receive £30 worth of spending for just £15. However, the message is not a legitimate offer and there is no such voucher associated with the supermarket chains.
Recipients are instructed to click a link in the email to obtain more information and download the voucher for printing. A second link in the message supposedly allows recipients to opt out of receiving further such marketing emails. Clicking on either link will reveal that a .zip file is downloaded on to your computer. The zip file contains an .exe file that, if opened, will install a Trojan onto your machine.
The text of the email is as follows:
