Play.com, the biggest e-commerce sites in the UK, announced some of their customers may have had their personal details leaked online by a third party marketing firm.
Now it has emerged that the names and email addresses of a currently unknown number of users were stolen and subsequently used as targets for spam campaigns.
Play.com was apparently only made aware of the leak by the customers themselves, who noticed that they had started getting spam emails sent to accounts which were only linked to their Play.com purchases.
John Perkins, chief executive of Play.com, confirmed the only data to have leaked related to email addresses.
Play.com customers who were affected are advised to change the passwords on their email accounts as a precaution to ensure total safety.
