Online retailer Play.com has e-mailed customers warning of a security breach that could compromise personal details.
The e-mail says: "We are e-mailing all our customers to let you know that a company that handles part of our marketing communications has had a security breach. Unfortunately this has meant that some customer names and e-mail addresses may have been compromised."
Play.com urged its customers to be vigilant with their e-mail and personal information when using the internet. "At Play.com we will never ask you for information such as passwords, bank account details or credit card numbers. If you receive anything suspicious in your e-mail, please do not click on any links and forward the e-mail to firstname.lastname@example.org for us to investigate."
The Payment Card Industry Data Security Standard (PCI DSS) specifies a level of security that companies taking credit card payments must adhere to.
