TMCNet:  Cyber Thieves Target Tesco Clubcard Vouchers

Cyber Thieves Target Tesco Clubcard Vouchers

(Sky News (UK) Via Acquire Media NewsEdge) The deactivation comes after thousands of usernames and passwords - taken from non-Tesco websites - appeared on a text-sharing portal.

It is believed that cyber thieves then used that data to crack accounts at Tesco.com, relying on the habit of some people using the same usernames and passwords for various websites.

A Tesco spokesperson told Sky News: "We take the security of our customers' data extremely seriously and are urgently investigating these claims.

"We are contacting all customers who may have been affected and are committed to ensuring that none of them miss out as a result of this." The speculative attack on Tesco was also used to steal Clubcard points from some customers - believed to number fewer than 10.


The company, Britain's biggest supermarket group, said it would reimburse those hit in the breach.

The spokesperson added: "We will issue replacement vouchers to the very small number who are affected." In early 2013 a number of Clubcard holders had their vouchers stolen by cyber criminals after Tesco spotted "irregular activity".

Log-in credentials of customers were allegedly harvested by hackers using phishing emails.
