A spreadsheet with the names and addresses of thousands of customers and a link to download 7,941 vouchers was reportedly emailed to more than 1000 people.

All of whom were emailed the link could access the gift card codes and begin using the money to shop, reports Fairfax media.

The data breach was discovered on Saturday morning after customers logged on to find that their vouchers were already spent.


The vouchers had been purchased from Groupon which ran a deal offering Big W egift cards valued between $100 and $200 at a 7.5 per cent discount.

Customers impacted by the leak were emailed on Saturday morning informing them that the gift cards had been cancelled.

When contacted by Yahoo7 a Woolworths spokesman confirmed no personal data had been leaked, apart from the email addresses.

Woolworths would not reveal how many people had been impacted by the leak or how it happened but said they were investigating.

A spokesman added: “Woolworths takes the concerns of its customers and data security seriously.

“We experienced a technical fault with an e-voucher offered to customers this week. 

“We are working to resolve the issue and are assisting customers."
