GROCERY giant Woolworths has scrambled to cancel over $1 million worth of shopping vouchers after a massive leak of customer data, in which it mistakenly emailed the redeemable codes of 8000 gift cards containing the customers' names and email addresses.

It is understood the spreadsheet was emailed to more than 1000 people, all of whom could access the gift card codes and immediately begin shopping.
As a result of the data leak, customers reported they had logged onto the Woolworths site on Saturday only to discover their vouchers had already been spent.
The data breach, which was discovered on Saturday morning, occured after customers purchased the vouchers from the online savings site Groupon, which ran a deal last week offering BIG W eGift cards, valued at $200 and $100, at a 7.5 per cent discount. The cards were redeemable at Woolworths online and in store, Big W stores, and Caltex petrol stations.
Once customers had paid for the vouchers via the Groupon site they were advised they would receive an email from Woolworths' Everyday Gift Cards containing a PDF attachment with the electronic voucher.
