Australia-based Woolworth mistakenly emailed an Excel spreadsheet unleashing a data breach of 8000 gift cards containing redeemable codes, and customers' names and email addresses. The total gift card worth came to AU$1,308,505.

Customers purchasing the vouchers on the bargain site Groupon discovered the virtual money had already spent by fast thinkers who had received the leaked email. The 7.5% sale on eGifts, valued at $200 and $100, were redeemable at Big W stores, Caltex fuel stations and at Woolworths.

While the data breach unlikely impacted any Americans, it was reminder of how information could fall into the wrong hands.
