Australian grocery chain Woolworths had to cancel over $1 million in gift cards when an employee accidentally emailed an Excel spreadsheet with customer information and redeemable codes for over 1,000 giftcards. The breach occurred on the heels of a Groupon sale of $100 and $200 gift cards at a small discount. Privacy Rights Clearinghouse reported that last year more than 113 incidents involved accidental leakages, involving more than 440,000 records. Verizon says 90 percent of breach cases the firm investigated had some component of employee involvement.”]
