Malware Attack on Vendor To Blame for Delta and Sears Data Breach Affecting ‘Hundreds of Thousands’ of Customers (

Delta Air Lines and Sears Holding on Thursday disclosed a data breach that may have exposed the payment card details of hundreds of thousands of online customers. From a report: The breach originated at a software vendor called [24]7, which provides Sears, Delta, and other businesses with online chat services. Less than 100,000 Sears customers were supposedly impacted, according to Sears. A Delta spokesperson said hundreds of thousands of travelers are potentially exposed. Gizmodo has learned the breach was the result of a malware attack, and that the unauthorized access involved payment card numbers, CVV numbers, and expiration dates, in addition to customers’ names and addresses.

In a statement, [24]7 said the breach occurred on September 27th of last year and was contained roughly two weeks later. In a statement, Sears said it was first notified about the breach in mid-March. Credit card companies have been notified, and law enforcement is likewise investigating the incident. “Customers using a Sears-branded credit card were not impacted,” Sears said. “In addition, there is no evidence that our stores were compromised or that any internal Sears systems were accessed by those responsible.”
