After one year of multiple high-profile data breaches targeting point of sale (POS) software used by retailers, millions of customers were at risk of potential credit card fraud. However, the retailers and banks also have endured a heavy financial burden, and this Christmas shopping season could bring a new round of cyber breaches, security experts warned.
"The threat actors are going to be burning the midnight oil trying to get credit card data going into the holiday season," said Brian Foster, chief technology of the Damballa security firm. "Retailers need to be prepared and diligent in the fourth quarter."
Target suffered a breach that led to 40 million customers having their debit and credit card data stolen, only two days before Black Friday in 2013. The BackOff malware has successfully breached more than 1,000 businesses and retailers, the Department of Homeland Security noted.
