IDG News Service - Credit card transactions in the U.S. are often not encrypted, and credit card vendors, payment processors and retailers need to embrace an encryption standard to protect credit card numbers, the CEO of a breached payment processor said Monday.
Credit card numbers are not now required in payment card industry guidelines to be encrypted in transit between retailers, payment processors and card issuers, Robert Carr, chairman and CEO of Heartland Payment Systems, told a U.S. Senate committee. Heartland in January announced the discovery of a data breach that left tens of millions of credit card numbers exposed to a gang of hackers.
"I now know that this industry needs to, and can, do more to better protect it against the ever-more-sophisticated methods used by these cybercriminals," Carr told the Senate Homeland Security and Governmental Affairs Committee. "I believe it is critical to implement new technology, not just at Heartland, but industrywide." The purpose of the committee hearing was, in part, to determine whether new legislation is needed to fight cybercrime.
Heartland is pushing for the credit card industry to adopt an end-to-end encryption standard, he said, and the company is deploying tamper-resistant point-of-sale terminals at its member retailers. "Our goal is to completely remove payment account numbers of credit and debit cards and magnetic-stripe data so they are never accessible in a useable format in the merchant or processor systems," Carr said.
Heartland has asked credit card companies to accept encrypted transactions and the company has engaged standards bodies and encryption vendors, Carr said. The company has also helped to form an information-sharing council for payment processors, where the companies can share information about threats, vulnerabilities and best practices, he said.
"We are working on these solutions, both technological and cooperative, because I don't want anyone else in our industry, or our customers, or their customers ... to fall victim to these cybercriminals," he said.
Carr didn't give details about the Heartland breach, in which the company was compromised for about a year-and-a-half. The company remains involved in investigations and lawsuits involving the breach, he said.
However, Heartland paid about $32 million in the first half of 2009 for forensic investigations, legal work and other charges related to the breach, he said.
Senators asked Carr some pointed questions about the breach. Sen. Susan Collins, a Maine Republican, wanted to know how the company could be compromised from October 2006 to May 2008 without discovering the breach. "I was astounded at what a long period elapsed where these hackers were able to steal these credit card numbers," she said. "Explain to me how a breach of that magnitude could go undetected for so long."
