OREM, Utah, March 24, 2015 /PRNewswire/ -- Businesses continue to struggle with the prohibited storage of unencrypted customer payment data. In its fourth study on unencrypted card data, SecurityMetrics' patented card discovery tool PANscan® found that 61% of businesses store the unencrypted 16-digit sequence on the front of credit cards, also known as the Primary Account Number (PAN).
In the recently released Payment Card Industry Data Security Standard 3.0 (PCI DSS), merchants are instructed that, "Protection methods such as encryption, truncation, masking, and hashing are critical components of cardholder data protection" in PCI DSS Requirement 3.
However, in just five years PANscan has found more than 1.2 billion unencrypted card numbers on business networks.
"Unencrypted storage continues to be an issue among merchants, even with new technologies like EMV," said Gary Glover, Director of Security Assessment at SecurityMetrics. "EMV-enabled payment terminals can still be used to make a payment transaction using an optional mag stripe swipe process, which means there's still an opportunity for misconfigured software to inadvertently capture and store full track data."
The study revealed that PANscan scanned 204,332 GB of data on 3,627 computers and found:
A total of 332,263,315 unencrypted payment cards
61% of businesses store unencrypted PAN data, a decrease of 2% since 2014's study
7% of businesses store full magnetic stripe data, including PIN, CVV, service code, expiration date, cardholder name, and PAN
An average of 91,608 payment cards per computer
"I expect the trend of unencrypted card data storage to steadily but slowly decline each year," said Glover. "The sooner businesses implement point-of-sale encryption technology like P2PE (encrypt at swipe), the sooner stored unencrypted data will become a thing of the past."
