Multiple financial institutions say they are seeing a pattern of fraud that indicates an online credit card breach has hit Park-n-Fly, an Atlanta-based offsite airport parking service that allows customers to reserve spots in advance of travel via an Internet-based reservation system. The security incident, if confirmed, would be the latest in a string of card breaches involving compromised payment systems at parking services nationwide.
Update, Jan. 14, 2015: Park ‘N Fly has acknowledged a breach. See this story for more details.
In response to questions from KrebsOnSecurity, Park-n-Fly said it recently engaged multiple outside security firms to investigate breach claims made by financial institutions, but so far has been unable to find a breach of its systems.
“We have been unable to find any specific issues related to the cards or transactions reported to us and by the financial institutions,” wrote Michael Robinson, the company’s senior director of information technology, said in an emailed statement. “While this kind of incident is rare for us based on our thousands of daily transactions, we do take every instance very seriously. Like any reputable company involved in e-commerce today we recognize that we must be constantly vigilant and research every claim to root out any vulnerabilities or potential gaps.”
Park-n-Fly’s statement continues:
“While we believe that our systems are very secure, including SLL encryption, we have recently engaged multiple outside security firms to identify and resolve any possible gaps in our systems and as always will take any action indicated. We have made all necessary precautionary upgrades and we just upgraded on 12/9 to the latest EV SSL certificate from Entrust, one of the leading certificate issuers in the industry.”
Nevertheless, two different banks shared information with KrebsOnSecurity that suggests Park-n-Fly — or some component of its online card processing system — has indeed experienced a breach. Both banks saw fraud on a significant number of customer cards that previously — and quite recently — had been used online to make reservations at a number of more than 50 Park-n-Fly locations nationwide.
Unlike card data stolen from main street retailers, which can be encoded onto new plastic and used to buy stolen goods in physical retail stores — cards stolen from online transactions can only be used by thieves for fraudulent online purchases. However, most online carding shops that sell stolen card data in underground stores market both types of cards, known in thief-speak as “dumps” and “CVVs,” respectively.
The CVVs stolen that bank sources traced back to Park-and-Fly are among thousands currently for sale in four large batches of card data (dubbed “Decurion”) being peddled at Rescator[dot]cm, the same crime shop that first moved cards stolen in the retail breaches at Home Depot and Target. The card data ranges in price from $6 to $9 per card, and include the card number, expiration date, 3-digit card verification code, as well as the cardholder’s name, address and phone number.
Last month, SP Plus — a Chicago-based parking facility provider — said payment systems at 17 parking garages in Chicago, Philadelphia and Seattle that were hacked to capture credit card data after thieves installed malware to access credit card data from a remote location. Card data stolen from those SP+ locations ended up for sale on a competing cybercrime store called Goodshop.
In Missouri, the St. Louis Parking Company recently disclosed that it learned of breach involving card data stolen from its Union Station Parking facility between Oct. 6, 2014 and Oct. 31, 2014.
