MADISON, Wis. (9/15/11)--Two recent hacking incidents underscore the need for credit unions and their vacationing members to monitor their accounts for suspicious activity. Hackers accessed two computer stations owned by Vacationland Vendors of Wisconsin Dells, Wis., putting about 40,000 credit or debit card users at risk (WISCNEWS.com Sept. 14). The computers were at arcades in Wilderness Resorts in popular resort towns Lake Delton, Wis., and Sevierville, Tenn. The company owns and operates 11 arcades. “Based upon its investigation to date, Vacationland Vendors reasonably believes that a computer hacker improperly acquired credit card and debit information,” a message on Vacationland Vendors website states. “This incident did not involve an internal security issue within the Wilderness Resort. Vacationland Vendors has learned that other businesses just like its own have been affected by this computer hacker.” The company was alerted to the breach, which occurred March 22, as a result of calls from one or two customers, according to Evan Zeppos, a spokesman for Vacationland Vendors. Although 40,000 credit or debit card users’ data were stored on the terminals, fewer than 20 individuals were believed to be impacted, Zeppos said. The Vacationland Vendors website advised consumers who have used their credit card or debit card at the Wilderness Resort locations in Wisconsin or Tennessee from Dec. 12, 2008 through May 25, 2011 to watch for any unusual activity on statements or accounts or suspicious items on their bills. Card issuers should be informed of the incident and consumers should place a fraud alert on their consumer credit file, the website said.
