Okemo Mountain Resort has been the target of a security breach that may have compromised tens of thousands of credit cards.
The ski resort says that hackers broke into its computer network and potentially gained access to credit card data from 28,168 transactions between February 7 and February 22 and 18,401 credit cards between January and March 2006.
The number of affected cardholders is unknown but Okemo expects it to be lower than the number of transactions.
Okemo is working to protect any personal information transmitted through its system from further unauthorized access. The resort has alerted credit card companies, which are notifying affected cardholders.
