International Checkout, Inc. recently notified customers after a security breach involving a database containing credit card numbers.
The breach was discovered in mid-September, although the firm does not indicate how it first became aware of the problem. Subsequent investigation, completed on October 31, determined that the breach had occurred on August 23. Those affected were sent letters on or about November 23.
In its letter, the California-based firm notes that the data were encrypted, but suggests that customers check their card statements and discuss with their banks whether they should change their card number.
