As of Friday afternoon, September 5th, we identified that our Visa Check/Debit card is under what is called a BIN attack. This is a brute force effort to send through thousands of transactions where the fraudsters randomly generate debit card numbers and expiration dates.
BIN attacks have become more frequent over the last year. Banks, Credit Unions and other card issuers have all been targeted.
The fraudsters have not obtained anyone's card information. They are guessing this information.
The Credit Union's card monitoring systems are blocking just about all of these fraudulent transactions. A VERY LIMITED number of card holders' card numbers were successfully guessed by the fraudsters, so we have placed a temporary freeze on those cards. Remember that no cards have been successfully accessed. Your accounts are safe.
We will have additional information available on this by Monday.
We appreciate your patience and understanding.
