At 1st Cooperative Federal Credit Union, your safety and security come first. We understand that the words “credit card fraud” can spark concern, but it’s our responsibility to keep you well-informed and protected.
Recently, we’ve noticed a small number of our members have been targeted by what’s known as a BIN Attack. A BIN, or Bank Identification Number, refers to the first six numbers on your credit card. These unique numbers can be used by fraudsters to generate complete card numbers.
How does a BIN Attack work? It’s simpler than you might think. Fraudsters use software to automatically generate the remaining numbers after the BIN and test these combinations to see which card numbers are correct and if the cards are active. This is usually done by making small transactions through an online store.
These attacks can range from a few card numbers tested per day to potentially thousands in just a few hours. This does not mean anyone’s card numbers have been compromised. Instead, this is a strategy that fraudsters use to try and guess card numbers, akin to throwing a handful of darts and seeing what sticks.
Here are a few ways we can join forces to counteract these attacks:
Regularly monitor your credit card statements
With our online banking platform, you don’t need to wait for your monthly statement. Feel free to log in and review your transactions at any time. If something doesn’t seem right, notify our card services team by calling 1-855-504-3392. This number is listed on the back of your credit card.
Keep your contact information current
It’s essential that we can reach you quickly if card services detect any unusual activity on your account. Please ensure your contact information is up-to-date.
Exercise caution with unknown calls
Remember to exercise caution when sharing any information over the phone. If you receive a call from a toll-free number that you are not familiar with and are being asked to confirm transactions, it is important to trust your instincts. If you feel uneasy or uncertain about the call, it is best to end the conversation. To ensure the call is legitimate, you can independently contact card services at 1-855-504-3392 and verify the authenticity of the call.
Pay attention to small transactions
Small, unusual transactions—also known as micro-transactions—could be signs of an attack, since fraudsters often make small purchases to test whether a credit card is active. Report any small transactions to card services immediately by calling 1-855-504-3392.
