If you have ever used your physical card by swiping or using the chip, your data can be harvested. Your credit card number was skimmed or shimmed. Skimming is when you swipe your card and the magnetic data is captured by a device called a skimmer. Fraudulent actors then enter the data online or create a fraudulent card (fake) with your data. A shimmer is similar, but captures data off the chip.

Another popular way of harvesting credit/debit card data is a brute force BIN attack. Fraudulent actors gain access to a smaller business with weak security. They know the first 6 digits of the credit card is the Bank Identification Number (BIN) and put through tens of thousands of numbers and collect the hits that work. Then they use the numbers in a website and collect transaction data that work. This data can be sold on the dark web or used for fraudulent transactions at merchants.
