You can do everything right, but credit card fraud is inevitable.

In recent weeks, Cyber Protection Magazine has fielded calls and emails from people who have followed all the best-known techniques for securing banking, debit, and credit card information. That includes bank notifications every time the card is used, multi-factor authentication (MFA), biometrics, and limiting the use of a card for specific transactions. These readers still experienced unauthorized use of their payment cards

How does that happen?

The market for criminal use of legitimate credit cards is a well-known “secret.” The most common sites are found on the DarkWeb, but occasionally they pop up on Meta sites, where they can reap thousands of dollars before Meta gets around to kicking them off, generally without prosecution.

Enterprises selling the card information gather it by sending fraudulent emails or text messages, posing as legitimate entities, and tricking individuals into providing their credit card information. Then there is basic social engineering, manipulating victims into revealing their credit card information through phone calls, and QR codes.

While it may not be obvious that the skimmers have been added to the terminal, it is fairly easy to determine if it is legitimate. Legitimate card readers cannot be easily removed, while skimmers may be held on with a simple adhesive. Some locations, like Costco fueling stations, place tape over the reader and, if broken, can alert users and the vendor that there may have been a breach.

No one is completely safe

But by and large, data breaches are the most common source of stolen credit card information, and that is something most victims cannot do anything about.
