Ransomware

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.

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
