Jhezza has just arrived at her office and she is checking her stock portfolio as she does every day. She connects to her broker web site and decides to buy some stocks that are highly recommended. She makes use of her special Portfolio Credit Card because she wishes to collect travel points. This is the only online site where Jhezza uses this specific card. Jhezza always ensures there is a secure connection established by looking at the lock icon at the bottom of her browser window. A few weeks later, Jhezza realized that someone has compromised her credit card number and has been doing fraudulent transactions online, the first of which is on the same day she used it to buy stocks from her office. How did the card number get compromised?
