Watch out for e-commerce sites asking for personally identifying information

E-commerce sites only really need two main data points from you: 1) your payment information, like a credit card number and 2) your shipping address. If they ask for anything else, consider finding an alternative. You don’t need to supply your Social Security number just to have a package shipped to your residence.

The e-commerce boom precipitated a new cybersecurity threat known as e-skimming, which involves the theft of consumer payment information from online stores. If you’re thinking about going online instead of the mall this year, it’ll be helpful to understand how e-skimming works and how to protect yourself against it.

E-skimming is the process of using malicious code to capture the sensitive credentials of a consumer, such as credit card information, from an online payment webpage.
