More than 100 e-commerce sites around the world are infected with malicious code designed to surreptitiously skim payment card data from visitors after they make purchases. Among those infected are US-based websites that sell dental equipment, baby merchandise, and mountain bikes.
There’s no easy way for people to know for sure if an e-commerce site they’re browsing is infected. Malwarebytes and many other endpoint security programs will block the best-known campaigns, but new ones pop up so often that these products can’t be expected to catch all of them. People should never use debit cards when making online purchases. Credit card users should be sure to check their statements each month for fraudulent charges. People may also want to consider using temporary cards that have small, fixed lines of credit.
