Now consider, how can a company help a customer protect themselves against this kind of attack? Even given the inherent weaknesses of credit cards, consider this option:
The video says that hackers monetize compromised computers by installing key loggers. The hackers then search through the keyed data looking for credit card numbers. “But we can’t do anything if the customer’s computer is compromised!” B.S.
What’s the solution? Don’t have your customer enter all the digits of the credit card via their keyboard. Display an onscreen keypad for entry of the last four digits. This thwarts the CC thieves and demonstrates to your customers that you are attempting to protect them even on potentially compromised systems. Simple, easy, effective.
