On the fake website, visitors are asked to enter their credit card information to pay for the fake WhatsApp extension. If they enter the requested information their credit cards will be charged for a service that doesn't exist and their credit card information will be stolen and used fraudulently.
WhatsApp users who have already been tricked by the phishing scam are asked to contact their banks and have them cancel the fraudulent transactions and refund their money. They may need to get a new credit card to prevent the cybercriminals from occasionally charging their credit cards for an undetermined amount.
