My friend Ankit ordered a pair of branded running shoes last Friday from a website he saw on Facebook. The shoes were priced at four hundred rupees instead of six thousand.

Two days later, no confirmation email arrived and his bank notified him that someone tried to charge twelve thousand rupees from an overseas merchant.

He ran to my desk panicking: “What do I do now?” I told him to stop looking at the fake tracking page and take control of his bank card immediately.

Think of it like dropping your physical wallet on a busy railway platform. You do not wait around to see if a thief posts your wallet back to you. You cancel your cards right away so nobody can go on a shopping spree with your money.

Here are the three steps I had Ankit follow:

First, open your banking app, open card settings, and tap the freeze button. That shuts off your card instantly.

Second, call your bank customer care and tell them you entered your card numbers on a fraudulent portal. Ask them to permanently block that card and issue a fresh one with a new number and CVV.

Third, turn off international transactions on your banking profile until you actually travel abroad.

To stop yourself from ever opening a fake storefront, install the CYBX mobile app.

CYBX was created by 63SATS to safeguard families against online fraud. CYBX’s link scanner checks websites before your screen opens them. If a site is a fake store clone, CYBX blocks it instantly, keeping your card numbers safe.
