Kolkata Man Loses ₹8.8 Lakh in 20 Minutes: How to Stay Safe from SIM Swap and Credit Card Scams

A chilling case from Kolkata has once again underlined how vulnerable our digital lives can be. In just 20 minutes, Pankaj Kumar, a resident of Sarsuna, lost ₹8.8 lakh from his credit cards to a sophisticated scam. The transactions were swift, unauthorised, and silent - until it was too late. Here's what happened and how you can protect yourself.

The 20-Minute Financial Heist

Pankaj had no reason to suspect danger. With two credit cards and no history of suspicious activity, he felt secure - until his phone lit up with a stream of OTPs. By the time he managed to block the cards, the damage was done: ₹8.8 lakh wiped out through rapid online purchases.

Preliminary investigations suggest a SIM-swap or a data breach was behind the attack, allowing the scammer to bypass security layers. A man named Kartik Sable has been linked to the crime, exposing how mobile-based financial fraud is on the rise in urban areas like Kolkata.

SIM-Swap Scam : What Is It?

In a SIM-swap attack, cybercriminals trick your mobile service provider into transferring your phone number to their SIM card. Once successful, they intercept OTPs, SMS alerts, and even reset passwords - giving them full control of your banking apps and financial credentials.

Smart Steps to Safeguard Yourself

1. Never Share Sensitive Information

No bank will ever ask for OTPs, CVV numbers, or PINs over a call, message, or email. If someone does, hang up immediately and call your bank’s official helpline.

2. Stay Alert to SIM Swap Signs

If your phone suddenly loses network or displays “SIM deactivated,” it could be a red flag. Contact your mobile operator right away and activate porting locks or SIM PIN features for added protection.

3. Don’t Ignore Minor Transactions

Scammers often test the waters with small transactions before hitting big. Report even the smallest unknown charges or alerts to your bank immediately.

4. Use Virtual or Secondary Cards Online

Opt for virtual cards or low-limit secondary cards for online shopping. These offer a safety buffer in case your primary card data is compromised.

5. Secure Your Digital Footprint

Avoid storing card details unencrypted. Use antivirus tools, enable two-factor authentication, and rely on password managers to keep credentials safe.

6. Be Wary of Impersonators

Today’s scammers disguise themselves as customer care executives, health workers, or even government officials. Always verify identities through official websites or helplines, no matter how convincing the caller may sound.

7. Act Fast if You Suspect Fraud

Time is crucial. Report frauds immediately on cybercrime.gov.in and alert your bank. The quicker you react, the higher your chances of recovering lost money.

Why These Scams Work So Well

It’s not just about stealing your money - it’s about outsmarting your defences. SIM-swap attacks enable fraudsters to intercept OTPs without raising alarms. When combined with social engineering tactics or insider help, even the most cautious individuals can become targets.

Digital convenience comes with its share of risks. But with vigilance, awareness, and a few smart practices, you can stay several steps ahead of scammers. Don’t wait for a 20-minute disaster to take action - start protecting your digital life now.
