5 Sneaky Ways Fraudsters Steal Your Credit Card — And How To Fight Back
It could happen to anyone. Even you.

Oddly, he hadn't clicked on any dubious links, nor had he shared his card details with anyone. And yet, there they were: transactions for Facebook ads he had never authorised.
If you're scratching your head thinking, "How could that happen?" — you're not alone. Credit card fraud is a slippery beast, and it doesn't always require a grand mistake to sneak into your life.
Here's how it happens — and what you can do about it.

1. Data breach
Even if you stick religiously to trusted retailers, your information isn't bulletproof. Retailers, social media platforms, and even subscription services suffer data breaches.
If your card details were ever saved on one of these systems, it could have been leaked, bought, and sold before you even noticed.
The worst part? You might not even hear about the breach until months later — if at all.

2. Card skimming
Remember the last time you paid at a petrol station or used a standalone ATM?
Skimming devices — tiny machines placed over real card readers — capture your card's magnetic strip data without you noticing.
Some even install hidden cameras to record your PIN. It's old-fashioned, but it still works frighteningly well.

3. Compromised stored payment info
If you've ever stored your card on social media platforms, online shopping sites, or streaming services, you're trusting that platform's security.
If your account gets hacked (sometimes simply because you reused a weak password), fraudsters can gain access to not just your account, but to your payment details too.
This is especially relevant if fraudulent transactions are tied to Facebook ads, as in my friend's case. It suggests either an account compromise, or worse, a payment detail leak elsewhere.

4. Malware
You might feel confident you've never clicked a bad link. But malware today doesn't always need a flashing pop-up or dodgy email.
A hidden app, an infected attachment from a familiar contact, even a compromised website you visit once — these can install spyware that quietly harvests your saved passwords, keystrokes, and financial data.
If it sounds like something out of a film, well, the truth isn't that far off.

5. Random number generation
Finally, there's brute force. Some fraudsters use software that generates millions of random card numbers and tests them for small, unnoticed charges.
If your card was issued from a major bank, it's a needle in a haystack for them — but with automation, they can find that needle.
Some platforms don't always flag minor transactions immediately, allowing a few fraudulent charges to slip through before alarms sound.

If you notice any suspicious charges, don't delay. Here's your checklist:
- Cancel the card: Call your bank, explain the situation, and request a new card immediately.
- Audit your accounts: Check your social media accounts, email, and any site where your card was stored for strange activity.
- Change your passwords: Start with your email, social media accounts, and banking apps. Use strong, unique passwords and enable two-factor authentication (2FA) wherever possible.
- Monitor your statements: Fraud often comes in waves. Watch your accounts carefully for the next few months.
- Scan your devices: Run a thorough antivirus and malware check on your laptop, phone, and tablet.
The truth is, you can do everything "right" and still fall victim.
But swift action makes all the difference between a few fraudulent charges and a full-blown financial nightmare.
