How do Fraudsters get your bank details

miffed79

I spoke to Natwest today who told me that an attempt had been made on my card to test the card for 1p. Apparently Fraudsters do this to see if the account works. The charge came from Carphonewarehouse and I've never used carphonewarehouse.

Natwest stopped the card and as far as I am aware there are no major problems, but it has left me wondering....

I would never in a million years respond to any phishing e-mails or give out my details unless I had called one of the official Natwest numbers.

I use good anti-virus software on my pc's so I cannot see for the life of me how they got this information.

Any ideas?

They could have skimmed you card details from an ATM machine or at a retailer. If you have done any shopping online where this website ain't totally secure they can access your details.

Have you purchased anything from any nobile phone retailer? CPW trade under a variety of different names so you may not have been aware you were buying from CPW. They thenselves process these 1p test transactions before dispatching a phone.

In terms of fraudulent transactions, how do fraudsters get card numbers? ever thrown away a receipt which has your card details printed on it? What about the retailer? if they've just chucked the audit roll from the till in the bin after 6 months it'd be easy for any dumpster diver to get you card details.

Ever handed your card over in a restraunt or petrol station?

Asda always put through a transaction for petrol at 1p. It sits pending on my Capital One credit card for a couple of days before the correct amount is put through.

There are tonnes of ways that your card details can be obtained even if you are careful - from skimming when your card is out of your eye sight, to a shop or bank throwing out your details in an unsecured way to a crooked employee at a foreign call centre.

In short there is no way of knowing.

I was about to say the same as olly... Most of the call centres for banks are abroad, working terrible wage. What other way better to make extra income then selling the infomation on of the people you served that day... Don't forget, when you call them, they ask for all your details, and most of them they already know.

They make them up - they have computer programmes that generate massive numbers of random 16-digit card numbers, expiry dates and CCV codes. They then try all of these for tiny transactions (places like Carphone Warehouse and iTunes are popular), and every now and then, one will come back as a genuine card.

There's nothing that you can do to stop this other than keeping an eye on your bank statements and hoping that your bank will notice straight away.

What I find odd is, does iTunes not notice a massive ammount of numbers being dialed through its server from the same I.P address, rapidly within seconds? Seen as its a bot program, I would like to think have a gazzion I.P's for yourself is impossible without having to reset it every 10 seconds or so, and wait a minute for it to utilize. If this is the case, then god damn.... They have a few good trillion tries to go through, in the next 50 years to land a few working credit cards. :cool:

They don't.

sure you can generate them if you like, but the probabilities of getting a good one are extremely small.

Now, that of course wouldn't put fraudsters off if they had the ability to rapidly test billions of card numbers and CVVs until they get a hit, but they don't.

No, iTunes require you to register an account with them; this abuse generally comes from people whose iTunes account becomes compromised.

Couple that with the fact that very often, the person whose account has been taken is also probably being used as a botnet zombie, the IP address willl simply show as their own.
