Card fraud is when someone uses your bank cards or card details to make purchases you didn’t authorise.

How card fraud happens

Here are the most common ways card fraud can occur

A database breach is a violation of any personal/confidential information (including cards details) you may have disclosed to a company, organisation or another third party, through either theft or loss. It can occur as a result of an unintentional breach by, or via a deliberate attack on, a company, organisation, third party and/or website you may have used before.

Fraudsters take the first 6 digits of your card number and use software to generate the remaining sequence of numbers. Combinations of card numbers, expiration dates and CVCs are tested to see if they’re correct and active. When successful combinations are found, card details can be used to make unauthorised transactions.

When fraudsters get hold of your full card credentials, generally through the black market or through a database breach, they can use these details to make a large number of purchases without your knowledge.

ATMs or EFTPOS machines can be tampered with to copy the magnetic strip on your card and record the PIN you enter. Fraudsters can then create a counterfeit card and withdraw cash from your account.

Malicious software, like viruses, worms and spyware are designed to disrupt and invade computer systems, to acquire and distribute sensitive information such as credit card numbers. If your mobile phone or computer device becomes infected with malware, any sensitive information stored on the device (including your card numbers or banking passwords) can be stolen. Fraudsters can use your card details to process transactions online or attempt to gain unauthorised access to your online banking account(s).

You’ll never need to give your CVC number when making an in-store purchase. Even if the merchant tells you otherwise, you should only tap, swipe or insert your card into an EFTPOS machine to make a payment. Sometimes you might need to provide your CVC number when making a payment over the phone or online. When doing so, always make sure to check the receipt emailed to you and/or the amount debited from your account.

Mail from CommBank often includes private and important information for yourself only. If stolen, this information can be used to access your accounts, steal funds from your card, used in crime or sold.Contact usstraight away if your mail has been stolen andreport your cards stolen to help prevent any financial loss.

Always make sure your address and contact details are up to dateand are correct.

As soon as you notice your card is missing, lost, misplaced or stolen, report your card lost or stolen to usto stop anyone else from using it. Contact usimmediately if you notice any unauthorised transactions on your account(s) with us.

Never provide any login, password and PIN details, never allowremote accessor share the details of your digital card/s (including screenshots). If you are worried that your details are compromised, lock your cardand report any suspicious activity to us immediately.
