Fraud and scams

Ever noticed a transaction on your account that seemed out of place? It could be fraudulent, but many unrecognised transactions can be cleared up with a little investigation. Here’s how you can check:

Ask any secondary cardholders if they’ve made a transaction you aren’t aware of.
See if the merchant is legitimate by using the government’s ABN Lookup.
Google the billing name on your statement because lots of businesses trade under a different name. If you know the merchant, the easiest way to dispute a transaction may be to get in touch with them directly. If you know the merchant but can’t contact them, you can submit a transaction dispute with our Dispute Team.

If you still can’t identify the transaction, it may be fraud. Our Fraud Team monitors your cards 24/7 for suspicious activity – and they’ll send you an SMS if they notice anything unusual. Sometimes a transaction that looks legitimate may have been made without your consent. If you think this is the case, call us.

Phishing scams

Criminals use phishing emails, text messages and phone calls to gain personal identity information like login credentials for banking or email accounts. Phishing emails and text messages often have links or attachments that download malicious software onto your device, or ask you to process a payment. These messages may look legitimate, but there are ways to tell if they’re not.

Usually, phishing email or SMS messages:

Appear to come from a know organisation or contact, but may be from a sender you have never met
Aren’t addressed to you individually
Have a link or button to click on, or asks you to hand over personal details, open an attachment or process a transaction.

Usually, in a phishing phone call:

The caller says they are from a bank, a large service provider like Microsoft, the NBN or Telstra, or the ATO.
They may know some of your personal details like your employee number or work address and use it to gain your confidence, or offer to let you speak with their ‘manager’.
They may ask for SMS codes, or get you to process a transaction or download software so that they can remotely access your computer.

What to do if you’re targeted by a phishing scam

Investment scams

Australians lose millions to investment scams every year. In these scams, individuals or businesses receive a cold call, and are offered attractive investment returns or professional-sounding business opportunities. Once the investment is made, the victim usually receives no returns.

These scammers are mainly based overseas and often tell victims they only need to invest $1000-$2000 to start seeing returns. Often this escalates into requests for more money. Most victims never see any return and lose their entire investment.

Choose your investments wisely

If a stockbroker or investment manager you don’t know contacts you directly, research the company online, and read reviews before committing.

You should also check their business isn’t on the ASIC list of companies you should not deal with.

Business email compromise and invoice scams

Criminal hackers try to steal business email account credentials, because they’re usually a treasure trove of useful information. When a business’s email account is compromised, criminals can use it to request payments or alter invoice details. For example, they can pretend to be the company CEO and send an urgent request to pay an invoice. In 2018, accidental payments to fraudulently altered bank accounts and invoices cost Australian businesses more than $60 million dollars.

Check when things change

If a business asks you to update their bank account details or pay an invoice to a new account, pick up the phone to verbally confirm the change. Use a known or publicly available phone number.

Romance and friendship scams

Today, it’s easier than ever to make friends and build relationships online. The down side is criminals have become clever at taking advantage of people looking for love. Scammers may be looking for financial gain, to gather information or to use their new ‘friends’ to help them launder money.

Remote access scams

Some phone scammers impersonate a bank, telco or computer company and tell you there’s an issue with your computer, banking or phone. They’ll ask you to download a program that gives them remote access to your computer, so they can ‘fix’ the issue. If you do this, they can access all the information on your computer. You should never give an unsolicited caller access to your computer.

Identity takeover

Identity theft or takeover is when a criminal has enough information about an individual to impersonate them for financial gain or other benefits. Criminals can gather your details by stealing from your letterbox or through phishing scams, data breaches, social engineering, malware or hacking systems. When they have enough information, they can attempt to apply for finance, open bank or mobile accounts, or set up other services in your name.

How to protect your identity

Don’t give out any personal information unsolicited phone calls, text messages or emails
Put a padlock on your letterbox
Check your credit rating from time to time so if someone does an unauthorised credit application you will see it listed on the report and be able to take action with the institution (you can do this at ASIC MoneySmart).
Regularly update the anti-virus software on all your devices - find out how to protect your computer with anti-virus software.

Phone porting

Some criminals may try to access your accounts by illegally ‘porting’ your mobile phone number to a new service provider. From there, they can easily access your apps – including mobile banking and email accounts.

Stay sharp

If you get a text message or email from your telco provider about a request that you haven’t made, or your phone goes into SOS mode while other people’s services are still active, call your provider immediately.
