NAB is aware of a current SMS phishing campaign targeting customers. Please see an example below.

The message claims to be from NAB stating you need to confirm your mobile device to avoid restrictions or that services have been restricted and to restore them by clicking on a link. This leads to a fake NAB website asking for personal information and banking credentials.

Do not click on the link.

NAB will never ask you to confirm, update or disclose personal or banking information via a link in an email or text message.

When sending phishing text messages, criminals sometimes set the sender name as “NAB”, meaning that fraudulent text messages can appear in the same conversation as legitimate messages from NAB. This is not a sign that NAB systems have been breached in any way– it simply means a criminal is impersonating our brand.

If you have received this type of text message, please forward it to 0476 220 003 (047 NAB 0003) or take a screenshot, email it to phish@nab.com.au and then delete the text message.

If you have received this type of email or text message and have clicked on the link or entered your details please contact your local branch or call 13 22 65 immediately.

NAB is aware of purchasing scams targeting Australian consumers, with scammers active on both the buying and selling sides of transactions. These scams take place on the common platforms used by people to buy and sell goods and services, such as eBay, Gumtree, Facebook Marketplace and Carsales.

If you’re selling an item, a scammer may send you a fake or altered receipt claiming they have transferred funds into your account. After you send or hand over the item, they will cease communication without having paid you.

If you’re purchasing an item, a scammer posing as a legitimate seller may post an item for sale which appears to be a good deal. They may put up an advertisement that is fake, or sell items that aren’t rightfully theirs. When you start communicating with them, they may send you pictures of the item which appear to be legitimate. However, these images are often stolen from the Internet or from other legitimate advertisements. Once you pay them, the seller will stop communicating and you won’t receive the item.

Tips to avoid a purchasing scam

Be cautious of buyers and sellers asking for identification documents such as your driver’s license, passport and Medicare card number. Never provide these to someone you don’t know, as it may be used to commit identity fraud.

If you’re purchasing an item, try to meet the buyer in person where possible. If this is not possible, ask them to video call you so you can inspect the item more closely. Conduct a ‘reverse image search’ for the photos of the item you’re buying- you may find the picture of the item already exists on a legitimate ad, or other fake ones.

If you’re selling an item, wait for the funds to arrive in your bank account before you hand over the goods, or accept cash at handover. Don’t rely on receipts provided as they may have been altered.

NAB is aware of current scam phone calls targeting Australians.

You may receive a call where the caller pretends to be from organisations like your bank, Telstra, NBN, Microsoft, Amazon, ATO or the police, or receive a text message asking you to call your bank due to security concerns. Once on the call, the caller may request remote access to your computer and bank accounts, or ask you to provide personal or banking information.

Below is an example of a text message stating there is a problem with a credit card, asking the recipient to call the number to protect their accounts. This leads to a scam call.

Never give an unsolicited caller remote access to your computer or online bank accounts, or provide personal or banking information.

Ensure you read any SMS codes sent to you in full. If it states “Your NAB secret code is xxxxx. Do not provide this to anyone, even NAB”, do not disclose this code to anyone.

If you ever have concerns as to the legitimacy of a call, hang up and call the company back on a publicly available number (e.g. NAB’s number is available on the back of your card).

If you have provided information on this type of call, please contact your local branch or 13 22 65 immediately.

For more information on scam calls, read our article 'How to spot scam phone calls'.

NAB is aware of criminals targeting businesses by stealing their physical merchant terminal and replacing it with a fake or disabled terminal.

Being alert to fraudulent payment activity can reduce the chances of your business falling victim to scams and suffering costly chargebacks and other financial losses. Here are some simple tips you can follow:

• Educate all front-line staff about fraud risks associated with your payment terminal and payment scams in general.
• Keep payment terminals behind the counter or on the person of your employees. Don’t allow customers to edit or manually enter transactions.
• Set a strong terminal password and activate the lock feature when the terminal is unattended. That way if the terminal is stolen, no transactions can be processed by a third party.
• Keep a list of the terminals you have onsite, including their make, model and serial number. Do a daily check to confirm that the data matches.
• Do a physical check at the terminal, to see if there are any changes or if there’s any evidence of tampering.

You can read the full article on fraud risks for more information.

If you are a NAB customer and believe you may have fallen victim to this fraud, please call 13 22 65 immediately and ask for the Merchant Fraud Team.

NAB is aware of Microsoft Exchange vulnerabilities that may allow malicious actors to compromise business networks.

The Australian Cyber Security Centre (ACSC) has issued an advisory on the threat, which impacts the 2013, 2016, and 2019 versions of Microsoft Exchange. Malicious actors are exploiting these vulnerabilities to compromise Microsoft Exchange servers exposed to the internet, enabling the actor to access email accounts and the Exchange server and associated networks.

NAB and the ACSC recommend immediately applying the patches released by Microsoft to all vulnerable Microsoft Exchange servers, as well as undertaking the detection steps outlined in this Microsoft blog post.

For more information, please refer to the ACSC and Microsoft advisories, or contact the ACSC on 1300 CYBER1 (1300 292 371) for assistance.

NAB is aware that Australians are being targeted with investment scams promising lucrative returns. In 2019, Australians reported to the Australian Competition and Consumer Commission (ACCC) a loss of $61 million from investment scams.

The ACCC advises that these fake investment companies are proactively contacting Australians online or by phone, and claiming to be stock brokers offering investment advice, promotions, and hot tips or offering free investment seminars.

The ACCC advises the fraudster will claim what they are offering is low-risk, and will provide you with quick and high returns, or encourage you to invest in overseas companies. The offer may sound very legitimate, with resources to back up their claims. They may say you need to act quickly and invest, or you will miss out.

Before transferring any money to an investment company, check the Australian Securities and Investments Commission’s (ASIC) list of companies that you should not deal with. You can learn more about investment scams on the ACCC’s Scamwatch website, and by reading our investment scams article.

If you believe that you have paid money to an investment scam, please contact NAB immediately on 13 22 65.

NAB is aware of invoice scam attempts targeting Australian businesses.

An invoice scam is when a business receives an emailed invoice from a supplier whose email account has been compromised by a criminal. The criminal will alter the payment details on the invoice to a fraudulent or mule account. As the invoice looks legitimate, the business doesn’t question the payment details, and sends the payment to the fraudulent account.

Another variation of an invoice scam is when a business receives a request advising a supplier’s or employee’s payment details have changed, and to make payments to a new account.

Before processing invoices, check the payment details against the last invoice. If they have changed, or you receive a request to update payment details:

• Do not proceed with the transaction(s), and
• Call the supplier/sender to confirm the legitimacy of the request, using a known contact or publicly listed number. Do not call the number on the new invoice/email.

If you have received an email of this type and actioned the request, please contact NAB on 13 22 65 and ask for the Anti-Scam Investigations Team.

Whilst the bank will make every effort to recall funds, recovery is not guaranteed.

NAB is aware of mobile phone porting attempts targeting Australians.

What is mobile phone porting?
Mobile phone porting describes when your mobile phone number is ported (transferred) to a new telecommunications provider without your permission. This may enable criminals to receive SMS authentication codes sent by your bank, in order to authorise online banking transfers without your knowledge.

How does it occur?
In some cases, all that is required to port a phone number is an account or phone number, and date of birth.

What to look for
If your mobile phone service is suddenly disconnected, it may show ‘SOS only' where the carrier name usually appears on the screen. This could be a warning sign that your mobile phone has been transferred to another provider without your authorisation. If your service does not return in a short period, contact your mobile provider immediately to confirm why your mobile service is not working.

If your mobile has been transferred to another provider without your permission, please contact us on 1300 651 656.

You can learn more by reading our mobile phone porting article.

NAB is aware that scammers are attempting to trick individuals and business customers into accepting and on-forwarding fraudulent funds by criminals who are posing as genuine customers. For example, the scammer may send fraudulent funds to someone who is told it is a legitimate payment or received by mistake; the customer is asked by the scammer to on-send those funds to another account. Customers who accept and onforward these payments are acting as money mules and may be facilitating money laundering, which is a criminal offence.

Only accept payments for your products or services: NAB recommends to never accept payments that need to be forwarded to a third party. Businesses should only accept payments for services or products you supply, and are expecting to receive.

Know your customers: Have a process in place to be able to identify your customers and fully understand the nature of the transactions they are looking to participate in.

Only obtain finance from legitimate sources: It may be tempting to look for lenders with low rates or easy application processes, but make sure that any finance agreements are with accredited financial institutions.

Stop and Think: If something doesn’t seem right about a customer’s request, do some research and ask questions until you are satisfied that the transactions is genuine. You can reserve the right not to proceed with a customer’s request.
