How to prevent scams

Scams rely on people within a business being tricked into transferring money to accounts they shouldn't. To prevent scams, we encourage the following:

Call first

Before you make a first-time payment for any amount you are not prepared to lose, call the person or organisation you are paying on a trusted number.

Set strong, unique passwords

Ensure all of your accounts, especially email accounts, have strong, unique passwords and are setup with second-factor authentication (e.g. SMS).

Use an approval process

Setup a payments approval process for your business, preferably requiring multiple approvers, with no exceptions.

A culture of questioning

Encourage a culture where staff are comfortable to question a payment instruction even if it’s from a senior executive.

Business email compromise (BEC)

Business email compromise scams target businesses of all sizes. They involve emails from a compromised email address, or emails made to look like they are from someone you know, such as:

  • Your boss
  • Your supplier
  • Your customer
  • Your lawyer

These scams involve emails sent to you or your business with a request to make payment to a new account. This new account may be under the scammer's control, and your money could be lost. If you get an email with a request to pay a new account, or an invoice with different account details to those usually used - pause, review, reflect. Think about calling the sender of the email before paying.

Payroll scams

  • One BEC variation that's prevalent is payroll scams. In these kinds of scams, cyber criminals impersonate employees in an attempt to trick staff into redirecting funds to the scammer. Staff working in HR, payroll or finance are most at risk.

    • The emails they receive might look official or even appear to come from a legitimate employee email address. 
    • They might ask for an urgent update of bank account details to a scammer account instead.
    • In other cases, the first email will seem harmless, simply asking what the process for updating payment details is. The idea is to later make contact with a more targeted follow-up.

    Educating staff on how to spot these fraudulent emails will mean your business isn’t compromised and money isn’t lost. Here’s how to keep your business safe, as recommended by the Australian Cyber Security Centre.

    1. If an email appears suspicious, don’t reply or click on any links. Instead, look up the person’s email address and create a new email to verify the request being made. If your company’s database lists phone numbers, give them a call to quickly check the email’s validity
    2. Always set a strong, unique, two-factor authentication password with your email. If you receive a notification about a bank account update you didn’t authorise, contact payroll immediately
    3. Frequently check your bank accounts for any unusual activity

Educate your staff

It’s vital to educate your staff on what common scams look like so they can recognise them, report them and help safeguard your business from potentially costly mistakes.

Understanding business email scams

Email scams that target business have evolved and these days often look very similar to legitimate business emails, such as an expected invoice or payment request. That's why it's important to understand how they work.

  • Not sure whether a message is legitimate?
