How to Protect Your Perth Business from Email Scams and Phishing

Most people picture a hacker breaking into a business through some clever piece of technical wizardry. In reality, the overwhelming majority of successful attacks on Australian businesses begin with something far more ordinary: an email. A staff member receives a message that looks legitimate, clicks a link or shares a password, and within minutes an attacker has a foothold in your systems.

This is phishing, and it remains the single most common entry point for cybercrime affecting small and medium businesses across Perth. The good news is that phishing relies on tricking people rather than defeating technology, which means a well-informed team and a few sensible safeguards can dramatically reduce your risk.

This guide explains what phishing is, how to recognise it, and the practical steps your Perth business can take to protect itself, all in plain language without the scare tactics.

What is phishing and why are Perth businesses targeted?

Phishing is a type of scam where criminals send messages pretending to be a trusted source, such as a bank, a supplier, a government agency or even a colleague. The aim is to trick the recipient into revealing sensitive information, transferring money or clicking a link that installs malicious software.

Small and medium businesses are popular targets precisely because attackers assume they have fewer defences than large corporations and less awareness among staff. A local Perth trades business, accounting firm or medical practice may not feel like an obvious target, but to a scammer running thousands of automated attempts, every inbox is an opportunity. The information held by everyday businesses, including customer records, banking details and email access, has real value on the criminal market.

What are the most common types of email scams?

Phishing comes in several recognisable forms, and knowing them makes them far easier to spot:

• General phishing: mass emails impersonating well-known brands, asking you to verify an account or update payment details through a fake link.
• Spear phishing: a targeted message aimed at a specific person, often using real names and details gathered from social media or your website to seem convincing.
• Business email compromise: an attacker poses as a senior staff member or supplier and requests an urgent payment or a change to bank account details.
• Invoice fraud: a genuine-looking invoice arrives with altered banking details, hoping accounts staff pay without checking.

Business email compromise and invoice fraud are particularly costly for Perth businesses because they target the payment process directly and can result in large sums being transferred before anyone notices.

How can you tell if an email is a phishing attempt?

Phishing emails almost always carry warning signs once you know what to look for. Encourage every member of your team to pause and check the following before acting on any unexpected message:

1. A sense of urgency or threat, such as a warning that your account will be closed or a payment is overdue, designed to make you act before thinking.
2. A sender address that looks slightly wrong, for example a misspelt company name or a public email domain where a business one is expected.
3. Links that do not match the supposed sender when you hover over them without clicking.
4. Requests for passwords, banking details or payments that arrive unexpectedly or break normal procedure.
5. Spelling and grammar that feel slightly off, or a greeting that is oddly generic.

As a simple rule, if a message asks you to do something urgent involving money, passwords or personal details, treat it with suspicion and verify it through a separate channel before acting.

What practical steps protect your business from phishing?

Strong phishing protection in Perth comes from combining good habits with sensible technology. No single measure is foolproof, but layered together they make your business a far harder target.

Turn on multi-factor authentication

Multi-factor authentication requires a second form of verification, such as a code on a phone, in addition to a password. Even if a scammer steals a password through phishing, they cannot log in without that second factor. This is one of the most effective single steps any business can take.

Train your team regularly

Your people are your first line of defence. Short, regular training that shows real examples of scams helps staff recognise threats and feel confident reporting anything suspicious. A team that knows it is safe to ask is far stronger than one that quietly clicks and hopes for the best.

Verify payment and account changes

Put a simple rule in place that any request to change bank details or make an unusual payment must be confirmed by a phone call to a known number, never by replying to the email. This one habit defeats the majority of invoice fraud and business email compromise attempts.

Use email filtering and security tools

Modern email security can block a large proportion of phishing messages before they ever reach an inbox. Properly configured Microsoft 365 security settings, for example, add powerful protection that many businesses already pay for but have never switched on.

Keep software updated and data backed up

Up-to-date systems close the security gaps that malicious links try to exploit, while reliable backups mean that even a successful attack does not have to end in lost data. A tested backup and disaster recovery plan is the safety net that turns a potential catastrophe into a manageable inconvenience.

Phishing red flags at a glance

Warning Sign	What To Do
Urgent demand for payment or action	Pause and verify by phone
Unexpected request for passwords	Never share; report it
Sender address looks slightly wrong	Check carefully before replying
Change of bank account details	Confirm via a known phone number
Link that does not match the sender	Do not click; delete or report

 

What should you do if someone falls for a phishing email?

Mistakes happen, even to careful people, so it helps to have a plan. If a staff member realises they have clicked a suspicious link or entered their details, act quickly. Change the affected passwords immediately, enable multi-factor authentication if it is not already on, and disconnect the device from the network if you suspect malicious software. Then contact your IT provider so the incident can be investigated and contained.

Above all, foster a culture where reporting a mistake is encouraged rather than punished. The sooner an incident is reported, the easier it is to limit the damage.

Building lasting protection for your Perth business

Phishing will not disappear, but it does not have to put your business at risk. By combining alert, well-trained staff with multi-factor authentication, sensible payment checks and properly configured email security, you can stop the vast majority of attacks before they cause harm.
