How to Identify and Prevent Data Phishing Attacks in Your Business
Imagine this: you’re flat out on a Tuesday morning, juggling emails and deadlines, when one of your staff members clicks a link in what looks like a legitimate client email. Next thing you know, sensitive business data is compromised. Sound far-fetched? Unfortunately, it’s not. Phishing attacks are one of the most common ways Aussie businesses get breached—and they’re getting trickier to spot.
At Gray Area Consulting, we’ve seen firsthand how phishing can trip up even the savviest teams. Let’s walk through how to identify and prevent these attacks before they wreak havoc in your business.
What is a Phishing Attack?
Phishing is a type of cyber attack where scammers pretend to be trustworthy sources—like a bank, supplier, or even a colleague—to trick someone into providing sensitive info or clicking on malicious links. It’s like a con artist dressing up in a tradie uniform to get into your home. It looks legit, but something’s off.
Common Signs of a Phishing Email
Phishing emails have come a long way from dodgy grammar and suspicious links. These days, some look almost identical to official correspondence. But there are still a few tell-tale signs to watch for:
- Spelling or grammatical errors – even small mistakes can be a red flag
- Urgent language – “Your account will be closed unless you act now” is a common scare tactic
- Strange email addresses – hover over the sender’s email to check if it matches who they claim to be
- Unusual attachments or links – if it’s unexpected, it’s worth double-checking
We recently worked with a Brisbane-based financial services firm that was nearly caught out by a phishing email posing as their accountant. It came complete with a PDF invoice and a link to a login portal. Luckily, their security awareness training kicked in, and the staff member flagged it with us before clicking through.
Types of Phishing Attacks
While email phishing is the most common, there are other sneaky forms to be aware of:
- Spear phishing: Targeted attacks aimed at specific individuals, often using personal info to appear more convincing
- Smishing: Phishing via SMS—these might look like messages from the ATO or Australia Post
- Vishing: Voice phishing, where scammers call pretending to be from your IT provider, bank, or even Microsoft
- Reply-chain attacks: Hackers infiltrate an email thread and pose as a trusted party. Learn more about reply-chain phishing here.
How to Prevent Phishing in Your Business
Prevention starts with awareness and the right mix of tools and training. Here’s how you can reduce your risk:
1. Invest in Security Awareness Training
Make sure your team knows what phishing looks like. Regular training keeps the topic front of mind and helps build your human firewall. We cover this in more detail in our article on why security awareness training is essential.
2. Use Multi-Factor Authentication (MFA)
MFA adds an extra layer of protection. Even if credentials are stolen, the attacker can’t access your systems without the second factor. Learn how to implement it effectively in our guide to Mastering Multi-Factor Authentication.
3. Implement Email Filtering Tools
Modern email security tools can detect and block dodgy messages before they land in inboxes. These tools scan for known threats, suspicious links, and spoofed addresses.
4. Restrict Admin Privileges
Limit admin rights to only those who need them. This helps contain the damage if an account is compromised. It’s also a core requirement of the Essential Eight cybersecurity framework.
5. Keep Software and Systems Updated
Patches fix vulnerabilities that attackers exploit. Staying up to date is one of the simplest yet most effective defences. Read more on why regular software updates matter.
What to Do If You Suspect a Phishing Attack
If someone in your business receives or clicks on a suspicious email, act quickly:
- Disconnect the affected device from the network
- Change any potentially compromised passwords
- Report the incident to your IT team or managed services provider
- Notify impacted stakeholders if necessary (client data, for example)
And don’t forget to review what happened so you can tighten your defences. It’s not about blame — it’s about learning and improving together.
