Why Phishing Is Still the #1 Entry Point for Cybercriminals

4 min read · February 2025 · By IntrusionX Security Team

More than 90% of successful cyberattacks begin with a phishing email. Despite decades of awareness campaigns, phishing remains devastatingly effective — and attackers are getting better at it every year, using AI to craft personalised, convincing messages at scale.

What Is Phishing?

Phishing is a social engineering attack where criminals impersonate trusted organisations — banks, the ATO, Australia Post, Microsoft, or even your own colleagues — to trick you into revealing passwords, clicking malicious links, or transferring money.

Common Phishing Tactics Used Against Australians

Fake ATO or myGov Notices

Emails claiming you owe a tax debt or that your account needs verification — linking to convincing fake login pages.

Australia Post / Courier Scams

SMS and email messages claiming a parcel is held, requiring you to pay a small fee or enter delivery details.

Business Email Compromise (BEC)

Attackers impersonate a CEO or finance manager to instruct staff to transfer funds urgently or update bank account details.

Microsoft / Google Account Alerts

Fake security alerts claiming your account has been compromised, directing you to enter credentials on a spoofed login page.

Invoice Fraud

Legitimate-looking invoices from impersonated suppliers with modified bank account details to redirect payments.

How to Spot a Phishing Email

The sender's email address doesn't match the organisation it claims to be from
Urgent or threatening language demanding immediate action
Links that don't match the claimed destination (hover before clicking)
Poor spelling, grammar or unusual formatting
Requests for passwords, banking details or Tax File Numbers via email
Unexpected attachments — especially .zip, .exe, .docm files

How to Protect Against Phishing

Deploy email filtering with anti-phishing and sandboxing technology
Enable multi-factor authentication (MFA) — so stolen passwords alone aren't enough
Conduct regular staff phishing simulation training
Implement DMARC, DKIM and SPF email authentication records
Use endpoint protection that blocks known malicious URLs in real time
Establish a clear process for verifying bank account changes and payment requests verbally
