Phishing attacks continue to be the most common and most successful form of cyber attack targeting Australian businesses. Despite advances in email security technology, phishing emails still manage to reach inboxes and trick employees into clicking malicious links, opening infected attachments, or revealing sensitive information.
What is Phishing?
Phishing is a type of cyber attack where criminals send fraudulent messages (usually emails) that appear to come from legitimate sources. The goal is to trick recipients into revealing sensitive information (like passwords or credit card numbers), clicking malicious links that install malware, or transferring money to fraudulent accounts.
Common Types of Phishing
Email Phishing The most common form — mass emails sent to thousands of recipients, impersonating banks, technology companies, or government agencies.
Spear Phishing Targeted emails crafted for a specific individual or organisation. These are much harder to detect because they're personalised and often reference real business relationships or events.
Business Email Compromise (BEC) Sophisticated attacks where criminals impersonate executives or business partners to trick employees into making wire transfers or sharing sensitive data. BEC attacks cost Australian businesses millions of dollars each year.
SMS Phishing (Smishing) Phishing messages sent via text message, often impersonating delivery companies, banks, or government services.
How to Protect Your Business
1. Implement Email Security Deploy advanced email filtering that uses machine learning to detect and block phishing emails. Standard spam filters catch obvious threats, but advanced solutions can detect sophisticated phishing attempts that would otherwise reach your inbox.
2. Enable Multi-Factor Authentication MFA is your best defence against credential theft. Even if an employee's password is compromised through a phishing attack, MFA prevents the attacker from accessing the account.
3. Conduct Security Awareness Training Your employees are your first line of defence. Regular training helps them recognise phishing attempts and respond appropriately. Include simulated phishing exercises to test and reinforce the training.
4. Establish Verification Procedures Create procedures for verifying requests that involve money transfers, sensitive information, or changes to payment details. A simple phone call to verify an unusual request can prevent a costly BEC attack.
5. Keep Systems Updated Ensure all software, operating systems, and applications are kept up to date. Many phishing attacks exploit known vulnerabilities in outdated software.
6. Implement DNS Filtering DNS filtering blocks access to known malicious websites. Even if an employee clicks a phishing link, DNS filtering can prevent them from reaching the malicious site.
7. Have an Incident Response Plan Know what to do if a phishing attack succeeds. Having a documented incident response plan ensures your team can react quickly to minimise damage.
