Protecting Against Phishing Attacks: Essential Tips for Australian Organisations
Phishing attacks are a persistent and evolving threat to businesses of all sizes in Australia. These deceptive attempts to steal sensitive information, such as usernames, passwords, and credit card details, can have devastating consequences, including financial losses, reputational damage, and legal liabilities. This article provides essential tips and strategies for Australian organisations to protect themselves against phishing attacks.
1. Recognising Phishing Emails: Red Flags
The first line of defence against phishing is the ability to recognise a suspicious email. Train your employees to be vigilant and look for the following red flags:
Generic Greetings: Phishing emails often use generic greetings like "Dear Customer" or "Dear User" instead of addressing you by name. A legitimate email from a company you do business with will usually use your name.
Suspicious Sender Address: Carefully examine the sender's email address. Look for misspellings, unusual domain names, or addresses that don't match the organisation they claim to be from. For example, an email claiming to be from your bank might come from "support@bank-online.com" instead of "support@yourbank.com.au".
Urgent or Threatening Language: Phishing emails often create a sense of urgency or use threatening language to pressure you into taking immediate action. They might claim your account will be suspended or that you'll miss a deadline if you don't respond immediately.
Grammatical Errors and Typos: Poor grammar and spelling are common indicators of phishing emails. Legitimate organisations typically have professional communication standards.
Requests for Personal Information: Be wary of emails that ask you to provide sensitive personal information, such as your password, credit card details, or bank account number. Legitimate organisations will rarely request this information via email.
Suspicious Links and Attachments: Hover over links before clicking on them to see where they lead. If the URL looks suspicious or doesn't match the organisation's website, don't click it. Avoid opening attachments from unknown senders, as they may contain malware. A common mistake is assuming a PDF file is safe - PDFs can contain malicious code.
Inconsistencies: Look for inconsistencies between the email's content and the sender's supposed identity. For example, does the email signature match the sender's email address? Does the tone of the email match the organisation's usual communication style?
Real-World Scenario
Imagine an employee receives an email claiming to be from the Australian Taxation Office (ATO), stating that they are owed a tax refund. The email asks them to click on a link to claim their refund. However, the link leads to a fake website that looks like the ATO website but asks for their bank account details and Tax File Number. By recognising the red flags – the generic greeting, the urgent tone, and the request for sensitive information – the employee can avoid becoming a victim of this phishing attack.
2. Employee Training on Phishing Awareness
Regular employee training is crucial for building a strong defence against phishing attacks. Training should cover:
Identifying Phishing Emails: Teach employees how to recognise the red flags mentioned above.
Safe Browsing Practices: Educate employees about safe browsing habits, such as avoiding suspicious websites and being cautious about downloading files from the internet.
Password Security: Emphasise the importance of using strong, unique passwords for each online account and avoiding reusing passwords. Consider using a password manager.
Reporting Procedures: Clearly outline the procedures for reporting suspected phishing emails. Make it easy for employees to report suspicious emails without fear of reprisal.
Consequences of Phishing Attacks: Explain the potential consequences of falling victim to a phishing attack, both for the individual and the organisation.
Training Methods
Interactive Workshops: Conduct interactive workshops that allow employees to practice identifying phishing emails in a safe environment.
Online Training Modules: Use online training modules that cover various aspects of phishing awareness and provide quizzes to test knowledge.
Regular Updates: Keep training materials up-to-date with the latest phishing trends and techniques.
Simulated Phishing Exercises: Conduct simulated phishing exercises to test employees' awareness and identify areas for improvement (covered in more detail below).
3. Implementing Email Security Measures
Implementing robust email security measures is essential for preventing phishing emails from reaching your employees' inboxes. Consider the following:
Spam Filters: Use spam filters to block unwanted emails, including phishing attempts. Configure your spam filters to be aggressive but not overly restrictive, as this can result in legitimate emails being blocked.
Anti-Malware Software: Install anti-malware software on all computers and devices to detect and remove malicious software, including malware delivered via phishing emails.
Email Authentication Protocols: Implement email authentication protocols such as Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting & Conformance (DMARC). These protocols help verify the authenticity of email senders and prevent email spoofing. Many organisations find our services helpful in setting these up.
Multi-Factor Authentication (MFA): Enable MFA for all email accounts and other critical systems. MFA adds an extra layer of security by requiring users to provide two or more forms of authentication, such as a password and a code sent to their mobile phone.
Email Encryption: Use email encryption to protect sensitive information transmitted via email. Encryption ensures that only the intended recipient can read the email's contents.
4. Reporting Phishing Attacks
Establishing a clear and easy-to-use reporting system is crucial for identifying and responding to phishing attacks quickly. Encourage employees to report any suspicious emails they receive, even if they're not sure whether they're legitimate. When an employee reports a suspected phishing email:
Investigate the Report: Immediately investigate the report to determine whether the email is indeed a phishing attempt.
Alert Other Employees: If the email is confirmed to be a phishing attack, alert other employees to be on the lookout for similar emails.
Report to Authorities: Report the phishing attack to the relevant authorities, such as the Australian Cyber Security Centre (ACSC) or Scamwatch.
Review Security Measures: Review your existing security measures to identify any weaknesses that may have allowed the phishing email to bypass your defences. Cyberinsight can help with this process.
Common Mistakes to Avoid
Ignoring Reports: Don't ignore reports of suspected phishing emails. Even if an employee is mistaken, it's better to err on the side of caution.
Blaming Employees: Avoid blaming employees who fall victim to phishing attacks. Instead, use the incident as an opportunity to improve training and security measures.
5. Simulated Phishing Exercises
Simulated phishing exercises are a valuable tool for testing employees' awareness of phishing attacks and identifying areas for improvement. These exercises involve sending realistic-looking phishing emails to employees and tracking who clicks on the links or opens the attachments. The results of these exercises can be used to tailor training programmes and improve security measures.
Realistic Scenarios: Create realistic phishing scenarios that mimic real-world attacks. Use current events or trending topics to make the emails more believable.
Varying Difficulty Levels: Vary the difficulty levels of the phishing emails to challenge employees of all skill levels.
Provide Feedback: Provide employees with feedback on their performance in the exercises. Explain why the email was a phishing attempt and how they could have recognised it.
Positive Reinforcement: Offer positive reinforcement to employees who successfully identify and report phishing emails.
Legal Considerations
Before conducting simulated phishing exercises, be sure to consult with legal counsel to ensure compliance with privacy laws and regulations. It's important to obtain employees' consent before enrolling them in the exercises and to handle their personal information responsibly.

6. Staying Updated on Phishing Trends
Phishing techniques are constantly evolving, so it's essential to stay updated on the latest trends and threats. This can be achieved by:
Subscribing to Security Newsletters: Subscribe to security newsletters and blogs from reputable sources, such as the ACSC and security vendors.
Attending Industry Conferences: Attend industry conferences and webinars to learn about the latest phishing trends and best practices.
Monitoring Social Media: Monitor social media for reports of new phishing scams and techniques.
- Sharing Information: Share information about new phishing trends and threats with your employees. Encourage them to share any suspicious emails they receive with the IT department.
By implementing these essential tips, Australian organisations can significantly reduce their risk of falling victim to phishing attacks and protect their sensitive information. Remember that a layered approach to security, combining technical measures with employee training and awareness, is the most effective way to defend against this persistent threat.
