Why Human Error Is Still the #1 Cyber Threat to Small Businesses

In today’s digital landscape, small businesses are increasingly vulnerable to cyber threats. While many focus on external dangers like hackers and malware, the most significant risk often comes from within: human error.

The Human Factor in Cybersecurity

The Office of the Australian Information Commissioner (OAIC) reported that 29% of data breaches in the second half of 2024 were due to human error.

And according to the Australian Cyber Security Magazine, cybercriminals are increasingly targeting the weakest point in any organisation — its people. Despite advancements in cybersecurity technology, human error remains a major vulnerability, with mistakes such as clicking on phishing links, poor password practices, and mishandling sensitive data leaving small businesses exposed. Businesses often underestimate this internal risk, making regular staff training and a strong security culture essential components of any effective cyber defence strategy.

Fakes At Work

A recent report by The Australian highlights the escalating threat of deepfake scams targeting businesses across the country. According to the article, scammers are leveraging advanced, low-cost technology to create convincing fake visual and audio content, including emails, invoices, and even video conference calls with fake executive impersonations. MasterCard reports that 20% of businesses have been targeted over the past year, with incidents resulting in tens of millions of dollars in losses. Many businesses remain unprepared for such sophisticated attacks, underscoring the need for increased employee education and robust cybersecurity measures.

3 Most Common Employee Errors Leading to Breaches

  1. Phishing Attacks: Employees may inadvertently click on malicious links or attachments, compromising sensitive data.
  2. Weak Passwords: Using easily guessable passwords or reusing them across platforms increases vulnerability.
  3. Lack of Training: Without proper cybersecurity education, staff may not recognize potential threats or understand best practices.

The Cost of Human Error

The financial implications of human-induced cyber incidents are substantial. The Australian Cyber Security Centre reported that the average cost of cybercrime for small businesses rose to $49,600 in 2024, marking an 8% increase from the previous year.

Moreover, the indirect costs associated with reputational harm can be long-lasting. The loss of consumer confidence following a breach can lead to decreased revenue and market share, with recovery efforts often requiring significant time and resources .

Mitigating Human Risk

To protect your business:

  • Implement Regular Training: Educate employees about cybersecurity threats and safe practices.
  • Establish Clear Policies: Develop and enforce guidelines for data handling and security protocols.
  • Use Multi-Factor Authentication (MFA): Adding an extra layer of security can prevent unauthorized access.
  • Conduct Regular Audits: Assess and update security measures to address evolving threats.

Conclusion

While technology plays a crucial role in cybersecurity, human behaviour is a pivotal factor. By acknowledging and addressing the risks associated with human error, small businesses can significantly enhance their security posture.
