The True Cost of Cyber Attacks on SMEs
Many small and medium-sized Australian businesses still hold the belief that they are unlikely targets for cyber criminals. The assumption is often that cyberattacks are aimed at larger organisations with extensive customer data, complex systems, or high-profile brands. In reality, the opposite is often true.
Smaller businesses are frequently targeted precisely because they usually have fewer protections, less sophisticated security controls, and a higher likelihood of paying a ransom. Cyber incidents are rarely selective about business size or industry, they are typically opportunistic, automated, and driven by access rather than value alone.
The following example claim scenarios illustrate how quickly everyday business activity can be disrupted, and how those disruptions translate into real financial impact.
1. Professional services firm - phishing email compromise
Business Type: Consulting firm (8 staff)
Attack Type: Business email compromise (BEC)
Impact: Fraudulent invoice redirection and email account access
An employee's email account was compromised through a phishing link. Attackers monitored the inbox activity and intercepted an invoice, replacing the bank details with their own before sending it to a long-term client. The client did not realise the change and paid the invoice as normal. The funds were not recovered by the bank.
Claim Breakdown:
- Stolen client payment of $18,000 AUD
- IT forensic investigation
- Email security rebuild (MFA, reconfiguration)
- Legal and incident response advice
- Client communication and remediation
- Productivity disruption
- Total claim: $43,500 AUD
Key takeaway: A single compromised inbox is all it can take to create a five-figure loss.

2. Medical practice - ransomware downtime event
Business Type: Allied health clinic (13 staff)
Attack Type: Ransomware via malicious attachment
Impact: System shutdown for 7 days
A staff member opened a malicious email attachment that triggered ransomware encryption across shared drives and practice management systems. Staff were unable to access patient files or book appointments, reverting to manual processes. Backups were available but required a partial rebuild and validation, disrupting the business operations for 7 days. No ransom demanded.
Claim Breakdown:
- Incident response and forensics
- System restoration
- Backup validation and data recovery support
- IT contractor emergency support
- Business interruption
- Patient communication
- Total claim: $63,500 AUD
Key takeaway: The downtime and recovery costs can often be bigger than the demanded ransom.
3. Manufacturing business - operational shutdown attack
Business Type: Metal fabrication workshop (27 staff)
Attack Type: Ransomware targeting file server
Impact: Production halted for 10 days
A ransomware attack occurred after attackers gained access to the company's network through an unsecured remote access login used by a third-party contractor. Once inside the system, the attackers encrypted critical production schedules, supplier orders, CAD drawings, and quoting systems stored on the company's file server. The business could not operate normally for 10 days until systems were rebuilt.
Claim Breakdown:
- Incident response and cyber forensics
- System rebuild and server recovery
- External IT support
- Business interruption
- Rush order fulfilment / delays
- Cyber security uplift
- Total claim: $150,000 AUD
Key takeaway: Businesses that do not hold much customer data are just as susceptible to a cyberattack as businesses with a lot of customer data.

4. Retail / ecommerce business - website breach
Business Type: Online retail store (21 staff)
Attack Type: Payment system compromise
Impact: Website shutdown and customer data exposure
Attackers exploited a vulnerability in a plugin connected to the business's ecommerce website, allowing unauthorised access to the payment system and customer checkout data. The website was temporarily taken offline while forensic investigators determined the extent of the breach and secured the system. The business was unable to process online orders, and customers were notified that payment information and personal details may have been exposed.
Claim Breakdown:
- Incident response and digital forensics
- Website rebuild and patching
- Legal and privacy advice
- Customer notification and support services
- PR / reputation management
- Lost online sales from website downtime
- Total claim: $107,000 AUD
Key takeaway: Cyber risks do not always originate within the business itself, vulnerabilities in third-party software can also create significant exposure.

5. Construction business - ransomware event
Business Type: Commercial construction company (48 staff)
Attack Type: Ransomware via remote access compromise
Impact: Projects delayed for over two weeks
Attackers gained access to the company's network using compromised remote login credentials linked to a staff account, encrypting project schedules, payroll systems, subcontractor records, and key project documentation. Staff were unable to access current drawings and safety documentation, while payroll processing and subcontractor coordination were also disrupted. Their projects experienced delays for over two weeks.
Claim Breakdown:
- Ransom demand
- Incident response and negotiation support
- Forensic investigation
- System rebuild and recovery
- Business interruption / project delays
- Legal and contractual advice
- Cyber security uplift and monitoring
- Total claim: $213,000 AUD
Key takeaway: Cyberattacks can disrupt how a business operates day to day by impacting the systems that support core business functions, not just data.
Why Cyber Insurance matters
While the circumstances of each incident were different, the outcome was remarkably similar: significant disruption, specialist recovery costs, and financial losses that extended well beyond the initial cyber event. Cyber insurance is designed to help businesses respond to these situations by covering a range of expenses, including forensic investigations, legal advice, system recovery, business interruption, and incident response support. Having the right cover in place can make a significant difference when every hour of downtime matters.
