Cyber attacks are increasing – and small businesses are in the firing line. When a cyber criminal strikes, there’s more than compromised data at stake. For many businesses, a successful cyberattack can rapidly evolve into a cash flow crisis.
Cybercrime is now estimated to cost Australian small businesses $300 million annually. It’s no wonder then, that cyber incidents – including ransomware, data breaches and IT outages – were ranked the number one global business risk in the Allianz Risk Barometer.
While cyber attacks on large corporations like Optus, Medibank, and Qantas dominate the headlines, it’s the 2.5 million Australian SMEs that are being hit the hardest.
“Small businesses are often prime targets for cybercriminals due to their limited resources and expertise in what is deemed ‘best practice’ with regards to cyber security,” says Evan Vougdis, Head of Cyber Intelligence and Cyber Response & Recovery at NSB Cyber.
The Australian Cyber Security Centre (ACSC) advises businesses to treat cyber incidents as a “when” – not an “if” – and ensure a robust cybersecurity incident response plan is in place.
Why SMEs are more vulnerable to cyber attacks
SMEs are consistently among the most targeted – and least prepared – for cybercrime.
“Unlike larger organisations, small businesses typically lack dedicated IT security teams, advanced tools, or comprehensive defences, making them easier to breach,” says Evan.
According to the ACSC, the average cost of an attack on an Australian small business is $49,600, up 8% from the previous year. Larger firms may face higher dollar losses but usually have insurance and systems in place to absorb the impact.
But the damage isn’t just financial. It takes an average of 7.3 months to recover from a major cyber event – often involving downtime, lost productivity, and reputational harm.
The latter is one of the biggest risks for businesses, with 40% of consumers saying they would often or always stop business with a company after learning of a data breach – even if their own data hadn’t been compromised.
What are the most common cyber threats facing small businesses?
The most common cyber security risks for small businesses? Email compromise (20%); business email compromise fraud – where the email compromise includes a direct financial loss – (13%); and online banking fraud (13%), according to the ACSC.
Some industries are targeted more frequently than others. In 2023–24, the top sectors reporting cybercrime in Australia included:
- Retail – 15%
- Professional, scientific and technical services – 13%
- Construction & engineering – 12%
- Financial and insurance services – 8%
- Other services – 7%
“Cybercriminals are increasingly using supply chain attacks to exploit financially unstable businesses as weak links,” says Evan. “IT providers are prime targets, especially during downturns when security investments lag, enabling widespread downstream breaches.”
Despite this, nearly three-quarters of small businesses lack enhanced cybersecurity measures. Many still don’t have basic protections against phishing, ransomware, or invoice fraud.
“Financial instability plays a critical role by forcing businesses to cut costs, often prioritising short-term survival over cybersecurity,” says Evan. “But this creates a dangerous cycle – weaker defences heighten the risk of attacks, which in turn worsen financial strain.”

The financial fallout from a cyberattack
A cyberattack can quickly escalate into a cash flow crisis, with businesses facing immediate expenses and delayed revenue at the same time.
Direct financial losses may include stolen funds, fraudulent transactions or regulatory fines. But the indirect costs – like operational downtime, data restoration, reputational damage and lost clients – often have the biggest long-term impact.
“While ransom payments or data recovery are often highlighted, subtler financial impacts are frequently overlooked,” says Evan. “Insurers may increase premiums or deny coverage if vulnerabilities were missed – leaving businesses exposed to legal, forensic or third-party costs that exceed policy limits.”
This financial strain can put working capital under pressure. That’s why cybersecurity planning must go beyond technical defences – it needs to include financial readiness too.
For businesses that remain operational but are feeling the cash flow pinch after a cyber incident, invoice finance can help eligible businesses unlock funds tied up in outstanding receivables to cover short-term gaps.
Beyond immediate cash flow gaps – and where there is suitable security in place – debtor finance or trade finance may provide additional flexibility to support ongoing operations while insurance claims are processed.
Why cyber security must include financial readiness
Cybercrime is now a daily operational risk for Australian SMEs – one with substantial costs and long-term consequences. For small businesses, even a short disruption in operations or delay in receivables can cause cash flow problems.
That’s why cybersecurity planning shouldn’t stop at firewalls and password policies. Managing cash flow during a crisis needs to be part of the conversation. Financial readiness is just as important as technical resilience.
When cash flow is vulnerable, business continuity is at stake. A strong financial buffer and a working capital strategy that can flex under pressure can make all the difference between short-term disruption and long-term damage.
