Why SMEs Are Prime Targets for Cyberattacks
By Andrew McDowell
Many small and medium-sized businesses operate under a dangerous assumption: that hackers only go after large corporations. The reality is that SMEs are increasingly the preferred target for cybercriminals — precisely because they tend to have weaker defences.
The Numbers Don't Lie
In the 2024–25 financial year, 38% of Australian SMEs reported experiencing a cyberattack. In New Zealand, that figure was even higher at 59%. These are not isolated incidents — they represent a sustained and growing threat to businesses that often lack the dedicated IT security resources of large enterprises.
Why SMEs Are Targeted
They Are Easier to Breach
Large enterprises invest heavily in security infrastructure — firewalls, dedicated security operations centres, penetration testing programmes, and incident response teams. SMEs typically have none of these. A cybercriminal can often exploit a small business website in minutes using automated tools that scan for known vulnerabilities.
They Hold Valuable Data
SMEs hold customer data, payment information, and business credentials that are just as valuable as data held by larger companies. A customer's credit card number is worth the same regardless of whether it was stolen from a boutique or a bank.
They Are Entry Points to Larger Organisations
If your business provides services to larger clients — as many agencies and MSPs do — you may be targeted as a stepping stone. Compromising a supplier with weaker security can give attackers access to their clients' systems.
The Most Common Attack Vectors
- Outdated software and plugins: Unpatched content management systems and plugins are one of the most exploited vulnerabilities. An outdated WordPress plugin can provide direct access to your entire website backend.
- Weak or reused passwords: Credential stuffing attacks use leaked username and password combinations from previous breaches to try to access other accounts.
- Phishing: Deceptive emails that trick staff into revealing credentials or installing malware remain highly effective.
- Misconfigured servers: Exposed admin panels, open ports, and incorrect security headers invite automated attacks.
What You Can Do
The good news is that the majority of successful attacks on SMEs exploit known, preventable vulnerabilities. Regular vulnerability scanning — checking your website's public perimeter for misconfigurations, outdated software, and open attack surfaces — addresses the most common risks before they can be exploited.
Biz Secure Online was built specifically for this problem. Our automated scanning service monitors your website continuously, alerting you when vulnerabilities appear so they can be fixed before attackers find them.
