Australian businesses are targeted by a wide range of cyber threats, and many attacks focus directly on small and medium organisations because they often have weaker protections. The most common threats include phishing, where criminals send fake emails or messages to trick staff into clicking malicious links or giving away passwords. Business email compromise is another major threat, involving criminals gaining access to email accounts and redirecting payments or sending fraudulent invoices.
Ransomware remains one of the most damaging threats. It encrypts files and demands payment to unlock them, often shutting down operations for days. Malware and spyware can infect devices through downloads, websites or email attachments, giving attackers access to data or systems. Data breaches occur when sensitive customer, staff or financial information is accessed or stolen without permission.
Australian businesses are also increasingly facing supply chain attacks, where a smaller provider is compromised as a way to reach larger partners. Because the ACSC reports cyber attacks happening every few minutes across Australia, understanding these threats is essential for protecting finances, customer trust and operational continuity.
