The Top Cyber Security Threats Every Business Should Know

As companies increasingly rely on digital platforms for operations, communication, and data storage, they also become more vulnerable to cyber-attacks and data breaches. These attacks not only threaten the confidentiality and integrity of sensitive information; they pose significant security risks to a company’s reputation, operational stability, and bottom line. 

Recognising and understanding the various cyber security threats is the first step in tailoring your cyber security framework to better protect your business against these risks.

Cyber Security Threats: How Do They Impact Businesses?

Cyber security threats refer to any potential malicious attack that seeks to unlawfully access data, disrupt digital operations, or damage information. These threats can come in various forms and can target any part of a business’s digital infrastructure. 

No business, regardless of its size or industry, is immune to cyber security threats. Small businesses often think they’re not likely targets, but this misconception can leave them even more vulnerable. For larger enterprises, the sheer volume of data and the complexity of their digital systems can make them attractive targets for threat actors. 

The impact of a successful cyber-attack can be catastrophic, leading to financial losses, legal liabilities, erosion of customer trust, and long-term damage to a business’s reputation.

Top Cyber Security Threats Facing Your Business

Phishing Attacks

Phishing is a deceptive practice where cybercriminals send fraudulent emails or messages, mimicking legitimate sources, to trick individuals into revealing sensitive information such as passwords, credit card numbers, or company data. 

These attacks often rely on social engineering techniques to exploit human vulnerabilities, making them highly effective and dangerous. In January 2023, a Sydney man stole over $100,000 from 450 victims in an SMS phishing scam.


Short for “malicious software”, malware encompasses a wide range of harmful programs designed to infiltrate, damage, or disable computers and computer systems. This category includes viruses, worms, Trojans, and spyware, each with its unique method of attack and propagation.


Ransomware is a particularly insidious type of malware that encrypts the victim’s files or locks users out of their device, demanding a ransom payment for the decryption key or release. This cyber threat has seen a dramatic rise in prevalence and sophistication, targeting businesses of all sizes and sectors. 

The consequences of a ransomware attack can be devastating, leading to significant financial losses, reputational loss, and potential breaches of sensitive information. In February 2024, the Medusa ransomware group stole confidential customer data from Kadac Australia and demanded $100,000 to prevent the data from being leaked.

Insider Threats

Not all threats come from outside the organisation. Insider threats arise from current or former employees, contractors, or business associates who have inside information concerning the organisation’s security practices, data, and computer systems. 

These threats can be intentional (e.g., theft of data for personal gain) or unintentional (e.g., negligent handling of information), both of which can lead to significant security breaches. In early 2023, the Australian National Maritime Museum’s accounting system was accessed by a third-party IT contractor who changed the bank account details stored in the system to his own.

DDoS Attacks

Distributed Denial of Service (DDoS) attacks aim to overwhelm a system’s resources, making it unavailable to intended users. These attacks often target web servers of high-profile organisations such as banking, commerce, and media companies, causing significant disruption to operations and services.

Advanced Persistent Threats (APTs)

APTs are prolonged and targeted cyberattacks in which an intruder gains access to a network and remains undetected for an extended period. The purpose of these threats is usually to steal data rather than cause immediate damage. Their targeted nature and long-term presence make APTs particularly challenging to identify and eliminate.

Strengthening Your Cyber Security Framework

Regular Updates and Patch Management

One of the simplest yet most effective measures to enhance cyber security is to ensure that all software and systems are up-to-date. Cyber-attackers often exploit vulnerabilities in outdated software to gain unauthorised access to systems. 

Regularly updating and patching software, operating systems, and applications closes these security gaps and helps protect against known threats.

Employee Training and Awareness

People can be the weakest link in cyber security. Educating your workforce about the risks of cyber threats and training them to recognise signs of attacks, such as phishing emails, can significantly reduce the risk of successful breaches. 

Regular training sessions and awareness campaigns can foster a culture of cyber security mindfulness among employees.

Strong Access Controls

Implementing stringent user access controls ensure that only authorised individuals have access to sensitive information and critical systems. This includes enforcing strong password policies, using multi-factor authentication, and adhering to the principle of least privilege, where users are granted only the access necessary to perform their job functions.

Regular Data Backups

Maintaining regular backups of critical data is a vital defence mechanism, particularly against ransomware attacks. Backups should be stored securely, both on-premises and in the cloud, and tested regularly to ensure they can be restored in the event of a cyber incident – or natural disaster.

Incident Response Plan

Despite all precautions, cyber incidents can still occur. A well-defined and tested incident response plan enables businesses to respond swiftly and effectively to minimise the impact of a cyber-attack. 

The plan should outline roles and responsibilities, communication protocols, and steps for containment, eradication, and recovery.
