Top Cybersecurity Threats to Watch in 2025

Cybercriminals have become smarter than ever and found new ways to access your business systems. Emerging threats, such as AI-driven phishing, ransomware, and supply chain attacks, cause significant financial losses and disrupt operations. That is why businesses are focusing on cybersecurity.

The Australian Cyber Security Centre (ACSC) received more than 36000 cybercrime complaints in 2024 alone. Moreover, the cost of cybercrimes globally is expected to increase from $9.22 trillion in 2024 to $13.82 trillion by 2028.

We know these numbers are overwhelming, but you can prepare yourself by learning about the rising cybersecurity threats and steps to mitigate them in this blog.

1.      ‍AI-Driven Phishing

Emerging as the new face of deception in 2025, AI-generated phishing emails are relevant, persuasive, and grammatically correct. Cybercriminals use AI to increase the impact of phishing and gain unauthorised access to your confidential business data and systems.

These sophisticated attacks can bypass traditional detection methods and adapt to security measures in real time. They can also exploit human psychology, which means your employees may fall for the trick and share credentials or sensitive data.

How to Protect Your Business

• Invest in AI-powered security solutions to detect and respond to potential threats.
• Train your staff using deepfake and phishing simulations
• Use multi-factor authentication (MFA) for all accounts, especially for executive and privileged users

2.      Ransomware

Ransomware is a type of malware that disrupts your business operations, damages critical systems, and steals sensitive data. The global ransomware damage cost is projected to reach a staggering $265 billion by 2031.

Ransomware perpetrators have refined their malware payloads to encrypt the victim’s data and demand extortion. In fact, the attacks have become more targeted, focusing on critical infrastructure.

In many cases, large organisations feel helpless and end up paying hefty amounts. However, this may encourage criminals to continue to exploit security vulnerabilities. The government has introduced regulations like the Security of Critical Infrastructure Act and Essential Eight to mitigate these risks.

How to Protect Your Business

• Have off-site backups with a tested recovery plan in place
• Implement Endpoint Detection & Response (EDR) solutions
• Enforce security updates and patches to fill in the security gaps
• Train your staff on phishing and suspicious activities

3.      Supply Chain Attacks

Complex supply chains are vulnerable to cyberattacks, according to the World Economic Forum’s Global Cybersecurity Outlook 2025. These attacks compromise the interconnected systems before they reach the consumer, targeting smaller, less secure links in the supply chain to access more lucrative targets.

In simple words, cybercriminals target the third-party software provider, cloud service, or hardware manufacturer to infiltrate the customers. This means a single attack breaches multiple entities, leading to millions in losses per organisation across industries, like defence, healthcare, and aerospace.

How to Protect Your Business

• Implement strict risk management frameworks for third-party vendors
• Conduct security audits of your supply chain partners regularly
• Segment your network to limit the potential impact of a breach from a third party

4.      Internet of Things Attacks

IoT devices are helping businesses improve efficiency in different sectors, including logistics, agriculture, and healthcare. At the same time, cybercriminals are also finding gaps to target these connected devices and access valuable data. For instance, an IoT device may have a weak default security setting, unsecured network services, or outdated firmware.

How to Protect Your Business

• Change default passwords with unique credentials
• Update devices to patch vulnerabilities
• Segment IoT systems from your core business networks
