AI: The Double-Edged Sword of Cyber Attacks
Artificial Intelligence continues to revolutionise the way we approach cyber security, but it’s also empowering attackers with unprecedented capabilities. In 2025, we predict a significant rise in AI-driven cyber threats, from hyper-realistic phishing scams to automated vulnerability exploitation at scale. Deepfake technology, for example, is being used in phone scams and social engineering attacks, mimicking voices and appearances with unsettling accuracy to deceive victims. These attacks will be faster, more sophisticated, and harder to detect, leveraging AI’s ability to mimic human behaviour and analyse defences in real-time.
To counteract this, organisations must embrace AI-enhanced security solutions, invest in workforce training, and prioritise threat intelligence sharing. The battle against AI-powered attacks will demand a proactive and adaptive approach.

Ransomware Reloaded: The AI-Powered Threat
Ransomware attacks are expected to surge in 2025, with AI adding a dangerous new dimension. Attackers are increasingly leveraging AI to identify vulnerabilities more efficiently, automate their attacks, and tailor their tactics for maximum impact. Ransomware attacks can be supported through AI, which can adapt in real time, encrypting files faster or evading detection by mimicking legitimate processes.
The stakes are higher than ever, as these sophisticated attacks target not only businesses but also critical infrastructure and individuals. To combat this, organisations must invest in advanced threat detection systems, conduct regular security audits, and ensure robust incident response plans are in place to minimise downtime and financial loss.

Cyber Insurance 2025: Adapting to the AI-Driven Risk Landscape
Our next prediction for the top 5 cyber security threats of 2025 is that cyber insurance is expected to undergo significant shifts as the landscape of digital threats evolves. The market for cyber insurance is projected to grow to $22.5 billion over the course of 2025*, reflecting the increasing complexity and risks businesses face from cyber attacks.
One of the major factors influencing this change is the rapid growth in AI-driven threats. Insurers will be looking for businesses to demonstrate robust cyber resilience, particularly through proactive risk management practices such as implementing advanced cybersecurity measures and understanding the full scope of potential cyber exposures.
Coverage will likely expand beyond just ransom payments, with an increased focus on protecting against broader costs like business interruption, reputational damage, and legal repercussions.
As the sector matures, businesses will need to balance cost-effective measures with comprehensive protection, and insurers may offer discounts for companies that adopt stronger cyber security protocols, such as multi-factor authentication and endpoint detection.

Jailbreaking AI: Exploiting Language Models for Sensitive Data
In 2025, we anticipate a rise in the misuse of AI language models like ChatGPT through a technique known as jailbreaking. By exploiting vulnerabilities in the model’s safeguards, attackers can bypass restrictions and manipulate the AI into generating harmful content or aiding in illicit activities.
For instance, these jailbroken models might be used to craft highly convincing phishing emails, simulate conversations to extract sensitive information, or even provide step-by-step guidance for malicious actions. As AI becomes increasingly integrated into businesses and everyday life, it’s vital to establish clear usage policies, monitor for abuse, and stay updated on advances in AI safety to mitigate these risks.

Securing the Backbone: OT and Physical Security Threats to Critical Infrastructure
As we move into 2025, threats to Operational Technology (OT) and physical security are expected to rise significantly, particularly in sectors that rely heavily on critical national infrastructure (CNI). These infrastructures, such as energy grids, water treatment plants, and transportation systems, often use legacy systems that were not designed with modern cyber security in mind.
This makes them vulnerable to both cyber and physical attacks, especially as they become more interconnected with internet-enabled systems. The convergence of IT and OT increases the risk of cyber criminals or state-sponsored actors gaining access to these systems, potentially disrupting operations or even causing physical damage.
The Director of National Intelligence recently released a report where it found that “Iran-affiliated and pro-Russia cyber actors gained access to and in some cases have manipulated critical US industrial control systems (ICS) in the food and agriculture, healthcare, and water and wastewater sectors in late 2023 and 2024”.
Additionally, the dependence on third-party vendors and suppliers for essential services can introduce further vulnerabilities, creating a lucrative target for attackers. Given these challenges, enhancing the security posture of CNI has become a priority for governments and organisations worldwide, with increased collaboration and regulations to address these threats.

Looking Ahead: Navigating the Future of Cyber Security in 2025
As we look toward 2025, the cyber security landscape is set to become even more dynamic and complex. Emerging threats driven by AI, the convergence of IT and OT systems, and the growing reliance on cloud technologies will continue to challenge organisations across all sectors. Ransomware will evolve, aided by AI, while critical infrastructure faces mounting risks from both cyber and physical attacks.
The increased focus on cyber insurance, evolving regulations, and the growing importance of threat intelligence will shape how businesses approach security. Adapting to these changes requires a proactive mindset, robust security strategies, and a commitment to constant learning and adaptation to stay one step ahead of the ever-evolving cyber threat landscape.
With vigilance and innovation, organisations can better navigate these challenges and secure their futures in 2025 and beyond.
