How Cyber Threats Are Changing - And What Your Clients Can Do About It

Last Updated 16 September 2025

Businesses in Europe and across the globe face an increasingly volatile digital threat landscape. Cybercriminals are using new tactics to launch attacks – and harnessing advances in technology to make those attacks happen faster.

For example, generative artificial intelligence (AI) will continue to make elements of cyberattacks more effective and efficient, which will increase the frequency and intensity of cyber threats in the coming years. Strong defences are needed in response: A recent report from Cyber Ireland said businesses are responding by allocating more than 70% of their cybersecurity budget to the use of generative AI to detect and counter threats. Meanwhile, regulations including NIS2, DORA and the Cyber Resilience Act are imposing tighter security requirements on businesses in critical sectors in Ireland and the rest of the EU.1

“In the current cyber threat environment, monitoring the shifting tactics of cybercriminals is a full-time job,” said Matthew Waller, Head of Cyber at Travelers Europe, who moderated a recent webinar about how businesses can improve their cyber resilience. “When a business partners with us to manage their evolving cyber risks, they get a playbook for managing a cyber incident. Just as importantly, they gain peace of mind, knowing they are enhancing their cyber resilience, as well as time and energy to focus on running their business.”

The Threats Facing Irish Businesses Today

The global cyber threat landscape has seen a marked rise in activity in recent months, particularly in ransomware and phishing-related attacks. Ransomware incidents surged 35% in the first quarter of the year over the previous quarter, though there has been a trend toward smaller payments in recent months, according to the Travelers Q1 Cyber Threat Report. Several factors are likely driving the change in payment size, including increased cyber security awareness, improved backups lessening the impact of data breaches, and greater law enforcement efforts disrupting ransomware operations. Victims are also becoming more adept at negotiating ransom amounts, often paying less than the initial demand.2

Business email compromise remains a major threat as well. “Back in 2023, about 39% of all our claims involved either business email compromise or phishing attacks in some way,” said James Doswell, Senior Risk Management Consultant at Travelers Europe. “Frustratingly, many of these compromises could easily have been avoided, with 42% of the victims lacking multi-factor authentication on their email access. Business email compromise still accounts for a large portion of our claims, which underscores how organisations across sectors are leaving themselves vulnerable to attack.”

Smarter Tactics, Faster Attacks

One of the most notable trends across the cyber threat landscape is the evolution of ransomware tactics. Cybercriminals are increasingly relying on brute force attacks, social engineering, and the exploitation of older, unpatched vulnerabilities. The ransomware ecosystem itself is fragmenting, with once-organised groups splintering, partly due to law enforcement pressure. This shift has led to the rise of less predictable, lone-wolf actors and disorganised cyber gangs. These groups often lack professionalism, which can make their attacks harder to anticipate and neutralise.

AI-driven threats are an emerging concern as well. Threat actors are using AI to enhance their capabilities by, for example, creating polymorphic malware that can adapt to evade detection. Increasingly, AI is also being used to circumvent security controls and in highly credible deepfake technologies. These deepfakes, particularly when used in social engineering schemes, pose a significant threat. One $25 million fraud incident occurred when a CFO was impersonated using deepfake technology.3 As these tools become more accessible, the risk of high-stakes impersonation fraud is expected to rise.

Automation is accelerating the pace of all of these attacks. Readily available scripts and tools now enable attackers to bypass security controls with alarming speed. Moreover, a trickle-down effect is occurring, where advanced tactics used by elite threat actors are being adopted by less sophisticated groups. This widespread replication of successful attack methods increases the overall risk for organisations, regardless of size or sector.

How to Prepare a Response to Cyber Attacks?

While the retail sector has drawn media attention due to high-profile breaches like the recent attack on Marks & Spencer, organisations of all sizes particularly in the legal, construction, healthcare and manufacturing sectors are targets.4 These industries often hold valuable data and operate complex supply chains, making them attractive to cybercriminals. The financial repercussions of such attacks can be severe. It’s critical that businesses know how to minimise their risks of an attack – and if one does occur, deploy an incident response that helps contain financial and reputational damage.

To help businesses mitigate their evolving risks, they can implement phishing-resistant MFA, develop a robust vulnerability management programme, and maintain tested, offline backup systems. Organisations can further improve their resilience using endpoint detection and response (EDR) solutions with 24/7 monitoring to swiftly identify and contain threats.

Why Cyber Insurance Still Matters

Beyond technical controls, organisations can fortify their protection with proactive risk management, including cyber insurance and pre-incident planning. The underwriting process alone can identify needed safeguards that can preserve business continuity following a cyber incident. Without cyber insurance – or appropriate cyber protection for their specific risks – a business is in a precarious position after a breach: it can easily end up scrambling for support from lawyers, IT experts and a range of other professionals to contain the problem – and remain offline until it can secure its systems.

“Having appropriate cyber insurance helps an organisation anticipate the potential consequences of a breach and put protections in place that minimise their risks,” said Waller. “At Travelers, we’re providing threat intelligence 24/7. Our scanning technology allows us to monitor our clients, identify any vulnerabilities in the moment, and engage with them as needed. We can help them contain damage when minutes count.”

Cyber threats are evolving rapidly in scale, sophistication and scope. These risks call for businesses to have a multi-layered, proactive defence strategy. By staying informed and investing in the right protections, organisations can significantly reduce their exposure and enhance their ability to respond to whatever threats are ahead.
