Ransomware continues to be one of the most damaging cyber threats facing organisations. What has changed is the introduction of artificial intelligence.

Cyber criminals can now use AI to automate reconnaissance, identify vulnerabilities and tailor attacks to specific organisations. Rather than launching broad campaigns, attackers can focus on businesses that appear most likely to pay. AI also enables criminals to create more convincing phishing emails, automate attack workflows and identify security gaps faster than ever before.

Unlike ransomware, Advanced Persistent Threats operate quietly. APTs often involve highly organised criminal groups or nation-state actors who gain access to systems and remain undetected for weeks or even months. During this time, they gather intelligence, steal sensitive information and identify high-value targets within the organisation.

Many businesses only discover an APT after significant damage has already occurred.

Businesses are more connected than ever. Your organisation may have strong internal security controls, but what about your software providers, suppliers or business partners?

Supply chain attacks exploit trusted relationships. Attackers compromise a third party and use that access to infiltrate downstream organisations. Several of the largest cyber-attacks in recent years have originated through trusted software providers and service partners.

Your security posture is only as strong as the weakest link in your ecosystem. A compromised supplier can expose your organisation even when your internal security controls are robust.

A data breach is more than a technical issue — it is a business crisis. Breaches can begin with something as simple as a weak password, a lost laptop or an employee clicking a malicious link. Once attackers gain access, they can steal customer records, financial information, employee data or commercially sensitive information.

For organisations operating in Ireland and the EU, breaches can also trigger GDPR reporting obligations and regulatory scrutiny.

Today's workplaces contain far more than laptops and servers. Printers, CCTV systems, smart meeting room devices, access control systems and connected sensors all create additional attack surfaces.

Unfortunately, many IoT devices are deployed with default passwords, outdated firmware or minimal security controls — and these devices are frequently overlooked during security reviews. Attackers often target IoT devices because they provide an easy entry point into otherwise secure networks. A single vulnerable device can create a pathway to wider network compromise.

We are entering an era where seeing is no longer believing. Artificial intelligence now enables criminals to create realistic voice recordings, video calls and messages that convincingly impersonate executives, suppliers and employees.

Deepfake-enabled fraud is growing rapidly and can be used to authorise payments, manipulate staff or gain access to sensitive information. Traditional awareness training alone may not be enough — employees may struggle to distinguish between genuine and AI-generated communications.

Cloud platforms have transformed the way businesses operate. Solutions such as Microsoft 365, SharePoint, Teams and OneDrive provide flexibility, collaboration and scalability. However, cloud adoption also introduces new risks.

Simple configuration mistakes, excessive permissions or unsecured data repositories can expose sensitive information to attackers. Many breaches occur not because cloud platforms are insecure, but because they have been configured incorrectly. A single misconfiguration can expose critical business data within minutes — and attackers actively scan cloud environments looking for these opportunities.

Businesses should understand that cloud security is a shared responsibility, not something that can be delegated entirely to the provider.
