The digital landscape is constantly evolving, both for better and worse, with an increasingly sophisticated array of cybersecurity threats to SMEs in Ireland in 2024. This heightened level of risk when operating online means that robust security measures and increased vigilance are crucial to protect the livelihood and reputation of business owners around the country.

Among the most pressing cybersecurity concerns looming over these enterprises are ransomware attacks, phishing scams, insider threats, supply chain attacks, business email compromise, vulnerability exploitation, and DDoS attacks. In this article, we explore these threats in detail and provide actionable strategies to mitigate them and safeguard business operations in the process.

 

7 cybersecurity threats to SMEs in Ireland

 

Several dangers are lurking in the digital shadows of every organisation, just waiting to rear their harmful heads. Some are unfortunately becoming quite common occurrences, and others have made an unwelcome appearance in more recent months and years.
Gaining an awareness of these threats is key to mitigating the potential risks they present. Here is all you need to know…

 

Cybersecurity threat #1 – Ransomware attacks

 

Ransomware remains a serious threat, with cybercriminals increasingly targeting SMEs that are perceived as having weaker defences than their larger and more developed counterparts.

These attacks involve malicious software that encrypts a company’s data, rendering it inaccessible until a ransom is paid. The financial and operational impact of such attacks can be devastating, often crippling businesses for extended periods.

A notable example of this is the 2021 cyberattack on the Health Service Executive (HSE). Since this attack, close to 500 legal proceedings have been taken against the HSE, showcasing just how detrimental this type of cybercrime can be.

 

Cybersecurity threat #2 – Phishing scams

 

Second on the list are phishing scams, which have evolved significantly since they first emerged, becoming more targeted and convincing.
Spear phishing, in particular, involves tailored attacks that trick employees into disclosing sensitive information or downloading malware.

These attacks exploit human psychology, making them difficult to detect and prevent without thorough employee training and robust security protocols.

 

Cybersecurity threat #3 – Insider threats

 

Insider threats pose a major risk to businesses, stemming from both malicious insiders and careless employees. Malicious insiders may intentionally leak sensitive information or facilitate cyberattacks, while negligent employees can inadvertently create vulnerabilities through poor cybersecurity practices.

Mitigating these risks requires a combination of stringent access controls, continuous monitoring and comprehensive employee education on digital security and best practices.

 

 

Cybersecurity threat #4 – Business Email Compromise (BEC)

 

Business Email Compromise (BEC) fraud involves attackers impersonating company executives or trusted partners to deceive employees into transferring funds or divulging confidential information.

These scams are highly targeted and can lead to substantial financial losses, particularly for the small firms that often fall victim to such attacks, as was witnessed in recent months with a spate of incidents in Ulster.

Implementing robust email authentication and verification processes is an essential step in the defence against BEC attacks.

 

Cybersecurity threat #5 – Supply chain attacks

 

Another pressing cybersecurity concern, and one that is very similar to BEC fraud, comes in the form of supply chain attacks, which are designed to exploit vulnerabilities in third-party suppliers to gain access to a business’s network.

Because small and medium businesses often rely on a diverse array of suppliers, they are particularly vulnerable to these attacks.

Ensuring that all partners adhere to stringent cybersecurity standards is crucial in mitigating this risk.

 

Cybersecurity threat #6 – Vulnerability exploitation

 

Vulnerability exploitation refers to the practice of cybercriminals actively seeking out and exploiting known weaknesses in software and hardware. Businesses can be exposed to this threat for several reasons, such as using outdated software, or once again, human error exposing vulnerabilities.

Regularly updating and patching systems is critical to closing these security gaps. Additionally, SMEs must prioritise vulnerability management to prevent attackers from exploiting weaknesses in their digital infrastructure.

 

Cybersecurity threat #7 – DDoS (Distributed Denial of Service) attacks

 

DDoS attacks aim to overwhelm a business’s online services, causing significant disruption and potential financial loss. These attacks have become more accessible to cybercriminals, making them a prevalent problem.

Developing strong network defences and DDoS mitigation strategies is vital to maintaining service availability and protecting business operations.
