Top 8 cybersecurity threats facing UK businesses

In today’s digital-first world, UK businesses face increasing risks from cyber threats. According to the UK Government’s Cyber Security Breaches Survey 2023, 32% of UK businesses reported experiencing a cyber attack within the past year. These threats can cause financial losses, reputational damage, and legal repercussions. In this article, we’ll examine the top cybersecurity threats affecting UK businesses and provide actionable strategies to mitigate them.

1. Phishing attacks

Phishing is one of the most common forms of cyber attacks, targeting employees with fraudulent emails to steal credentials or financial information. In 2023, 80% of UK businesses flagged phishing as a primary concern.

How to defend: Educate employees to recognise phishing attempts, use email filters, and conduct phishing simulations. For more tips, visit our blog on preventing common cyber attacks.

2. Ransomware

Ransomware attacks encrypt a business’s critical data and demand payment to restore access. These attacks cost UK businesses millions annually and often result in downtime and data loss.

How to defend: Maintain regular data backups, implement robust endpoint security, and keep systems updated. Consider managed cybersecurity services to strengthen your defences.

3. Insider threats

Insider threats involve employees, contractors, or partners misusing their access to systems and data. These threats account for 34% of data breaches globally.

How to defend: Implement access controls, monitor user activity, and regularly review permissions. Managed services from DarkShield can help manage insider risks.

4. Distributed denial of service (DDoS) attacks

DDoS attacks flood networks with traffic, causing disruption and downtime. In 2022, such attacks increased by 20% in the UK.

How to defend: Use DDoS protection services, content delivery networks (CDNs), and conduct regular penetration tests to identify vulnerabilities.

5. Malware

Malware is malicious software designed to disrupt operations, steal data, or gain unauthorised access. Common types include viruses, worms, and trojans.

How to defend: Use reliable antivirus solutions, regularly update systems, and perform vulnerability assessments to identify security gaps.

6. Weak passwords and credential theft

Weak passwords remain a significant vulnerability for businesses, often exploited through brute force attacks or credential stuffing. A staggering 61% of breaches involve stolen or weak credentials.

How to defend: Enforce strong password policies, implement multi-factor authentication (MFA), and use password managers to secure credentials.

7. Supply chain attacks

Cybercriminals exploit vulnerabilities in third-party vendors or suppliers to access business systems. The UK has seen an increase in these attacks targeting small and medium-sized enterprises.

How to defend: Vet third-party suppliers for security measures, use contracts to enforce compliance, and monitor external integrations. Learn more about supply chain security on our page about compliance and risk management.

8. Compliance failures

Non-compliance with cybersecurity laws like GDPR or the Data Protection Act 2018 can result in significant fines and legal action. Many businesses fail to stay updated on regulatory requirements.

How to defend: Regularly review your compliance status and seek expert advice. Visit our guide to cybersecurity laws for UK businesses for more details.
