From Phishing to Ransomware: The Most Common Cyber Attacks Facing the UK

The UK’s digital economy continues to grow but so too does the threat posed by cyber crime. In recent years, cyber attacks have become more frequent, more sophisticated and significantly more costly. Businesses across all sectors—from retail and finance to public infrastructure—are under near-constant digital assault. Among the most common threats are phishing and ransomware, which dominate the cyber threat landscape. Understanding these threats is vital to protecting both organisational resilience and national security.

The UK’s Most Common Cyber Attacks
*

Phishing: The Most Prevalent Threat

Phishing remains the most widespread cyber attack method. In 2025, 93% of UK businesses and 95% of charities that reported a cyber incident identified phishing as the primary vector. These attacks typically rely on deception—posing as trusted individuals or institutions to trick users into disclosing credentials, installing malware or revealing sensitive data.

The sheer frequency of phishing means that businesses are often targeted multiple times. On average, affected UK organisations experienced 30 cyber attacks of any kind in the past 12 months, many involving phishing campaigns.

Ransomware: Rapidly Rising and Highly Disruptive

Ransomware is one of the fastest-growing and most damaging cyber threats. In 2025, the percentage of UK businesses experiencing ransomware doubled to 1% (roughly 19,000 businesses) up from less than 0.5% in 2024.

Major UK retailers and other high-profile organisations have been brought to a standstill by ransomware attacks with consequences ranging from data loss and operational downtime to severe financial loss. Ransom demands are increasing in both volume and sophistication.

The average cost to recover from a cyber attack is now around £21,000 per incident, but large-scale attacks can result in exponentially higher expenses. The wider economic burden of cyber crime in the UK is estimated at a staggering £27 billion annually.

Data Breaches and Business Email Compromise

Alongside phishing and ransomware, data breaches and business email compromise (BEC) are on the rise. These threats often involve malware or the exploitation of third-party vendor vulnerabilities (supply chain attacks).

High-profile breaches in 2025 alone have exposed billions of user credentials and confidential records. UK organisations have been among the hardest hit, leading to financial loss, reputational damage and regulatory scrutiny.

*

DDoS (Distributed Denial of Service) Attacks

DDoS attacks aim to shut down services by flooding systems with malicious traffic. These attacks have grown in both scale and frequency in 2025.

Retailers, financial service providers and public sector organisations are frequent targets, with attackers seeking to disrupt critical services, extort ransom payments, or distract IT teams from more damaging intrusions.

*

Cyber-Facilitated Fraud

Cyber-enabled fraud remains a persistent threat, affecting approximately 3% of UK businesses in the past year—around 40,000 organisations.

These attacks often involve social engineering, phishing, or manipulation of digital systems to commit fraud. The average financial loss per business is estimated at £5,900 or £10,000 when excluding organisations that reported no financial damage.

Why the UK Is an Attractive Target

Several factors contribute to the UK being a primary target for cyber attacks:

• Digital Maturity: The UK’s high adoption of digital platforms and interconnected systems expands the potential attack surface for cyber criminals.
• Valuable Sectors: Retail, finance and infrastructure provide high-value targets for data theft and disruption.
• Skills Gap: A continuing shortage of cybersecurity professionals leaves many organisations vulnerable due to inadequate prevention and response capabilities.

National and Organisational Responses

Government Action

The UK Government has taken steps to improve national resilience through legislation like the Cyber Security and Resilience Bill (2024). This bill introduces stricter reporting requirements and aims to prohibit public bodies from paying ransoms.

*

Corporate Preparedness

Despite the rising threat, many businesses remain unprepared. Only 22% have formal incident management plans in place, and fewer than a third have carried out cyber risk assessments in the past year.

*

The Role of Awareness and Education

Cybersecurity awareness among staff is a critical yet inconsistently applied defence. Regular training, phishing simulations and internal policy updates are all vital but not yet standard practice across the UK.

The Road Ahead: Strengthening UK Cyber Resilience

To reduce the impact of cyber threats, the UK must continue to invest in both public and private sector cybersecurity.

This includes:

• Expanding cybersecurity education and closing the digital skills gap
• Mandating comprehensive risk assessments and response plans
• Promoting public-private collaboration to share threat intelligence
• Encouraging a proactive, rather than reactive, approach to cyber risk

Phishing, ransomware, data breaches and fraud are not isolated risks—they are now everyday realities for UK businesses. As cyber criminals evolve, so too must the defences. With improved awareness, robust infrastructure, and decisive action from both government and industry, the UK can better safeguard its digital economy and critical
