The rise of ransomware in the UK

The vast majority of UK businesses now recognise ransomware as one of the most severe cyber threats they face. According to the National Cyber Security Centre (NCSC), recent cyber security breaches have shown that cyber attackers are no longer just targeting large businesses – small businesses, public sector organisations, and even service providers have become prime targets.

Ransomware gangs and groups such as Scattered Spider exploit vulnerabilities across multiple platforms, often using phishing emails, social engineering, or compromised supply chains to gain access to sensitive data. Once inside, attackers can trigger a data breach, disrupt systems, and leak personal data, intellectual property, or other sensitive information for financial gain.

Which sectors are under attack?

While all UK organisations are at risk, certain business sectors have become particularly attractive to cyber criminals:

• • Manufacturing industry – A lucrative target because of reliance on operational technology, often with limited resilience.

• • Retail sector – Heavy adoption of contactless payments makes this sector vulnerable to fraud and data leaks.

• • Public sector organisations – Government departments, healthcare, and local councils store vast amounts of personal data, making them frequent victims.

• • Service providers and supply chains – Attackers exploit the security risks of interconnected organisations to infiltrate multiple partners at once.

For attackers, these sectors represent not just one breach, but opportunities to exploit resources and systems at scale.

Why senior management must take action

In many cases, senior management underestimates the scale of cyber crime and assumes their business will not be a target. Yet recent attacks prove otherwise. Whether it’s a co-op supermarket outage, disruption to manufacturing production lines, or theft of sensitive data from public sector systems, attackers adapt quickly to exploit weak defences.

Leaders must remain vigilant, treat cyber incidents as business risks, and ensure that both technical and strategic measures are in place to protect their organisation.

Key steps to stay ahead of cyber security breaches

Every business, regardless of sector or job role, should adopt a proactive cyber security strategy. Some critical measures include:

• • Multi-factor authentication (MFA) – Implement across multiple platforms to secure access.

• • Regular training to spot phishing attacks and phishing emails.

• • Following NCSC guidance to strengthen defences against hackers.

• • Testing incident response services so your team can respond quickly to an active cyber incident.

• • Protecting sensitive data and intellectual property through encryption and restricted access.

These measures reduce security risks and help organisations stay one step ahead of attackers.
