Healthcare organisations across the UK and beyond are under unprecedented pressure from cyber criminals in 2025. According to industry research, over 90 per cent of healthcare providers experienced some form of cyberattack last year, with the cost of the most severe incidents reaching millions of pounds.

Patient records, clinical data and critical hospital systems are highly valuable to attackers, making healthcare a prime target. Limited budgets and complex digital supply chains only increase the risks. To protect patients and maintain trust, healthcare leaders must understand the key cybersecurity threats emerging this year.

Ransomware Evolves

Ransomware remains the most damaging threat. Criminal groups are now using two advanced tactics. First, they target cloud backups and archived data to cripple recovery efforts. Secondly, they exploit weak identity and session controls to gain access to live systems before launching a carefully timed attack. The result can be catastrophic - loss of patient data, cancelled procedures and significant regulatory fines.

Cloud Misconfigurations and Supply-Chain Risks

As more healthcare services move to the cloud, misconfigured environments and poorly secured third-party applications are becoming prime entry points. Attackers look for simple errors, such as publicly exposed storage buckets or outdated software components. With healthcare relying heavily on suppliers, every vendor relationship must be assessed for security weaknesses.

Automated Bot Traffic

Bad bots are increasingly sophisticated, imitating human behaviour to bypass basic defences. These automated tools attempt credential-stuffing attacks on patient portals, scrape sensitive health information and can overwhelm systems to cause denial of service.

AI-Driven Phishing

Artificial intelligence and large language models are enabling criminals to create highly convincing phishing emails and messages. These attacks use personal details gleaned from social media and past breaches to trick staff into revealing credentials or clicking malicious links. One slip can lead to unauthorised access to entire clinical networks.

How Healthcare Organisations Can Respond

To counter these threats, healthcare providers should take a proactive, layered approach:

Strengthen identity and access management by enforcing multi-factor authentication, implementing zero-trust policies and applying strict session controls.

Secure cloud environments using automated tools to detect misconfigurations, and require a clear software bill of materials from every supplier.

Improve monitoring and detection with AI-driven analytics that identify abnormal traffic and bot behaviour in real time.

Educate staff with regular phishing simulations and clear reporting channels to reduce human error.

Build cyber resilience through robust backup, incident response and disaster-recovery planning so that critical services can continue even if an attack succeeds.
