Cyber Attacks Expose Growing Risks To Africa Healthcare Systems And Sensitive Patient Data

World Health Organisation (WHO) director-general Tedros Adhanom Ghebreyesus noted that the digital transformation of healthcare, combined with the high value of health data, has made the sector a prime target for cybercriminals, commenting that “At best, these attacks cause disruption and financial loss.

“At worst, they undermine trust in the health systems on which people depend, and even cause patient harm and death.”

Fragile

Recent attacks have exposed the fragility of Africa’s medical infrastructure.

In May 2025, Mediclinic Southern Africa was hit by a cyber extortion attack, compromising sensitive HR data.

Later in 2025, Lancet Laboratories faced a regulatory penalty for failing to notify patients about data breaches under South Africa’s PoPIA law, while a ransomware strike on the National Health Laboratory Service disrupted blood test processing nationwide, delaying critical care for millions.

M-Tiba, a Kenyan digital health platform managed by CarePay and backed by Safaricom, suffered a significant cyberattack and data breach in late 2025, while earlier this year Pharmacie.ma, a Moroccan pharmaceutical platform, was reportedly the target of an alleged data leak incident that allegedly involved the unauthorised export of a customer database.

And recent research indicates that Nigeria’s private healthcare sector is now one of the most targeted on the African continent, with attacks increasing at an alarming rate.

Many incidents also go unreported, as hospitals and healthcare facilities rarely disclose them publicly, yet these incidents are not isolated, with ransomware dominating the threat landscape.

Africa’s healthcare sector is heavily targeted by cybercriminals, with healthcare organisations facing an average of 3,575 weekly attacks in 2025, a 38% surge from the previous year, with encryption of patient data, temporary loss of access to hospital systems and the risk of data appearing on the dark web cited as potential impacts.

Easy target

The healthcare industry in Africa, particularly in the public sector, is working with legacy systems, fragmented infrastructure, and underfunded IT teams, all of which combine to make the sector an easy target for unscrupulous bad actors.

Many medical institutions are adopting open-source AI tools for diagnostics and patient management. While cost-effective, these platforms often lack enterprise-grade security, leaving sensitive data exposed.

Combined with fragmented storage of paper and electronic patient records – often unencrypted and scattered across multiple systems – the risk of breaches multiplies.

Hospitals and healthcare facilities cannot afford downtime. Every minute offline risks lives, making them more likely to pay ransoms in an attempt to regain control of their systems.

Cyber insurers indicate that in two of five cases of a ransom being paid, data and operations still cannot be recovered.

Additionally, in instances where some or all of the seized data is recovered after paying a ransom, the attacker goes on to request further payments.

Medical records are also a premium target for cybercriminals.

In the USA, researchers found that patient records, insurance details, and research data fetch premium prices on the dark web – up to 10 times higher than financial data, according to cybersecurity analysts.

A single stolen medical record can sell for $260–$310, compared to $30–$50 for a credit card, because unlike credit cards, medical records never expire, and medical information cannot be easily changed, making it useful for years.

Medical records frequently include personal identifiers, insurance details, and sometimes biometric data, enabling identity theft and fraud, while criminals use medical data for fake insurance claims, prescription fraud, and targeted scams.

Cybersecurity needs to be embedded into every technology implementation.

This should be a key priority, especially with sensitive medical data and operations.

Digital lifeline

As Africa’s healthcare systems digitise and embrace AI, protecting the digital lifeline must become as critical as protecting the physical one.

Key steps can secure healthcare organisations and facilities, such as laboratories and diagnostic services’ systems.

Include cybersecurity in your resilience planning

Medical professionals and healthcare facilities often prioritise the resilience of physical capabilities.

Power backups, multiple devices, equipment failure, and a standby roster in the event of a practitioner being unavailable are all practices that save lives.

Equally, cybersecurity and safeguarding online systems need to be built into the overall resilience planning of medical facilities and services.

Investing in cybersecurity technology that can quickly identify and contain attacker activity before it leads to system downtime or data theft can save lives.

Having a response plan that is practised and maintained in the event of a cyber breach and ensuring strong data backups could mean the difference between a total failure of health services or a minor incident.

Ensuring incident response plans are aligned with local compliance laws, such as South Africa’s PoPIA, and Kenya and Nigeria’s Data Protection Acts, is critical for healthcare providers to meet both their resilience and compliance objectives.

Prepare for AI-driven attacks

Threat actors are increasingly exploiting the interconnectedness of modern software ecosystems and operational structures to conduct malicious activity, so regular auditing of third-party integrations, especially those involving AI or cloud services, is critical.

Adversaries are using AI to scale and tailor operations, with AI-driven phishing being 4.5x more effective than traditional phishing.

However, in equal measure, AI is transforming cyber defence – it automates response and containment, detects threats faster and more accurately, and identifies detection gaps and adapts to attacker behaviour.

Healthcare organisations should invest in AI-driven threat detection for faster response and anomaly detection, and must also take steps to secure AI models and data pipelines by implementing robust access controls, vulnerability scanning, and regular patching for open-source tools.

Strong identity practices

As both patients and medical professionals start accessing patient records digitally, strong means of identification, verification and authentication are critical.

The Microsoft Digital Defense Report 2025 notes that the abuse of valid accounts is a frequent occurrence, with malicious actors gaining access to user credentials (usernames and passwords) and using them to infiltrate systems without triggering traditional security alerts.

Therefore, organisations must deploy phishing-resistant multifactor authentication (MFA) and conditional access to strengthen user defences.

Invest in people and skills

People are at the heart of robust cybersecurity measures, so it is vital to train staff against common tactics such as phishing, which is the most common entry point for attackers, and apply role-based access controls for both clinical and research data to prevent privilege misuse.

Cybersecurity is no longer an IT issue – it’s a patient safety issue.

Healthcare services and providers must treat digital resilience with the same urgency as infection control.

By investing in comprehensive cybersecurity strategies and leveraging AI-powered defences, Africa’s healthcare sector can position itself as a crucial front line against emerging threats and help build stronger, more resilient digital ecosystems.
