Cybersecurity in healthcare isn’t just a matter of regulation it’s a matter of care. For hospitals, clinics, and healthcare providers across Australia, digital threats aren’t confined to the IT department. They can directly impact patient treatment, staff workflow, and community trust. This blog explores how growing cyber risks are affecting the healthcare sector, what can be done about it, and why a strategic, managed approach is becoming essential.
Understanding the cybersecurity realities in healthcare
Healthcare systems are highly connected and data-rich which makes them attractive to cybercriminals. And with outdated infrastructure still common in many organisations, threat actors often don’t have to try too hard to find a way in.
Rising breach volumes
Healthcare continues to top the list of reported data breaches in Australia. The Office of the Australian Information Commissioner (OAIC) reported that health service providers experienced more breaches than any other sector.
What’s being targeted?
Attackers are focusing on:
- Electronic medical records (EMRs)
- e-Prescription platforms
- Internal email systems
- Admin platforms and billing software
- Diagnostic or treatment-related devices (e.g. connected imaging tools)
When these systems go down, it’s not just an IT inconvenience it’s a delay in care delivery, access to medical history, or the ability to communicate with patients.
Real-world impact: MediSecure and St Vincent’s Health
The risks are no longer hypothetical. Two major breaches in Australia’s healthcare system, MediSecure and St Vincent’s Health Australia, show how far-reaching the consequences of a cyberattack can be.
MediSecure
A cyberattack on e-prescription provider MediSecure exposed 12.9 million health records. These included sensitive prescription histories and raised serious concerns about patient privacy and digital trust.
Although MediSecure was not a direct care provider, the attack caused ripple effects across the country. As a core part of the electronic prescription supply chain, its disruption affected general practices and pharmacies nationwide. The Department of Home Affairs launched an investigation and reinforced the urgency of strengthening protections across digital healthcare systems.
“The Australian Government takes the protection of Australians’ personal information seriously. We continue to work with MediSecure to determine the full extent of the incident.” — Department of Home Affairs
St Vincent’s Health
St Vincent’s Health Australia, one of the country’s largest not-for-profit health and aged care providers, also experienced a significant cyber incident. The attack disrupted operations across hospitals, aged care services, and pathology labs.
While specific details of the breach were not disclosed, the broader concern was the potential impact on hospital systems. A system compromise can delay treatment, disrupt diagnostics, and limit access to critical patient data. In complex healthcare environments, even brief system outages can lead to serious clinical consequences.
“We immediately took steps to secure our systems and engaged cyber specialists to investigate. Our focus remains on the continuity of care for those we serve.” — St Vincent’s Health Australia.
How cyber incidents impact patient trust and compliance
The examples of MediSecure and St Vincent’s Health show how quickly a cyber incident can escalate into a broader operational and reputational crisis. They also highlight three key threat types that every healthcare organisation must understand and prepare for: data breaches, ransomware, and insider threats.
Data breaches erode trust and expose legal risk
Healthcare data is among the most sensitive information any organisation can hold. A breach involving electronic medical records, Medicare details or prescription history isn’t just a compliance issue. It undermines the core relationship between patients and providers.
Under Australia’s Privacy Act 1988 and the Notifiable Data Breaches scheme, healthcare organisations are required to notify both the OAIC and affected individuals when personal data is exposed. This means a breach can quickly become a public event, drawing media attention and requiring formal crisis management. Trust, once lost, is difficult to regain, especially in sectors like aged care, mental health or fertility services where privacy is paramount.
Ransomware can halt care delivery
Ransomware attacks are not only about data loss. They’re about disruption. When a hospital or clinic is locked out of its systems, clinicians may be unable to access critical patient records, diagnostic results or prescription histories. This slows response times, delays treatment and can affect patient outcomes.
In some cases, ransomware groups extract data before encryption and threaten to leak it publicly. This tactic not only increases pressure to pay a ransom but also raises serious privacy and reputational concerns. For healthcare providers, the cost of downtime and recovery can be significant, but the impact on patient safety is even more critical.

Insider threats are common and preventable
While external attacks often make the headlines, many healthcare breaches originate from within. A mistyped email address, weak password practices or unauthorised access to patient files can all trigger a reportable breach. According to the OAIC, nearly one-third of breaches in the healthcare sector are caused by human error (OAIC statistics).
Staff don’t need to be malicious to create risk. Most insider incidents result from a lack of training, unclear processes or access controls that haven’t been properly enforced. That’s why internal awareness and governance are just as essential as external defences.
The strategic benefit of managed IT and cybersecurity support
A managed approach allows healthcare organisations to consolidate technology, security, and continuity planning into a single operational stream. It also ensures that expertise is available when and where it’s needed, without overburdening internal staff.
What’s included?
Working with a MSP is not enough, you need an MSP who also offers managed security services and remediation options that suit the health vertical.
Does your MSP have the following?
- Traditional Managed Services (TMS): IT infrastructure support, helpdesk, cloud management, and hardware lifecycle services
- Managed Security as a Service (MSaaS): Security operations centre (SOC) monitoring, threat detection and response, vulnerability management
- Business Continuity and Disaster Recovery (BCDR): Backup management, disaster simulations, and response playbooks
These services together provide a strong foundation for:
- Early threat detection
- Fast and reliable recovery from incidents
- Reduced downtime
- Improved regulatory compliance
How it works in practice
Let’s say a phishing email successfully compromises a staff member’s account. A managed security provider can:
- Detect the anomaly in user behaviour via SOC monitoring
- Isolate affected systems
- Initiate pre-planned containment and remediation protocols
- Review logs to assess what, if any, data was accessed
- Provide reporting for OAIC compliance
This kind of coordinated response is nearly impossible without specialised tools, processes, and dedicated teams.
Compliance is the baseline not the benchmark
Healthcare organisations must meet legal requirements under Australia’s Privacy Act and, where applicable, My Health Record regulations. But the goal should go beyond compliance.
A managed security program can support:
- Regular privacy impact assessments
- Encryption of patient data at rest and in transit
- Role-based access controls for EMRs and platforms
- Audit logs and compliance-ready reporting
It also helps prepare for evolving regulation. With the Cyber Security Strategy 2023–2030 setting new expectations, healthcare providers will be required to demonstrate higher levels of digital resilience and response readiness.
Building internal awareness and resilience
As we have all been taught by now, cybersecurity is not just about tools. It’s about culture. Managed services with managed security capability can support healthcare leaders in:
- Conducting security awareness training for staff
- Running phishing simulations
- Improving password hygiene
- Implementing MFA across systems
When combined with robust infrastructure and security protocols, this improves your ability to detect, respond, and recover.
