Healthcare organisations in Australia are prime targets for cybercriminals, with phishing attacks ranking among the most common threats. These attacks compromise sensitive patient data, disrupt essential services, and put healthcare providers at risk of legal and reputational damage. Understanding the types of phishing attacks that threaten the healthcare sector is the first step in protecting your organisation and ensuring compliance with data protection regulations.
Email Phishing: A Common Threat to Healthcare
Email phishing is one of the most prevalent types of phishing attacks. Cybercriminals send fraudulent emails that mimic trusted sources, such as medical suppliers or internal departments. These emails often contain malicious links or attachments designed to steal login credentials or install malware.
Example: An email pretending to be from a medical supplier might request urgent payment updates, redirecting the recipient to a fake payment portal.
To combat email phishing, healthcare staff must be trained to identify warning signs like suspicious sender addresses, poor grammar, and unexpected requests for sensitive information.

Spear Phishing: Personalised Attacks on Healthcare Staff
Spear phishing targets specific individuals within a healthcare organisation. Attackers gather personal details to craft convincing messages that appear legitimate.
Example: A cybercriminal impersonating a department head might request confidential patient data from an employee, citing an “urgent deadline.”
Recognising these attacks requires heightened vigilance and protocols for verifying requests before acting.
Vishing: The Risks of Voice Phishing
Vishing, or voice phishing, involves phone calls from attackers impersonating trusted entities, such as insurance companies or hospital staff. These calls aim to extract sensitive information, such as billing details or patient records.
Example: A scammer posing as an insurance representative may pressure staff into sharing patient information under the guise of resolving a claim.
To prevent vishing, organisations should train employees to verify caller identities and avoid sharing sensitive information over the phone.
Recognising Phishing Attempts
Recognising types of phishing attacks is critical in preventing successful attacks. Employees should be trained to look for common signs of phishing, such as unexpected emails from unknown sources, requests for sensitive information or unusual sender addresses. Additionally, implementing multi-factor authentication can add an extra layer of security, making it more challenging for attackers to gain access even if credentials are compromised.
How to Identify Healthcare Phishing Attempts
Recognising phishing attempts is vital in preventing successful attacks. Healthcare organisations should train employees to watch for:
- Unexpected emails or calls from unknown sources.
- Requests for sensitive information, especially under time pressure.
- Suspicious links or attachments.
Implementing multi-factor authentication (MFA) adds an additional layer of security, making it harder for attackers to gain access even if credentials are compromised.
Protecting Patient Data from Phishing Attacks
To protect patient data, healthcare organisations must adopt a multi-layered approach:
- Staff Training: Conduct regular training sessions and phishing simulations to improve employee awareness.
- Security Software: Use updated antivirus, endpoint protection, and email filtering tools to detect and block phishing attempts.
- Data Encryption: Ensure sensitive patient data is encrypted to render it unusable if intercepted.
- Clear Protocols: Establish clear guidelines for handling suspicious communications and reporting incidents promptly.
By combining these measures, healthcare organisations can reduce the risk of data breaches and maintain compliance with data protection regulations.
Vigilance is Essential
Phishing attacks targeting healthcare organisations pose significant risks, but vigilance can mitigate their impact. Regularly updating software, conducting phishing simulations, and adopting advanced security solutions like multi-factor authentication are essential steps.
