MediSecure hit by ‘large-scale ransomware data breach’

2 minute read


Federal investigators are on the case, while MediSecure reveals a possible source of the cyberattack.


Electronic prescriptions provider MediSecure is the private health group hit in what the feds have described as a “large-scale ransomware data breach”.

MediSecure’s software lets people get their scripts from their doctor digitally. That suggests personal medication information may have been leaked online.

MediSecure’s website is out of action, other than a statement posted on its homepage. The company said it had “taken steps” to limit the damage of the hack and was working with authorities.

“While we continue to gather more information, early indicators suggest the incident originated from one of our third-party vendors,” the statement reads.

“MediSecure takes its legal and ethical obligations seriously and appreciate this information will be of concern.”


In a statement National Cyber Security Coordinator, Lieutenant General Michelle McGuinness CSC confirmed the attack. 

Lt-Gen McGuiness said the Australian Signals Directorate’s Australian Cyber Security Centre was aware of the incident and the Australian Federal Police was investigating. 

Federal Home Affairs Minister Clare O’Neil took to social media to reveal she had been briefed on the incident and that the government had “convened a National Coordination Mechanism regarding this matter today”.
