Australia’s largest not-for-profit health and aged care network has confirmed that it was unlikely hackers had stolen patients’ sensitive information following a data breach in December 2023.
On Jan. 25, St Vincent’s Health Australia announced the result of a month-long forensic investigation into the hack.
Experts from the cyber security firm CyberCX found there was no evidence that cybercriminals were able to retrieve sensitive personal information from the hospital network’s database.
“Monitoring activities have not detected evidence of any stolen data being posted on the dark web.”
After the incident occurred, the hospital network quickly took measures to isolate the data breach and inform relevant government departments.
As the investigation progressed, CyberCX experts found 4.3 gigabytes worth of system, configuration data and network credential data were stolen from St Vincent’s database prior to Dec. 19.
“As part of our immediate response, we have been undertaking necessary system remediation activities [and] this includes enhancing our 24-hour, seven-day-a-week monitoring across our digital environment to detect and respond to suspicious activity,” the hospital network said.
St Vincent’s CEO Chris Blake also stated that he had informed Cyber Security Minister Clare O'Neil about the investigation’s findings and expressed gratitude to federal and state governments for their support.
“Our partners in the NSW, Victorian, and Queensland departments of health have worked closely with us to ensure the on-going safe delivery of our mission to our patients and residents around Australia.”
St Vincent’s data breach is the latest incident in a series of cyberattacks targeting large corporations and government agencies since September 2022 that rocked the country.
Australia Imposes Sanctions on Russian Hacker
St Vincent’s announcement comes just days after the Australian government imposed cyber sanctions on a Russian individual for hacking the database of Medibank, one of Australia’s largest health insurers, 18 months ago.The Australian government found Russian citizen Aleksandr Ermakov responsible for the cyberattack, which resulted in 9.7 million records being allegedly stolen, including Medicare numbers, sensitive medical information, dates of birth, and names.
The attack also caused Medibank to suffer $46.4 million (US$30.5 million) in financial damage.
As a result, the federal government imposed a travel ban and targeted financial sanctions on the Russian man, making it a criminal offence to provide assets or financial services to him.
Foreign Minister Penny Wong said the cyber sanctions would send a clear message to cybercriminals that there would be “costs and consequences” for targeting Australia and its citizens.
However, Shadow Home Affairs Minister James Paterson questioned why the federal Labor government took so long to take action.
“While the announcement this morning of Magnitsky sanctions against Russian cyber criminals is welcome, the question is what took the Albanese government so long? The Opposition first called on them to do so in November 2022,” he said on X.
