Large-scale cyberattack hits half of Australia, surpassing previous attacks on Optus and Medibank.
The recent cyberattack on MediSecure has caused quite a stir, as half of Australia's population has been affected. However, despite the severity of the situation, the company is facing financial constraints that prevent them from identifying and notifying the individuals whose data has been stolen.

In an update released by the company's administrators, it was revealed that a staggering 12.9 million Australians had their details compromised in the hack that took place in April. This makes it even larger than the data breaches experienced by Optus and Medibank in 2022.

However, due to limited resources, MediSecure is unable to determine which specific customers have been impacted by the breach. The administrators explained that the data set was extremely complex and consisted of both structured and unstructured information, making it a daunting task to identify the affected individuals.

Despite their best efforts, the external advisor who analyzed the impacted server was unable to pinpoint the exact individuals and their information that had been accessed by the malicious third-party. The sheer volume of 6.5 terabytes of data that was stolen further complicated the matter, as it would have been a costly endeavor for MediSecure to identify and notify each affected person.

It is worth noting that the company has been under fire for its delayed response in notifying the public of the incident, which took place in April but was only made public in May. This has raised concerns about the company's transparency and accountability.

In addition to this, MediSecure's subsidiary Operations MDS has also gone into liquidation, as it was found to be the main trading entity of the corporate group. This has further complicated the situation, as the company has not been able to provide its services since November 15 due to the federal Health Department's decision to make eRx the sole e-script provider.

All in all, the cyberattack on MediSecure has caused major disruptions and raised serious concerns about the security of personal information in Australia. It is a wake-up call for companies to prioritize cybersecurity and ensure the protection of their customers' data.
