In a shocking revelation, MediSecure, an eprescription provider, has confirmed that approximately 12.9 million Australians have been affected by a cyberattack that occurred in April. This incident has surpassed previous notable breaches, including the Optus and Medibank data breaches in 2022, in terms of the number of individuals impacted.
The administrators of MediSecure, FTI Consulting, disclosed that the compromised data includes individuals' healthcare identifiers. However, due to the complexity and sheer volume of the data involved, identifying the specific individuals whose data was stolen is financially unfeasible for the company. This inability to pinpoint affected individuals prevents MediSecure from notifying them about the breach.
Data Complexity and Financial Constraints
The compromised server contained 6.5 terabytes of data, equivalent to billions of pages of text. This data was stored in a mix of semi-structured and unstructured formats, making it extremely difficult to analyse without incurring substantial costs. The encrypted nature of the server further complicates efforts to determine the exact information accessed by the malicious actors. MediSecure's financial limitations have left the company unable to afford the extensive resources needed to sift through the massive amount of data.
Notification Delays and Administrative Actions
Despite the hack occurring in April, MediSecure did not make the incident public until May. The delayed notification has raised concerns about the company's crisis management and communication strategies. Subsequently, the company entered administration in June, and its subsidiary, Operations MDS, went into liquidation. This subsidiary was identified as the main trading entity of the corporate group, highlighting the severe impact of the cyberattack on the company's operational capabilities.
Impact on Healthcare Services
MediSecure had provided a crucial service that allowed healthcare professionals, such as general practitioners, to send electronic prescriptions to patients. However, this service has not been used for new electronic prescriptions since November 15, following a decision by the federal Health Department to designate eRx as the sole e-script provider. This shift has left many healthcare providers scrambling to adapt to the new system, further complicating the ecosystem for electronic healthcare services in Australia.
The MediSecure cyberattack highlights the growing threat of data breaches and the challenges companies face in managing and mitigating such incidents. With 12.9 million Australians potentially affected and the company unable to notify them, the breach underscores the need for robust cybersecurity measures and the financial resilience to respond effectively to such crises. This incident serves as a stark reminder of the vulnerabilities that exist in the digital age and the critical importance of safeguarding sensitive information.
In the aftermath of several high-profile cyber attacks targeting key entities like Optus and Medibank, Australia is doubling down on its efforts to bolster cybersecurity across the nation. The Australian government has unveiled a comprehensive plan to overhaul cybersecurity laws and regulations, aiming to strengthen the country's resilience against evolving cyber threats.
A recent consultation paper released by government officials outlines a series of proposed reforms designed to position Australia as a global leader in cybersecurity by 2030. These proposals include amendments to existing cybercrime laws and revisions to the Security of Critical Infrastructure (SOCI) Act 2018, with a focus on enhancing threat prevention, information sharing, and cyber incident response capabilities.
The vulnerabilities exposed during the cyberattacks, attributed to basic errors and inadequate cyber hygiene, have highlighted the urgent need for improved cybersecurity practices. As part of the government's strategy, collaboration with the private sector is emphasised to foster a new era of public-private partnership in enhancing Australia's cybersecurity and resilience.
Key reforms proposed in the consultation paper include mandating secure-by-design standards for Internet of Things (IoT) devices, instituting a ransomware reporting requirement, and establishing a national Cyber Incident Review Board. Additionally, revisions to the SOCI Act 2018 aim to provide clearer guidance for critical industries and streamline information-sharing mechanisms to facilitate more effective responses to cyber threats.
Australia's expansive geography presents unique challenges in safeguarding critical infrastructure, particularly in industries such as mining and maritime, which rely on dispersed and remote facilities. The transition to digital technologies has exposed legacy equipment to cyber threats, necessitating measures to mitigate risks effectively.
Addressing the cybersecurity skills gap is also a priority, with the government planning to adopt international standards and provide prescriptive guidance to enforce change through mandates. However, some experts have pointed out the absence of controls around software supply chains as a notable gap in the proposed policy.
Recognising our responsibility in enhancing cybersecurity, both the government and the private sector are making significant investments in information security and risk management. Gartner forecasts a substantial increase in spending on cloud security and other protective measures driven by heightened awareness and regulatory requirements.
With concerted efforts from stakeholders and a commitment to implementing robust cybersecurity measures, Australia aims to strengthen its resilience against cyber threats and secure its digital future.
The Department of Defence is afraid that the personal information of personnel, like DoB, may have been breached after a communications platform used by the military suffered a ransomware attack.
Hackers attacked the ForceNet service, which is operated by an external information and communications technology (ICT) provider.
The organisation in the beginning told the Defense Department no data of former or current personnel was breached.
However, the Department of Defense believes that personal details like the date of enlisting and DoB may have been stolen, despite initial hints being contrary to what the external provider is saying.
In a message notification to the staff, the defence chief and secretary said the issue is being taken "very seriously."
There has been a series of cyberattacks in recent times, from health insurance companies to telecommunications.
Medibank earlier this week confirmed a criminal organization behind a cyber attack on its company had access to the data of around 4 million customers, some of these consist of health claims.
In September, Optus said a cyberattack had leaked the data of around 10 Million Australian users, with a considerable amount of information stolen from around 2.8 million people.
Minister for Defense Personnel Matt Keogh ForceNet kept upto 40,000 records, saying "I think all Australians, and rightly the Australian government, is quite concerned about this sort of cyber activity that's occurring, people seeking through nefarious means to get access to others' personal data."
In the email to the staff, the Defense Department was confident that the hack of ForceNet was not targeted at the IT systems of the department.
It said "we are taking this matter very seriously and working with the provider to determine the extent of the attack and if the data of current and former APS [Australian public service] staff and ADF personnel has been impacted. If you had a ForceNet account in 2018, we urge you to be vigilant but not alarmed."
Earlier talks with the service provider hint that there is no substantial proof that data of former and current ADF Personnel and APS staff personnel have been breached.
It said, "we are nevertheless examining the contents of the 2018 ForceNet dataset and what personal information it contains."
