The Widespread Impact of the 23andMe Data Breach on National Security

The recent data breach at 23andMe, which compromised over 14,000 customer accounts, not only underscores a significant vulnerability in the domain of genetic background and family tree services but also highlights the potential global ramifications and specific implications for Australian national security.

In its official filing, 23andMe revealed that the initial breach affected approximately 14,000 users, with the compromised data primarily including ancestry details. For some of these accounts, health-related information derived from users' genetics was also accessed. Additionally, the hackers obtained various profile information and subsequently published unspecified details online.

The breach extended beyond the directly affected accounts due to 23andMe's DNA Relatives feature. This function, when opted into by users, enables the sharing of certain personal information with connected individuals.

Consequently, the breach of a single account inadvertently exposed the personal data of related users, amplifying the impact of the hack.

Separately, earlier this year, a more extensive potential breach was reported, initially brought to light by TechCrunch in October. An investigation uncovered a claim by another hacker on a different forum, boasting about possessing 300 terabytes of stolen 23andMe data.

This individual sought $50 million for the entire database, offering subsets of the data for prices ranging from $1,000 to $10,000.

This claim suggests a far broader scope of data vulnerability than initially understood, raising further concerns about the security of personal and genetic information held by 23andMe.

In October, reports emerged about a significant data breach involving the unauthorised access and advertisement of sensitive user data on a prominent hacking forum.

Initially, the breach was revealed when hackers publicly offered the data of one million users of Jewish Ashkenazi descent and 100,000 Chinese users.

Approximately two weeks following this disclosure, the same hacker escalated the situation by advertising the records of an additional four million individuals. The data of these victims was being marketed for sale, with prices ranging from $1 to $10 per individual's information.

Lessons from the 23andMe Incident and Australian Cyber Strategy

The recent 23andMe data breach, exposing sensitive genetic data, underscores a critical issue at the intersection of privacy, national security, and cyber policy.

This event poses significant questions for the future of national cyber strategies, particularly in the context of the Australian National Cyber Strategy 2030 and its emphasis on the 'Cyber 6 Shields Plan'. The focus is on enhancing protection for citizen data and neutralising potential harm.

Genetic data, with its unique capacity to reveal deep personal insights, extends the impact of breaches beyond conventional privacy concerns to global security risks.

This situation is particularly pertinent in a digitally connected world where a breach's impact is not confined to one region. In Australia, where stringent data privacy and security measures are in high regard, such incidents not only trigger alarm about citizen data safety but also raise broader questions about the adequacy of current regulatory frameworks.

The profound global impact of genetic data breaches, with potential for identity manipulation and medical record tampering, is akin to a critical infrastructure hack.

The 23andMe incident, though limited in scale, highlights the vulnerability of digital repositories of sensitive information and the potential for a systemic trust breakdown in digital services.

For Australian national security, the implications are even more grave. Such breaches could expose vulnerabilities in population health profiles, opening doors to biosecurity threats of bioterrorism.

Additionally, the theft of genetic data could be exploited for espionage, targeting individuals in power or with access to sensitive information.

Given these risks, there is a pressing need for Australian service providers and policymakers to prioritise cybersecurity in the genetic data sector.

This involves implementing stringent data protection measures, conducting regular security audits, and promoting a culture of cybersecurity awareness among users. 

Moreover, this situation calls for a reassessment of the regulatory landscape. Questions arise about whether existing laws, such as those under the Security of Critical Infrastructure Act 2018 (SOCI Act), which mandates risk management programs and cyber incident reporting for critical health institutions, are sufficient for providers handling genetic information.

There is a compelling argument for introducing stricter regulatory oversight and enhanced policing for such providers, akin to the requirements imposed on major healthcare institutions under the SOCI Act.

This might include mandatory reporting of incidents and stringent compliance with risk management protocols.

In conclusion, the 23andMe breach serves as a critical reminder of the vulnerabilities in handling sensitive genetic data and the need for robust, internationally coordinated cybersecurity strategies.

For Australia, this incident catalyses a reevaluation of its national cyber strategy, particularly concerning the protection of genetic data, to ensure individual privacy and safeguard national security.
