South Africa’s National Health Laboratory Service (NHLS) is currently facing challenges in recovering from a ransomware attack that disrupted its systems and deleted backups. The attack, which occurred on June 22, targeted specific vulnerabilities in the NHLS’s information infrastructure, resulting in communication blockages between the laboratories’ information systems and other medical databases. This disruption led to delays in lab testing across public health facilities. Despite the setback, all laboratories are reported to be “currently fully functional and are receiving and processing clinical samples,” according to a statement published by the agency last week.

The timing of this ransomware attack couldn’t have been worse for South Africa, as the country is already grappling with stress on its healthcare systems due to an mpox outbreak that has resulted in 3 deaths and 16 laboratory-confirmed cases since May. Yotasha Thaver, a senior research analyst for IT security and software at IDC’s Middle East and Africa division, highlighted the additional strain the attack has put on the already overwhelmed public hospitals and clinics. The need to shut down systems to recover from the damages caused by the attack has further delayed the processing of lab tests in public health facilities, exacerbating the situation.

Ransomware attacks on the healthcare industry have been on the rise globally, with a significant increase in the number of organizations falling victim to such attacks. According to cybersecurity firm Group-IB, there was a 62% annual increase in successful ransomware attacks in Africa in 2023. Ivan Pisarev, head of threat intelligence for the Middle East and Africa at Group-IB, emphasized the widespread threat posed by ransomware, stating that it ranks among the top threats for all organizations and countries.

The impact of cyberattacks on healthcare organizations extends beyond operational disruptions and financial losses. A post-coronavirus pandemic analysis conducted by the US Cybersecurity and Infrastructure Security Agency (CISA) highlighted the long-term implications of such attacks on hospital capacity and patient care outcomes. The degradation of hospital capacity following a cyberattack can lead to worsened health outcomes, including excess deaths.

Given South Africa’s already burdened healthcare system, the effects of the ransomware attack are likely to be felt more acutely in the country. Thaver noted that delays in test results due to the attack could lead to further spread of infections, particularly in a developing country like South Africa with a high poverty rate and reliance on public health services.

To mitigate the risks posed by cyber threats, a multi-layered defense approach is recommended, including patching vulnerable systems, safeguarding credentials, and educating users about phishing attacks. Ignus De Villiers, managing executive for cybersecurity at Liquid C2, emphasized the importance of having effective incident response plans and seeking assistance from third-party experts in combating cyber threats.

In light of the growing prevalence of ransomware attacks, Thaver called for government intervention to support organizations in enhancing their cybersecurity posture. She suggested that the government should enforce strict compliance measures and provide clear guidelines for cybersecurity practices to ensure that all entities have basic security measures in place.

As South Africa continues to grapple with the aftermath of the NHLS ransomware attack, the need for proactive cybersecurity measures and government support becomes increasingly imperative to safeguard critical healthcare systems and protect patient care outcomes.
