Profile
Keralty is a multinational healthcare organization headquartered in Colombia that delivers medical services and maintains digital platforms to support patient care across the countries where it operates. The organization’s network includes clinical facilities, appointment scheduling systems, and websites that enable the delivery of healthcare solutions to a diverse patient base. Its operations rely on integrated information technology infrastructure to coordinate services, manage patient records, and facilitate communication between providers and users.
On November 27 2022, Keralty suffered a ransomware attack carried out by the RansomHouse group, which encrypted files with the “.mario” extension and disrupted IT systems, websites, and medical services throughout its network. The disruption led to appointment scheduling breakdowns, forced a return to manual processing, and caused extended patient wait times that compromised the timeliness and quality of care. Attackers claimed to have exfiltrated approximately three terabytes of data, although this assertion has not been independently verified. The incident prompted the organization to activate contingency measures in an attempt to sustain critical functions while addressing the immediate impact of the malware.
In the aftermath, Keralty implemented recovery efforts aimed at restoring normal operations, yet reports indicated that service issues persisted and patient distress continued during the remediation phase. The organization’s response focused on rebuilding affected systems, reinforcing security controls, and managing the operational fallout from the attack. These efforts highlighted the challenges faced by healthcare providers in maintaining service continuity when confronted with sophisticated cyber threats that target both clinical and administrative technology layers. The episode underscored the importance of resilient cybersecurity strategies within multinational healthcare enterprises to protect patient information and ensure uninterrupted care delivery.
