National Directorate of Health Surveillance

The National Directorate of Health Surveillance, known also by its acronym DINAVISA, is a governmental entity based in Paraguay. Its official title indicates that it operates as a national directorate within the country's public administration. The organisation's name reflects a focus on monitoring and assessing public health conditions. As a directorate, it likely functions under a broader ministry or secretariat of the Paraguayan state. Its headquarters are situated in Paraguay, placing it within the national administrative framework. The entity's role is tied to health surveillance activities, which involve the collection and analysis of health‑related data.

On June 1, 2025, DINAVISA was among several Paraguayan government portals that experienced unauthorized access detected by the Ministry of Information and Communication Technologies. The breach was traced to the use of leaked user credentials that had been harvested by infostealer malware designed to exfiltrate sensitive information. In response, the affected organisations activated their incident response protocols with the assistance of their information security officers and the national cyber incident response team. Investigations confirmed that the compromises stemmed from the compromised credentials rather than from vulnerabilities in the web applications themselves. The ministry reported that the incidents were contained after the response actions were taken. No further details about the scope of data exposure or potential impact on health‑surveillance operations were disclosed in the available sources.
