Yap's Health System Targeted in Ransomware Attack
Yap, a state in the Federated States of Micronesia (FSM), recently faced a significant cybersecurity incident when its government health agency was hit by a ransomware attack. The attack, detected on March 11, 2025, forced the shutdown of all computers in the health department to contain the threat.
Yap, known for its traditional culture and stone money (rai stones), is part of the FSM, a Pacific island nation. Consisting of four main islands and several atolls, Yap's economy relies on subsistence farming, fishing, and tourism. The state has a population of around 11,000 people.
Officials from Yap's Health Department announced the attack on Facebook, reassuring the public that services would continue, albeit at a slower pace. The announcement stated:
“On March 11, 2025, at 3:00 PM, Yap Department of Health Services IT unit detected a cyberattack ransomware on the network. In response, the whole network was taken offline. As a result, the Department now doesn’t have internet connectivity, and all computers are returned off to prevent further damage. DHS is working with the FSM Department of Health and Social Affairs and private IT contractors to assess the extent of the infiltration, determine what data has been breached, and to get services back online as soon as possible at the moment. Email communication through the health servers and all digital health systems are shut down.”
The Health Department is working with other government agencies and external IT contractors to investigate the incident and restore the affected systems and services. No ransomware group has claimed responsibility for the attack.
This incident is not the first of its kind in the Pacific region. Previously, countries like Tonga, Vanuatu, and the Philippines have also been targeted by ransomware attacks.
Conclusion
The ransomware attack on Yap’s health system underscores the urgent need for enhanced cybersecurity measures in healthcare and government sectors. As cyber threats continue to evolve, proactive strategies and robust defenses are essential to safeguard critical infrastructure and ensure the continuity of essential services.
