A Ransomware Attack Brings Down Health System in Yap, Micronesia

The tiny Pacific island nation of Yap, one of the four states that make up the Federated States of Micronesia (FSM), has been hit by a devastating ransomware attack. The attack, which occurred on March 11, 2025, forced the shutdown of all computers in the state's government health agency, leaving thousands of residents without access to medical services.

Yap is a remote island nation with a population of around 11,000 people, whose economy relies heavily on subsistence farming, fishing, and some tourism. The state is known for its rich cultural heritage, including traditional stone money (rai stones) and stunning diving spots that attract visitors from around the world.

The ransomware attack was detected by the Yap Department of Health Services IT unit at 3:00 PM on March 11, 2025. In response, the entire network was taken offline to prevent further damage. As a result, the department lost internet connectivity and all computers were shut down to protect sensitive information.

According to officials, the attack is being investigated by the Yap Health Department in collaboration with other government agencies and external IT contractors. The department has reassured the public that services are continuing, albeit at a slower pace due to the disruptions.

"On March 11, 2025, at 3:00 PM, our IT unit detected a cyberattack ransomware on the network," said an official announcement on Facebook. "In response, we took the whole network offline to contain the threat. As a result, we don't have internet connectivity, and all computers are returned off-line to prevent further damage."

The department has assured that email communication through health servers and digital health systems is currently shut down. Despite the challenges posed by the attack, officials are working tirelessly to resume impacted systems and services as soon as possible.

This incident marks the latest in a string of ransomware attacks that have hit Pacific island nations in recent years. Tonga, Vanuatu, and the Philippines were all affected by similar attacks in the past.

The Yap Health Department has issued a statement urging patience and understanding from the public as services continue to be disrupted. The department will provide regular updates on the situation as it develops.
