Jackson County, Missouri, confirms ransomware attack after declaring a state of emergency on Tuesday.

The FBI, federal Department of Homeland Security, Missouri Highway Patrol, and the county sheriff’s office are part of the ongoing investigation.

We are currently in the early stages of our diagnostic procedures, working closely with our cybersecurity partners to thoroughly explore all possibilities and identify the root cause of the situation. While the investigation considers ransomware as a potential cause, comprehensive analyses are underway to confirm the exact nature of the disruption.

The ransomware attack’s impact on April 2 elections

The authorities say the ransomware attack impacted several systems, including tax payments and online property, marriage license, and inmate searches. They also announced closing the Assessment, Collection, and Recorder of Deeds offices indefinitely.

The attack happened on April 2nd, the same day as the special election. However, the system outage didn’t affect the Kansas City Board of Elections and Jackson County Board of Elections.

Until now, researchers haven’t found any evidence of hackers succeeding in compromising any data, but the investigation is still at the beginning.

Local citizens expressed disbelief and concern regarding the integrity of their data. Comments on social media show a lack of trust in the authorities’ capability to protect their sensitive information.

Hackers recently targeted other public services in Missouri with ransomware.

Liberty Hospital suffered a ransomware attack in December 2023 and had to transfer patients to other hospitals. Then the Kansas City Area Transportation Authority (KCATA) was hit in January.

In February this year FBI’s cybersecurity specialists warned the nation’s state election administrators hackers will be increasingly active due to presidential elections in November.
