What was the nature of this security breach?
West Publishing Corporation, the vendor of the software that has provided case management systems for the Wyoming Judicial Branch, experienced a data security breach involving court information from court systems. Wyoming Judicial Branch computer systems were not part of the attack and were not affected.

What information was involved?
Information on the Wyoming Supreme Court and district courts was affected. At this point, we understand that personal information, including names, addresses, and dates of birth, was compromised, but the Wyoming Judicial Branch continues to work with law enforcement and the vendor to determine next steps.

How and when did this happen?
The breach occurred in the spring of 2026. The Wyoming Judicial Branch learned of the breach in late July and, upon reviewing the impacted data, determined that limited personal information was involved in the breach in August 2026. Bad actors accessed West Publishing Corporation’s systems through a vulnerability in its infrastructure.

How many people does this impact?
We are still working through the information to determine how many people were affected and what information was compromised. However, we believe that the individuals primarily affected are those who came into contact with the district courts or Supreme Court between 2015 and 2025. If you fall into this category, we encourage you to utilize the resources offered by West Publishing Corp.

Why does an external vendor (West Publishing Corporation) have state court data in the first place?
West Publishing Corporation is the vendor that has provided software that allows the Supreme Court and the district courts to operate effectively. We share data with West Publishing Corporation so the company can provide technical support for its systems, ensuring their continued operation.

Since West Publishing Corporation manages these systems for many courts, do you know whether other courts in the country were similarly affected?
We are aware of several other state court systems that have been impacted.

What is the Wyoming Judicial Branch doing to secure and protect the data of Wyoming court users in the wake of this attack?
Even though Wyoming Judicial Branch software and computer systems were not impacted, the Judicial Branch continues to actively monitor and block threats from bad actors. Court users should feel confident that their information remains safe.

How will I know if my information has been compromised?
It is too early in the process to determine whose information has been compromised. When those details emerge, we will take appropriate action and provide further public and direct communication as needed. However, we believe that the individuals primarily affected are those who came into contact with the district courts or Supreme Court between 2015 and 2025. If you fall into this category, we encourage you to utilize the resources offered by West Publishing Corp.

If I could have been affected, what do I need to do?
If you believe you may have been affected, West Publishing Corporation has offered free credit and identity monitoring services for 12 months. Regardless of whether you choose to enroll or not, you should always be vigilant about your personal information. To enroll, call 1-833-918-5294 toll-free Monday through Friday from 8 am to 8 pm Central Time (excluding major U.S. holidays). If you have a speech or hearing impairment and use a TTY, please call 711. Be prepared to provide engagement number B171847.
