KDM Signs (“KDM”), a Cincinnati, Ohio-based company, recently reported a data security incident involving unauthorized access to its computer systems. According to information provided by the company, KDM experienced a network disruption on March 12, 2026, prompting an immediate response and investigation.
Upon discovering the disruption, KDM secured its network and engaged cybersecurity experts to determine the nature and scope of the incident. The investigation revealed that an unknown actor had entered the company’s systems and acquired certain data on or about March 11, 2026. Following this determination, KDM launched a comprehensive review of the affected information to identify potentially impacted individuals and assess what data may have been exposed.
The company stated that it moved as quickly as possible to review the affected records and provide notice to impacted individuals. According to the regulatory filing, the incident affected approximately one New Hampshire resident.
