Seattle, WA – Kosmos Management LLC (“Kosmos”) has become aware of a data security incident that may have impacted personal information belonging to certain individuals. Kosmos is not aware of any evidence to suggest that any information has been misused. 

On or around February 4, 2025, Kosmos discovered suspicious activity potentially related to an employee email account. Upon discovery, Kosmos immediately took steps to secure its email tenant and engaged third-party computer specialists to investigate the full nature and scope of the incident. Through the investigation, it was determined that a limited amount of data in two Kosmos email accounts may have been subject to unauthorized access. Kosmos then immediately began a thorough review of the potentially impacted data to identify what type of information was contained therein, and to whom that information belonged.

This review was recently completed on November 6, 2025. Following the comprehensive and time-intensive analysis, Kosmos determined that information contained in the affected email accounts may have included personally identifiable information (“PII”). The type of information contained within the affected data set may include a first and last name, in combination with one or more of the following: Social Security number, driver’s license or state identification number, medical diagnosis or treatment information, and/or health insurance information.

At this time, Kosmos is not aware of any evidence to suggest that any information has been fraudulently misused. However, in an abundance of caution, Kosmos is notifying potentially impacted individuals of this incident. Although Kosmos has no reason to believe any individual’s information has been or will be misused as a result of this incident, individuals are nonetheless encouraged to monitor their account statements for suspicious activity and to detect errors.
