Aurora, Colo., Nov. 13, 2026 (GLOBE NEWSWIRE) — UCHealth is notifying individuals of a recent data security incident in which accounts were inappropriately accessed.
On July 27, 2026, UCHealth discovered that an unauthorized third party gained access to two employee accounts in UCHealth’s Microsoft cloud system. As soon as this was discovered, UCHealth launched an internal investigation, secured the affected accounts and cloud environment from further unauthorized access, and notified law enforcement. UCHealth’s investigation determined that the activity was limited to certain services within the cloud system and that the unauthorized third party may have acquired certain files stored there. Importantly, UCHealth’s electronic health record was not accessed.
UCHealth’s investigation of the accessed files found that some contain personal information related to certain individuals. Depending on the individual, the information may include their name, Social Security number, driver’s license number, health information, and billing information. UCHealth’s security team and outside experts have monitored for any subsequent leak or use of this data and have not found any evidence that it was inappropriately used or further disclosed. UCHealth is mailing notification letters to about 129,000 individuals whose information was potentially involved and for whom it has a valid address. UCHealth’s review remains ongoing in accordance with state and federal requirements.
Involved individuals should refer to the notice they receive from UCHealth for steps they can take to protect themselves. UCHealth has arranged for individuals whose Social Security numbers or driver’s license numbers were involved in the incident to enroll in a complimentary one-year membership in Medical Shield Total. As a precautionary measure, individuals should remain vigilant about potential fraud and/or identity theft by reviewing account statements and monitoring credit reports closely. If individuals detect suspicious activity on an account, they should promptly notify the financial institution or company that maintains the account. They should also report fraudulent activity or suspected identity theft to law enforcement, including the police and their state attorney general.
