Renkim Corporation Falls Victim to March 2025 Cyberattack
Renkim Corporation, a Southgate, MI-based provider of print, mail, text, and electronic mail solutions, has announced a data breach involving the protected health information of 46,592 individuals. Suspicious activity was identified within its computer network on March 3, 2025. Assisted by third-party cybersecurity experts, Renkim confirmed unauthorized access to its network between March 2 and March 3, 2025, and said files were likely exfiltrated in the incident.
The files have now been reviewed and found to contain information provided by its clients to allow mailings to be sent, which typically includes full names, contact information, client name, client account number, and dates of service. In limited cases, the compromised information included Social Security numbers and dates of birth. Notification letters are now being mailed to the affected individuals. Ballard Health and NYC Health + Hospitals (5,728 individuals) are among the affected clients.

The investigation confirmed that names, addresses, medical treatment information, and health insurance information were exposed in the incident and potentially stolen. Notification letters are now being mailed to the affected individuals, and steps have been taken to improve security to prevent similar incidents in the future. Southern Connecticut Vascular Center said it was unaware of any misuse of the affected data at the time of issuing notifications.
The nature of the cybersecurity incident was not explained in the letters; however, this appears to have been a ransomware attack by the Inc. Ransom group, which has added The Vascular Experts to its dark web data leak site. Screenshots have been added to the listing as proof of data theft, with further data releases promised in the next two days. The data breach is not currently listed on the HHS’ Office for Civil Rights data breach portal, so it is currently unclear how many individuals have been affected.
