What Happened?
On January 17, 2026, we discovered that certain files maintained in the ordinary course of business and patient care may have been accessed and removed from our systems by the unauthorized individual. Immediately thereafter, we started our investigation to determine the scope of the breach and to restore the integrity of our system. On February 17, 2026, we learned that some of these files have since been publicly disclosed.
What information was involved?
The information potentially involved in this incident may have included patient names, mailing addresses, email addresses, and billing records that may contain limited medical information associated with services provided.
What is Stockton Cardiology Medical Group doing to help?
Following the breach, Stockton Cardiology has taken several steps to investigate the incident and strengthen its security measures, including retaining an independent security firm, improving the security configuration of its information systems, shutting down an older remote access service used by staff, implementing multi-factor authentication on certain internal systems, resetting all system passwords, and reviewing data retention policies to reduce the number of active “working” files maintained. Stockton Cardiology Medical Group is also helping affected individuals by offering one year of complimentary credit monitoring services through its partner vendor, Epiq, to monitor potential misuse of personal information.
