Stockton Cardiology’s Data Breach Investigation
Stockton Cardiology, a healthcare provider with offices in Lodi, Stockton, Manteca, Tracy, and San Andreas, California, reported a data breach involving unauthorized access to patient and business information. The breach was first identified on December 15, 2025, when suspicious emails were sent to several employees. Although the emails were deleted as part of initial security measures, a subsequent investigation revealed that files containing sensitive information had been accessed and removed from Stockton Cardiology’s systems on January 17, 2026.
The company continued to investigate the breach, and on February 17, 2026, it was determined that some of the compromised files had been publicly disclosed following the unauthorized access. The affected files potentially included personally identifiable information (PII), protected health information (PHI), and company business records.
Although Stockton Cardiology’s systems and operations were not entirely compromised, the exposure of sensitive patient and business data still presents a significant risk. The types of data involved in this breach can be used for identity theft, medical fraud, or phishing attacks.
To mitigate the potential harm caused by this breach, Stockton Cardiology is offering affected individuals complimentary credit monitoring services for one year through its partner vendor, Epiq.
