Cardiovascular Institute of New England (“CINE”), a cardiology practice headquartered in Providence, Rhode Island, has issued a notice of data security incident that may have compromised sensitive personal and health information belonging to patients and employees. Healthcare providers hold some of the most sensitive personal data that exists, and patients place significant trust in these practices to keep that information secure.
Cardiovascular Institute of New England’s Data Breach Investigation
According to a media notice released on July 31, 2026, CINE observed unusual activity in its email environment in February 2026. An investigation into the incident revealed that some personal information may have been subject to unauthorized access. CINE states it does not have any reason to believe that there has been any identity theft, fraud, or misuse of information in connection with this incident, though the practice has begun notifying affected individuals as a precaution.
Healthcare organizations remain one of the most frequently targeted sectors for data breaches, largely because medical records combine highly sensitive personal, financial, and clinical information in a single record, making them especially valuable on the black market. Email-based intrusions, like the one CINE describes, are among the most common entry points cybercriminals use to gain access to a healthcare provider’s systems, often through phishing attacks or compromised employee credentials.
The exposure of medical diagnosis, treatment, and prescription information alongside financial account numbers and Social Security-adjacent identifiers like dates of birth creates a particularly serious risk profile. This combination of data can be used not only for conventional identity theft and financial fraud, but also for medical identity theft, in which a criminal uses a victim’s information to fraudulently obtain medical services or prescription medications, potentially corrupting the victim’s own medical records in the process.
CINE has not publicly disclosed the specific number of individuals affected by this incident, nor has it identified a specific cause such as ransomware or a particular threat actor. The practice’s own public notice remains the primary source of information about the incident as of this writing.
When Did This Breach Occur?
CINE first observed unusual activity in its email environment in February 2026, with the specific date identified as February 12, 2026. The practice began notifying affected individuals on July 30-31, 2026, several months after the incident was first detected, which is not unusual given the time typically required to complete a forensic investigation into the scope of a breach before notification.
What Information Was Breached?
According to CINE’s public notice, the information that may have been involved in this incident includes names, phone numbers, dates of birth, financial account numbers, medical information, medical diagnosis and treatment information, treatment locations, clinical information, prescription information, and medical insurance provider information. CINE has not publicly disclosed the total number of individuals affected.
