Oracle Health data breach exposes nearly 20 million patients

When you visit a doctor or hospital, you expect your medical information to stay private.

After all, your health records can reveal some of the most personal details about your life.

Now, a massive cyberattack involving Oracle Health is raising serious questions about how well that information is protected.

Nearly 20 million people reportedly had their personal and medical information compromised in a cyberattack involving older Cerner systems.

The attack dates back to early 2025, but new details about its reach are still emerging.

For patients, the concern goes well beyond stolen passwords.

Hackers may have obtained Social Security numbers, diagnoses and even medical images.

MEDICAL IDENTITY THEFT FOLLOWS YOU INTO THE DOCTOR'S OFFICE The Oracle Health data breach appears to be much larger than earlier patient notifications suggested.

According to figures reported in filings with the Texas Attorney General, the personal and medical information of approximately 19.9 million people was compromised in a cyberattack involving legacy Cerner systems.
