iRhythm Technologies Inc. reported a data breach to the Texas Attorney General in 2026, confirming exposure of sensitive personal and health information. This incident impacts individuals whose Full Name, Date of Birth, Social Security Number, and medical data were compromised.

iRhythm Technologies Inc. filed a data breach report with the Texas Attorney General on October 6, 2026, concerning an incident discovered around June 3, 2026. The company, which specializes in cardiac monitoring solutions, confirmed that a cybersecurity event led to the exposure of sensitive personal information. Details about the specific nature of the breach remain under investigation.

The information reported exposed in this breach includes Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Cardiac Monitoring and ECG Data, and Provider and Treatment Dates. The exposure of these data types, particularly health-related and identifying information, can pose significant risks to affected individuals.

This combination of sensitive personal identifiers and detailed health records means that compromised individuals could face an elevated risk of medical identity theft or other forms of fraud. Unlike financial data, which can often be canceled, this type of health and identity information can be exploited for a longer period.

Individuals who receive a breach notification from iRhythm Technologies Inc. should review it carefully for specific guidance. It is generally recommended to monitor credit reports and statements from healthcare providers for any unusual activity. Consider placing a fraud alert or credit freeze with credit bureaus. If medical identity theft is suspected, report it to relevant authorities and your health insurer. This information is based on public breach filings.

Commonly recommended next steps

Freeze your credit
Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.
Watch your financial accounts
Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.
Check for medical identity theft
Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.
Stay alert to targeted scams
Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.
Keep your notification letter
Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
