Hacker selling 7 TB of Star Health Insurance’s customer data using Telegram

In response, Star Health confirmed the breach, stating that it has reported the incident to local authorities, including the Tamil Nadu cybercrime department and the national cybersecurity agency CERT-In.

The company, which has a market capitalization exceeding $4 billion, claimed in a statement to the news agency that its initial investigation found “no widespread compromise” of customer data and that “sensitive data remains secure.” However, media investigations have uncovered detailed personal information being shared, contradicting the company’s initial assessment.

As of now, Star Health has not provided an updated estimate of the extent of the breach or notified affected customers directly. Customers who have had their medical records and ID documents leaked, including individuals such as policyholder Sandeep TS, confirmed the authenticity of the exposed data but were not informed of the breach by the company.
