Anthem, Inc. Data Breach Exposes SSNs & Medical Info

On Nov. 19, 2025, health insurance giant Anthem, Inc. disclosed a significant data breach. According to the disclosure, the cybersecurity event may have exposed personally identifiable information (PII) as well as protected health information (PHI) of at least 1,162 individuals in Massachusetts alone.

The exact details of the breach are not yet known, and the investigation is ongoing, but according to the Massachusetts Attorney General's office, it may have exposed a range of sensitive data, including names, addresses, dates of birth, Social Security numbers, medical records and driver’s license numbers.

This incident is particularly severe, as it involved both personally identifiable information (PII) and protected health information (PHI) of affected individuals.

The breach’s impact is notable due to the volume and sensitivity of the data involved. Social Security numbers and driver’s licenses are key targets for identity thieves, while medical records can be used for fraud or blackmail. The exposure of both PII and PHI increases the risk profile for those affected, as it can lead to a range of financial and personal harms.
