In 2023, **23andMe** suffered a major data breach exposing highly sensitive genetic and ancestry data of nearly **7 million users**. The compromised information included **chromosomal haplogroups, family tree details, and ancestry profiles**, with ethically charged consequences—such as curated dark web lists targeting individuals of **Jewish and Chinese descent**. Initially, the company **blamed users for weak passwords**, exacerbating public distrust. The fallout led to a **costly class-action lawsuit**, severe reputational damage, and heightened scrutiny over the company’s data stewardship practices. The breach underscored the risks of mishandling **biometric and genetic data**, which, unlike financial records, **cannot be changed if exposed**. The incident also highlighted systemic failures in **incident response, transparency, and ethical data management**, reinforcing the need for stricter protections around **health-related and personally identifiable information (PII)**.
