California’s 23andMe Breach Lawsuit topic image

California Attorney General Rob Bonta sued 23andMe, also known as Chrome Holding Co.

in bankruptcy proceedings, over alleged failures connected to a 2023 breach affecting data associated with nearly seven million customers. The complaint alleges that attackers used credential stuffing and remained undetected for months, accessing sensitive genetic, health, ancestry, and family-related information. The case centers on California privacy and consumer-protection claims, including the defendant’s response to the breach and its bankruptcy-jurisdiction challenge. A proposed $6 million settlement is described as resolving California’s claims, including related concerns about genetic-data transfers during bankruptcy.

Bankruptcy-era data transfer and consent remain central

The bankruptcy sale transferred customers’ genetic information and samples, prompting California to argue that separate, explicit consent was required. Courts rejected the state’s objection, and the settlement resolves its appeal; customers retain options to request deletion, sample destruction, or withdrawal of research consent.

Previously

California Attorney General Rob Bonta has sued 23andMe, now identified in the case as Chrome Holding Co., over a 2023 breach that allegedly exposed genetic, health, ancestry, and relatives’ information tied to nearly 6.9 million U.S. customers. The complaint alleges credential-stuffing and other weaknesses enabled access for about five months, and that the company failed to respond adequately to warnings or accurately describe the incident. The case seeks civil penalties under California privacy and consumer-protection laws; the company’s bankruptcy adds uncertainty about collecting any penalties.

History
10/23/2026
