California Attorney General Rob Bonta has said he will sue DNA testing firm Chrome Holding following a probe on Thursday, alleging its predecessor company 23andMe failed to protect sensitive customer data.
Bonta said the failure resulted in a 2023 data breach which exposed genetic predispositions and risk factors of nearly seven million users, plus information about biological relatives, ancestry, and ethnicity.
"Our investigation found that the company failed to take basic steps to protect users' data," said Bonta, who added 23andMe "lied to consumers about the severity of its 2023 data breach."
The BBC has requested comment from Chrome Holding.
The company was rebranded after 23andMe filed for bankruptcy last year.
Bonta also alleges the subsequent sale of 23andMe user data on the dark web by threat actors specifically touted that it belonged to Asian American Pacific Islanders (AAPI) and Jewish users.
"This is disturbing and incredibly dangerous" given it occurred during a period of "mounting anti-Asian American and Pacific Islander and antisemitic hate and violence," Bonta said.
Users were targeted by a so-called "credential stuffing" attack in which hackers used passwords exposed in previous breaches to access 23andMe accounts for which people had used similar credentials.
The 2023 data breach has resulted in international regulatory scrutiny for the company.
The ICO said personal data of 155,592 UK residents was accessed.
The company has said it has "made several binding commitments to enhance protections for customer data and privacy."
The ICO's probe was conducted in coordination with Canada's privacy commissioner and found 23andMe violated UK law by failing to implement appropriate authentication and verification measures for customers during its login process.
At the time, some users expressed concern over the prospect of insurance companies purchasing their data and using it to determine whether to provide coverage.
23andMe was cofounded by Anne Wojcicki, sister of the late YouTube boss Susan Wojcicki and ex-wife of Google co-founder Sergey Brin.
The company once counted Snoop Dogg, Oprah Winfrey, and Eva Longoria as customers and saw its share price top $300 at its peak before crashing in 2024.
