Joint investigation by Canada and U.K. says 23andMe failed to protect customer data
UNITED KINGDOM, JUN 17 – The UK Information Commissioner's Office fined 23andMe £2.31 million for failing to protect genetic data of 155,592 UK users during a 2023 credential stuffing cyberattack.
- The UK Information Commissioner's Office fined 23andMe £2.31 million on June 17, 2025, for failing to protect personal and genetic data during a 2023 data breach.
- The breach started in April 2023 through credential-stuffing attacks that compromised about 14,000 accounts, resulting in the exposure of personal information connected to approximately 6.9 million individuals worldwide.
- Investigations by UK and Canadian privacy regulators found that 23andMe had inadequate security systems, delayed response, and insufficient safeguards despite warning signs before the breach.
- John Edwards, the UK Information Commissioner, described the incident as a serious violation that revealed confidential personal details, including genealogical data and medical information, affecting thousands of individuals across the UK.
- Following bankruptcy filing earlier in 2025, 23andMe is set to be sold for $305 million to co-founder Anne Wojcicki's nonprofit, which has pledged stronger privacy protections moving forward.
