Canadian privacy & access decisions

This joint investigation by the Privacy Commissioner of Canada (OPC) and the UK Information Commissioner (ICO) examined a significant data breach at 23andMe, which affected nearly 7 million customers globally. The investigation found that 23andMe failed to implement appropriate safeguards to protect sensitive personal information, including genetic data, from a credential stuffing attack. Furthermore, the company's notifications to both regulatory bodies and affected individuals were found to be inadequate in content and, in some cases, timeliness. Although contraventions were found, the issues were deemed resolved due to significant security improvements made by 23andMe.

• Adequacy of safeguards to protect personal information, particularly genetic data, from credential stuffing attacks.
• Timeliness and completeness of breach notifications to regulators and affected individuals.
• Risk of harm to individuals due to the sensitive nature of compromised personal information.
• 23andMe's assessment of and response to the identified security deficiencies.
