Overview of the incident
The UK government has confirmed that health information linked to around 500,000 participants of the UK Biobank research project was found listed for sale on an online platform associated with Alibaba in China. The listings were discovered and removed after being reported by the charity that manages the database.
Officials clarified that the exposed dataset did not include direct personal identifiers. It did not contain names, home addresses, phone numbers, NHS numbers, or full dates of birth.
However, the dataset did include sensitive health and demographic details such as:
- Age range and birth month and year
- Gender
- Socioeconomic background
- Lifestyle information
- Biological and health measurement data
Even without direct identifiers, experts note that such detailed health profiles still require strong protection due to potential privacy risks.

UK Biobank stated that it is actively investigating the incident and working with UK and Chinese authorities, along with Alibaba, to understand how the listings appeared.

The Information Commissioner’s Office also confirmed it is reviewing the case.
