Half a million Britons’ medical data were offered for sale on Alibaba in major UK Biobank breach

UK Biobank informed the UK government that health data from roughly 500,000 volunteers was listed for sale on Alibaba; the listings were removed after intervention by the UK government, Alibaba and reportedly the Chinese government. The dataset is described as de-identified and not containing names, addresses or contact details, and officials say no sales are believed to have taken place; government sources criticised the Biobank's security arrangements.
