UK BIOBANK DATA REPEATEDLY LEAKED ON GITHUB

A privacy researcher monitoring Digital Millennium Copyright Act notices found that sensitive UK Biobank data has been repeatedly uploaded to GitHub by developers across 170 accounts worldwide. The instances represent the latest in a series of data handling issues for UK Biobank, a repository of health records and genetic information from 500,000 British participants used for medical research. The leaked repositories contained portions of the biobank's dataset, which researchers access for studies but are bound by data usage agreements. The repeated uploads suggest either accidental commits or misunderstandings about data sharing restrictions. GitHub has been removing the repositories following takedown notices, but the pattern indicates a systemic problem. Researchers and the institution have published commentary in the British Medical Journal highlighting the governance gaps. The exposures underscore broader challenges in managing sensitive health data as research becomes increasingly collaborative and code-sharing platforms grow more prevalent in academic work.
