A major data security scare has hit the UK after health data from nearly 500,000 participants in the UK Biobank was found listed for sale on Alibaba in China.

The UK government confirmed the breach, saying the data included sensitive details such as age, gender, lifestyle habits, and biological information. While officials insist the dataset was anonymised and contained no direct identifiers, the incident has raised serious concerns over data misuse and global research security.

Authorities say the leak was not caused by a cyberattack, but by researchers who misused legitimate access—sparking outrage and calls for stricter oversight.
