Public Health Wales (PHW) has accepted in full the recommendations of an independent investigation which found that simple human error was to blame for the August 2020 data leak that saw the personal data of 18,105 people who had received a positive Covid-19 test made publicly available.
The breach occurred on 30 August when data being entered into the organisation’s Tableau business intelligence platform was published to a live public server, where it remained searchable by anyone viewing the PHW website. During the 20 hours it remained available, it was viewed 56 times.
