Disclosure of Vancouver Patient Medical Data Pager Breach
In November 2018, Open Privacy staff members discovered data from patients admitted to Vancouver area hopsitals was being broadcast unencrypted over paging systems, making them openly available to anyone in the Great Vancouver Area with minimal equipment and expertise.
The data being broadcast included the patients name, age, gender marker, diagnosis, attending doctor and room number. Other broadcasts regarding medical tests such as x-rays are often associated with a patients last name or medical number, making their progression through hospital systems trivial to piece together. We have been able to confirm the authenticity of this data by cross-referencing this data with a public obituary.
Open Privacy immediately began responsible disclosure of this issue with Vancouver Coastal Health. However the disclosure was initially ignored, and it wasn’t until Open Privacy contacted members of the media and the Office of the Information & Privacy Commisionor in B.C. that VCH began asking technical questions regarding the breach.
This page documents the timeline and impact of that disclosure.
