Providence Health & Services, a health system located in Alaska, California, Oregon, Montana and Washington, has reported that its paging system has been breached.

An unauthorized individual was able to intercept pages between healthcare workers and post the contents of the pages online between October 25 and October 28, 2016. The pages included patients’ names, room numbers, medications, dates of birth, medical record numbers, symptoms, diagnoses and medical procedures.

It is reported that the paging system was not secured using encryption technology, and like all devices connected to the Internet, it is hackable if it is not secured.
