Piss poor written software
While I don't have experience of specific medical software, I DO have experience of the software required for the laboratory equipment.
A bigger bunch of ham-fisted kak-handed shitty software I have not seen.
They (99% of them) all require admin rights to run, they do not use any form of authentication.
Their library's are so old that they will not run on anything under 5 years old, and they have never been re-written \ patched in their lives.
Some of them look like they were written in the original VB!!
This on equipment that costs 10's if not 100's of thousands of pounds.
The only way to keep these remotely safe is to keep them on a separate VLAN without access to the wild internet... "Oh but we need remote access and it needs to communicate with our licence server"
License server??? it only runs THAT HARDWARE THAT WAS BOUGHT WITH WTF do you need a LICENCE SERVER!!
