Computers which coordinate NSW's ambulances all finally returned to
normal Monday afternoon after a virus forced staff to shut them down for
more than 24 hours.

One source who used to work closely with the Computer Aided Dispatch
System (CAD) system told this website that the ambulance service was
"very protective of it when I worked there" and that the virus likely
infiltrated the network via an infected USB as the network was a
"physically isolated network" with "no internet connection of any kind".

"The only way a virus could get onto it would be via physical access –
someone with the virus on a USB key," the source said. "It's probably
just someone [who] has plugged in an infected USB and it's infected a
few Windows PCs in the office."

Those claims were put to the NSW Ambulance Service but it declined to
comment on them.
