The hackers holding hospitals to ransom

Although we had thought it ‘behind the times’ that the computers controlling our anaesthetic machines were not wifi enabled or network connected - and so would not allow remote upgrading of operating software - following the ‘Wannacry’ ransomware cyber-attack we were relieved and reassured to know that our stand-alone, life-critical systems were safe from harm and safe to use. We now wonder if with anaesthetic machines, it’s best that contact with the ether be restricted to filling of the vaporisers.
