What Can We Learn From The Worldwide Cyber Attack


Saturday morning in Australia we learned of a worldwide cyber attack that caused amongst other things , hospitals in the UK to be disrupted when they were unable to access their computer systems as they were ” locked out ” due to ransomware running on their systems.

Are you at risk?

  • If you ignored the March 2017 security update, where the vulnerability was identified and Security Update for Microsoft Windows SMB Server (4013389) which was rated as critical for all versions of Microsoft Windows.
  • If you have not updated your system recently, and I mean “March 2017 or later.”
  • If you are running a version of Microsoft Exchange older than 2010.

So if you’re running Windows 7, Windows 8.1 or Windows 10, and you’ve been updating your system regularly, you are probably not at risk.

According to analytics firm NetMarketShare, only about 7% of the world is at risk for WannaCrypt right now.

So what can we learn:

  1. Patch your systems with Windows update – the attacked computers were running out of date operating systems
  2. Have a backup that can be restored after an attack
  3. Stop opening emails that maybe not for you – when in doubt don’t – if you don’t think it was for you it probably wasn’t – can i make myself any clearer
  4. Be suspicious of attachments – very suspicious
  5. Their antivirus did not save them – which once again shows that you need to rely on your actions – not an antivirus solution
