Guidance on protection against ransomware

  ,

📥  Security

Due to the ransomware attacks on the NHS and many other organisations as reported in the world media, we have provided some guidance to protect your personal devices (including ones you have at home) against similar attacks. If you have a University-owned device then please contact us for advice.

Windows XP
We recommend that you obtain the latest version of Windows as Microsoft no longer support this. However, they have provided an emergency update to protect your device against this particular attack.

If you are not able to obtain the latest version of Windows, then you need to run Windows update to ensure your system is up to date.

Ensure that you have antivirus software installed and that it is up to date. If you do not have antivirus software installed then we recommend Sophos which is offered to staff and students for free.

Windows 7/8/10
Run Windows update to ensure your system is up to date.

Ensure that you have antivirus software installed and that it is up to date. If you do not have antivirus software installed then we recommend Sophos which is offered to staff and students for free.

macOS
If possible, ensure you have upgraded to the latest macOS. 

If you are running Bootcamp, this will need to be updated too.

Check and run Mac software updates. 

Ensure that you have antivirus software installed and that it is up to date. If you do not have antivirus software installed then we recommend Sophos which is offered to staff and students for free.

Linux
Update your system to the latest version. 

If you are running a virtual machine this will need to be updated too.

Ensure that you have antivirus software installed and that it is up to date. If you do not have antivirus software installed then we recommend Sophos which is offered to staff and students for free.

iOS
Update your system to the latest version.

Ensure that you have antivirus software installed and that it is up to date. If you do not have antivirus software installed then we recommend Sophos.

Android
Update your phone to the latest software version. See your phone manufacturer’s website to find out how to do this.

WannaCrypt Ransomware - please be vigilant

  ,

📥  Computing Services, Security

You will be aware of the news reports of ransomware attacks on the NHS and many other institutions around the world.  Ransomware attacks are mainly launched via email and are a major threat to our data.

To protect against these, the University of Bath relies on a layered approach to protect our systems with regular patching, anti-virus, firewall protection and mail filtering.  Updates to protect University systems against the vulnerability exploited in the latest attacks were tested and released to our systems and signature updates for the current attack were made available from our vendors.  Support teams are working to check that all updates have been deployed successfully and ensure that our systems are fully protected.

Ransomware does need someone to open the booby-trapped attachments so everyone should take care with emails containing attachments or links. An email may look genuine but can be spoofed. You should ask yourself:

  • Am I expecting an email from this organisation?
  • Have I actually purchased or used the service being referred to?
  • Am I confident that the attachment is safe?

Even if you choose to open the attachment:

  • Never tick/check enable macros on attachments, unless you explicitly need to and trust the sender. If in doubt contact Computing Services.
  • Don’t run a program if you don’t know where it has come from and haven’t chosen to install it yourself.

If you are in any doubt, the best way to contact us is at http://go.bath.ac.uk/it-help-form. If your enquiry is urgent then you can contact us on x3434.

Personal and home computers need to be protected as much as University systems, so make sure you run system updates and check your anti-virus is up to date the next time you use your computer. For more information see the article on the malware from Microsoft.

We also offer advice on dealing with fake and phishing emails on our website.
