How to Protect Against Ransomware

Image result for ransomwareThe NHS has suffered a major cyber-attack that hit hospitals across the country, leading to patients being turned away from A&E.

The attack used a form of ransomware and targeted thousands of organisations in as many as 74 countries. Ransomware is a kind of cyber-attack that involves hackers taking control of a computer or mobile device and demanding payment.

Much like malware and viruses, ransomware can get onto your PC from nearly any source.

Below are some actions you can take to protect yourself from ransomware:

  • Beware of malicious websites, look at the logo, colours, is there anything suspicious about this website?
  • Opening emails and email attachments from people you don’t know, or that you weren’t expecting. If you’re unsure of the content, do not open it.
  • Clicking onto malicious links on social media sites such as; Facebook, Twitter, Instant Messenger chats such as Skype.
  • Often fake emails and webpages have bad spelling, or just look unusual. Look out for strange spelling and punctuation in company names/email addresses.
  • Ensure that no data is stored on your PC only, make sure that data is stored in a central server based location and backed up to external devices/cloud providers regularly. Data should be backed up daily, where possible. Your backups should also be checked and tested regularly.
  • Ensure that you have the latest Operating System (PC or Server) or at the very least having an Operating System which is supported by the supplier, and has security updates applied. Ideally, your OS should be Windows 7 or above.
  • Anti-Virus products are at the latest levels and frequently updated.
  • Users should only have access to the files that they need, ensure that permissions are set correctly.
