You may have read in the news about a large scale cyber-attack involving the WannaCry ransomware (a malicious program that locks a computer's files until a ransom is paid), which targeted thousands of organisations in as many as 150 countries.

While there was no impact to Nationwide, and our members’ money and data remains safe and secure, we wanted to make you aware of this threat and what steps you can take to prevent ransomware from infecting your personal devices.


  • Keep your devices updated with the latest software updates
  • Make sure you have anti-virus software which is kept up to date
  • Protect the information and files stored on your devices, by backing up the information on a separate system, for example an external hard drive
  • Exercise caution when opening unsolicited emails

Remember that emails from Nationwide will always include your postcode at the top of the page, providing you have a valid UK postcode.
