The National Cyber Security Centre (NCSC) offers the following advice to help protect yourself online:
Turn on two-step verification
Use a password of three random words
Create a separate password that you only use for your main email account
Update the software and apps on your devices regularly
Save your passwords in your browser
Back up important data
Scammers can now clone the phone numbers of organisations they want to impersonate. Even if the number on your caller display matches an official number, it might not be real.
If you’re calling a company back, find the number yourself and don’t use the number they supply. Using the 159 service is the safest way to contact most UK banks after a supposed fraud call.
