Cybersecurity expert and host of BBC One’s Scam Interceptors, Nick Stapleton, advised people to think about what they shared on social media.
“If you’ve got a social media account that’s not protected and has things like a picture of your dog with its name underneath, or of your family with their names tagged, scammers can use those to get past security questions,” he said.
He also recommended adding a PIN number to the Sim card, which can be done in a phone’s settings, and the use of authenticator apps to generate random codes, instead of ones sent by text.
