I got a weird email this morning that looked like it was from my mum but clearly wasn't. Just had a dodgy link in it. On checking the sender address it's her name but not her email address. I've blocked the dodgy email address on my email. Told my mum but as it's not actually come from her account does she need to change her password? Worrying that the scammer obviously knows my email address and both our names but doesn't look like they've actually accessed our accounts. Should I do anything else?!
