My wife's contacts have been receiving spam emails from email addresses with different domain names but the name infront of the @ symbol is the same in all cases. It is the same as her yahoo account. At the bottom of the email it contains the proper email address of her yahoo account.
Can someone tell me how this is likely to be happening? Has someone managed to get into her email account? How have her contacts been obtained? What would explain this? Is there a virus on one of her devices?...or has she managed to give up her contacts somehow? Have the contacts been sent to someone online and added to a spam database....so all her contacts will receive spam forever.
Next, what do we do to stop it from happening?
She uses PCs, an android phone, an iPad and a Macbook.
Thank you for your help
