Someone’s hacked into her email - she needs to change it ASAP.
It happened to a relative of ours - someone had got into his email, found out from reading emails that he was going to be on holiday and out of contact for a couple of weeks. Scammer then emailed his financial adviser, asking him to transfer a major sum to a completely new account. And not to bother trying to contact him, he was away, etc.
And the idiot FA actually did it!!
He did get the money back eventually, presumably from the FA’s insurance, though whether anyone would be prepared to insure him again after that debacle, I doubt.
We were later told that after any such request, any reputable FA would make several separate checks before transferring even a tenner.
