Odd one, this. My wife has just had a reply in FB messenger, to a message that she apparently sent at 7:30am to a business selling some sort of fancy dolls, asking if one of them is still available. She did not send this message!
We don't seen any evidence that she's been hacked, and my first thought was that it was a pocket-dialling type episode. But it seems a bit too complex to have happened by chance - the messenger group has been given a name and a photo.
Planning to simply change her passwords and keep an eye on things. Is there anything I'm missing?
