My wife has an old gmail account which is her first initial and last name. She set up email forwarding to another account several years ago promptly forgot about it. Unfortunately she picked her original password before I introduced her to password managers and so now her original account has been taken over by someone. Interestingly enough that email forwarding she set up still occurs and she has all of the received email for her attacker(s) including all the security notices. I figured it would be a bunch of people emailing angry that they received spam from the account. Instead it’s a bunch of disjointed English talking about the weather - back and forth messages such as “in Tuesday we will have windy”. There are several iOS devices now logged into it. I am baffled yet insanely curious. Unfortunately even though this email forwarding has been set up for more than a decade, googles automated account recovery does not recognize her request and we can’t get the original flast@gmail.com address back. Anyone at google have thoughts? I can drop my personal contact info if so.
