Ask HN: Google warned me that a state organized hacking group targeted me

Has anyone of you guys gotten that message?

I'm still not sure why they targeted me nor how? I'm neither famous nor a journalist or blogger or scientist or something like that.

Nonetheless,what can I do to find out how they tried it? Or if they broke in or if my network is comprised?

And what can I do to prevent in future? Beside 2fa.
