Right... I have 2FA on everything now (I think), but at the time I did not and it really freaked me out.

Doesn't seem like a targeted attack and therefore you probably didn't loose anything, but it could have very much been one.
Who knows… as far as I know nothing was accessed. I added 2FA instantly on everything I could think of on the day of this nonsense. I just couldn’t believe something like that could happen. I had that number for ages.
