Gregory's ServerPSA:
Scammers are targeting people's MyGov accounts.
I just received email that said I'm locked-out of my MyGov account.
If you receive email like this, do not click on a link! If the email came from a scammer, they'll try to trick you into giving your password.
Instead, to the MyGov website, try to login, and if necessary do a password reset. Then go the the "My Account" section and make sure you have 2 Factor Authentication configured.
Presumably, a scammer got my email address and tried to login with it, and after failing a few times the system locked my account. All sorted-out now.
