I just received an email from someone pretending to be Mt. Gox, addressing me by my (fake) name I used to register for some service that probably had a data leak. The mail invites me to a call that promises new info on the Gox repayment process and tells me to have my account details ready. I suspect that this is some BS, since the sender domain is "mtgox-invite.online". Be aware, everyone.
Good to post it, and have no doubt that this is a scam attempt. If, by any chance, you remember where you put those credentials, then you can probably find which one has the leak. In any case, anything other than the official communication channels is a no-go, and everyone must be aware of it.
