I got a very similiar /whisper message a few days ago. But as soon I clicked a bit (not logging in of course, because I m always logged in the real offical forums), it turns out, that it was totally a scam. Even the link itself should proof enough, that something is not right.

The same message was posted in the novice chat weeks before.

It may sound hard, but never trust tells with a link in it.

PS: Hackers cant get around the 2FA, except you let them in ; )
