I never used my Private Key which is printed since I created my account!
I Just used my active for transfers and every day I use Post key. I keep them in a pen drive encrypted and I use a Mac Book Pro, not windows which is hard to be hacked, but not impossible.
So I really don't know what happened to my account today earlier. After my keys were not working I tried to put my owner key in login to change and even my owner key was hijacked :=/ My owner key is printed since I created the account, so How could someone hijacked even my Owner key? An internal problem? I don't know.
I'm awaiting the recovered link from steemit and will update here later.
PS: I hope can increase safety measures with 2FA or so with more people coming now.
