Yeah my legendary account was hacked this morning as well. I've had many bitcoin addresses and I don't think I have one associated with that account.
I had an email address in the account but I guess you only need the account password to change that. Looks like the hacker got my 4 year old account. Shame.. It was a recent ICO I signed up to.. So many scammers out there is sad.
So did you retrive your account? Is there any way?
