Thank you for your support. Any help or advice is valuable and highly appreciated. I just want to add that the main reason for posting this was to inform other people of the situation and prevent from making same mistakes.
We all know this and you said to prevent same mistakes? I don't understand since you never posted a mistake in the OP, you also said it might be a security breach but the thing here is that the hacker might already hacked you log in. Better store your balances in a more secure wallet, I don't think this statement is new since there are a lot of threads here saying that it ia not safe to store on online wallets or some called it hot wallets.
