HELP - Somebody Have stolen my Scorum coins and transfer to his openledger account!

Recently I had 1.53 Scorum coin in my wallet and yesterday I didn't login but someone withdraw all my Scorum coin to Openledger with memo number0.

Please, help me secure my account and wallet and tell how can I secure my Scorum account.

I still have 50 SP in my account and I'm working hard to make Scorum a better place but there are still thieves on the platform.
