Yesterday someone changed my password and took everything from my character

I only got the password of this account and I did not give it to anyone .....

I was in Aden (server: USSR[x15]) with me dwarf when I saw my character (main) to walk - I could not believe not me, but some others

.
I saw everything that happened and I could not do anything - I tried to log on but I could not

I have some screenshot - I hope to help solve the case....
Please help
