My acccount was hacked into and stolen from by @contestbuddy and @steem

I am writing this to let everyone know that this platform is something that you should be careful with. My account was hacked into and the hacker claimed my reward and then transferred it to Hive account@contestbuddy. When I check the account contestbuddy was created by Hive account@steem so I want to know who stole my money.

Can someone answer me because I will not lose my money like this - please anyone help me understand this
