Today I checked my wallet and I noticed someone transferred 84(50$) CS tokens from account to 0xd8490b0a7db82be84d99ff6e047ed07769b7a6eb address. I know it is impossible to get those tokens and it is not a lot but I want to know how my account got hacked. Is there any way we could track how the person got my wallet key? Any help would be appreciated.
Edit: I have Zero ether in my account so I cannot transfer remaining tokens to another account. In order to transfer I need to buy ETH. Is it a good idea to buy ETH and transfer to old account then transfer remaining tokens to a new address?
