Yes that was me. I couldn't figure out where the hack came from. I wasn't sure if it was something to do with Yobit or whether it was the GPU wallet I had tried to install. Somebody named 'lucky89' (something like that) told me they had the same windows wallet and that it was working just fine, so i started doing some google searching to try see if other people had lost coins on the exchange. It was only when I saw the dev's post on iBankCoin, that I started thinking that maybe the hacker had compromised the download link to the windows wallet.
