I just got 0.048049 BTC lost/stolen because I entered my private keys online trying to sign transactions to spend 0.1999 BTC I had stuck in a 3-of-3 multi-sig address. I managed to receive only

0.131 and 0.008 from https://blockchain.info/tx/bcbd90c0a4d198206865b8cccb227d6166d9b78b3c45d4ee66f8d83c6b69422f

and then from the 0.06 (that wasn't created by me), I received 0.011951 from https://blockchain.info/tx/fea862bdc6e827a0b25ad2d53a64cc3b5d408e27011a01adfbef165b643e8219

The remaining 0.0480377 BTC was sent to https://blockchain.info/address/1KT7sG84birTF2YvW5yP7G4NPeMs7Fcdbh and is lost/stolen

Also, they stole ALL of my 0.1999 BCH that was in https://blockdozer.com/address/33RZTwkqqixKySFim1oSXVcFFBAPUiBwLG

2 out of 3 outputs are yours: 3Lzs3s6p (0.131 BTC) and 1MoTG1qn (0.008 BTC)
but the 3rd isn't? however you've received 0.011951 BTC back to your address 3Lzs3s6p
so the thief sent you back 0.011951 BTC and only stole 0.0480377 BTC
this just doesn't make sense, and why wouldn't he just steal all of them at the first chance he got?

how exactly you created the multisig address in the first place? in 2015
why 3-of-3 multi-sig? do you hold all the private keys?
and how did you compose/sign the transaction before broadcasting it?

edit: just noticed... both BTC and BCH transactions used the same tx fee of 0.0009
