Was My Desktop Wallet Hacked?

[rapture333]

So, this past weekend I decided to send some BTC over to Gemini to withdraw and trade into Ethereum. This was this past Saturday night, December 9th. I access my desktop remotely via Teamviewer to get the coins out of my desktop wallet and sent over. The transaction completed successfully, I had to input my wallet password for each transaction for a total of two transactions for two bitcoin sent to Gemini at a rate of one each. When I came home after the weekend away from my desktop, which I kept running and no-one home at the time, I notice that my remaining balance was gone!? I checked the address the BTC was held which is 1AUyoMFrcjo4DybZiS2nZn6M4P5NfDsxho, https://blockchain.info/address/1AUyoMFrcjo4DybZiS2nZn6M4P5NfDsxho, and noticed that in the same block the remainder of my BTC was sent to https://blockchain.info/address/1Lmdg8LLBG8gK9QU7WZHDmVoupV9UF2y7G and partially to https://blockchain.info/address/1Kt4GBMumvH1vzKygeJuSixTQJLoJvA2d4 in another block, which I did not initiate!!! How could this have happened! I have heard of keyloggers/trojan horses in the past?? Is there something I am missing here or did my BTC get stolen? Any help or understanding would be appreciated.

Sincerely,

First, buying ETH is retarded.

Second, bitcoin wallet connected to there internet for nothing for days and connected to remote programs like teamviewer...

Third, doing 30-50k$ transactions remotely and entering your passphrase remotely...

Are you serious ?

I feel for your loss but your security was horrible.

is this first time you use dekstop wallet? because impossible to hack dekstop wallet if you install antivirus and used 2fa for transaction. and why you use team viewer to acces your wallet?

Desktop antivirus and 2FA aren't infallible though. Desktop antivirus is essentially just playing catch-up with security threats from various online sources and it isn't going to protect you against everything; mostly just malicious files that it encounters or patterns in code that are shown to be malicious in the past. 2FA can be beaten provided they know your name and your phone provider, they can snake a SIM card copy and that can make your 2FA useless, but it is unlikely that someone will go tot hat trouble to go after your wallet unless they see a lot of value in doing so.

Or they can just go after the wallet.dat and restore that information.

I was away from home and wanted to be able to use my wallet if I needed it seeing as I trusted my home PC more then a web based wallet... I didn't know Teamviewer would be so insecure? But the thing is my wallet doesn't show the transactions!? It's like someone took my wallet.dat and waited for a keylogger for the password, this makes no sense. My password was encrypted, so they would have to go pretty damn far to do this.
