Forgot to add, escrow.ms, that this is my address:

https://blockchain.info/address/3ARF2FPQqvCccoFyzHxQyK3QCZ3DMCPNa7

and 3AAmK2ybNLoAtiK8sQXkW3TLE7ZACAMTRD  is an address I used for Quadrigax exchange. Yet I have only transferred a small amount to them.



Unless I am missing something, History>right click> details on the transaction gives me the info.

None of the addresses look familiar.

Just as a background filler each time I plug in my USB I chose "Try Ubuntu without installing" option Then I update, upgrade Ubuntu, install python and then Electrum, enter my seed etc.

I never have used my wallet.dat from my SD card since creating my Seed.

Yes, I am using a MultiSig wallet. I will try that

My Windows watch only wallet is ver 2.8.3. I have left my USB in my laptop while there was 0 btc in my wallet overnight. But not for any extended amount of time during these "hacks". My wallet.dat is stored on a separate SD card. Seed is stored at my office locked drawer and home(no one at home is that tech savvy enough to do this).

Ubuntu version of Electrum I install is 2.9.3. https://electrum.org/#download

Could the difference in version numbers lead to this?

I am pretty sure my wallet got hacked.

I followed the Newbies guide to Cold Storage posted on this forum:  https://bitcointalk.org/index.php?topic=1689727.

Basically, uploaded ubuntu.exe on a USB stick and loaded that each time I needed to send btc. After getting my seed, I created a watch only wallet on my Windows. I would have to install Electrum each time on my ubuntu, but did not mind, since i thought the security was worth it.

Anyways, I sent two small amounts to my Kraken account to test. Each time more btc was sent than I had entered.

After confirmation, I pulled up the history details and noticed different addresses along with the Kraken address, far in excess of what I had sent.

Should I delete my wallet? How do I secure my wallet in the future?

Installing on windows 10 to create a watch only wallet. After running the executable and clicking on the app. It won't open. In the Task Manager, the exe file is running. Any suggestions?
