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.
