Yesterday I lost 11 BTC from my Bitcoin Core 25.0 wallet.  The wallet wasn't open at the time.  I don't know how it happened. Lots of emotions right now.  

edit to add:

Definitely not my wife. We live in a rural setting. She doesn't have the computer knowledge to even launch the wallet. This was an external hack.

I first noticed when I logged into Koinly and saw my BTC balance was reduced.  I then launched Bitcoin Core and it was about a week behind.  Showed my 11btc as it updated, then hit the date of the hack and it went to zero.  Wallet is encrypted and appears to work fine. PC is turned off now and hard drives will be wiped. This definitely sucks, but not the end of the world.  Opportunity for others to learn or be reminded from my mistakes.

Also, the coins have not moved from hacker address
