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
- Don't you have a hardware wallet or Trezor? because if you don't have that, it will come out as if you are careless. 11 BTC is not a small amount, to be honest. If I had that amount of bitcoin, for sure, I would buy a Trezor and a hardware wallet to make sure my bitcoin was safe.
Now, if you have a Trezor or any hardware wallet, the question will be: how did that happen? because you're the only one who knows seed phrases, right? You also did not mention whether your 11 bitcoins are stored in a noncustodial or hardware wallet.
