It’s an unfortunate lesson but I know that there are always people looking to steal folks funds in one way or another. I would also add in the recommendation to use the brave browser which has privacy and security as the most important features, and the keychain app if you don’t use that yet. That way you only have to enter the keys to get into the account the you never have to enter a key again.

Hopefully you can get some of the funds back! That’s a tough loss!
