Not trying to joke around or anything. But could this be a 'lost my Monero in a boat accident' kind of 'hack'? I can not wrap my head around how this could have happened. Unless lukedashjr's way of storing his balance was mediocre.
The only way I can think of this happening is in a non-standard storage configuration:
- PGP key is used to encrypt crypto multiple Bitcoin private keys
- To spend the bitcoins, the password of the key is entered, and a transaction is made (by hand??)
- Hacker steals PGP key and message, and places a keylogger to get the password. Then they can swipe the coins.
Keep in mind I am still assuming at this point, this is probably NOT how he actually set up his cold wallet.
