I did a similar stunt with an old PowerBook where I electrically disabled the WiFi/Bluetooth so it wouldn’t be online unless I plugged in Ethernet, generated keys, and played around with mining. This was back in 2010 when this was all just basically toys for fun. I also encrypted it all with FileVault.

Then I forgot my pass phrase and have never been able to recover any of it. I don’t even know how many btc were mined/lost.

Before anyone asks, no, there aren’t any usable exploits / vulns found for the encryption methods used. And from what I can tell the coins in question have still sat frozen for going in a decade and a half now. I suspect many other hackers did the same thing…

Wasn't there an offline wallet that used a poor algorithm to develop seed phrases, and thus someone stole all of those coins a couple of months ago?

bitaddresses .org? If the JS code was defective, the coins can still be stolen later if the hacker can recreate the keys by going through the small key space, despite the coins being created being offline.
