I am not trying to spread speculation, but please can someone answer how else this could happen? Whenever I've peeled a coin, it is completely destroyed. It looks nothing like the coin pictured. Compare to the other 2013 Cas Brass pictured - that one looks normal.
The hack was far from perfect, you could see the places where the needle penetrated the holo with the naked eye.
This is why I recommend to inspect the holo with a magnifier or microscope if you buy from a none trusted source.
Afaik the lazer edged holo on the Cas 1 BTC silvers has never been hacked, mike did the lazer edging as a respond to defcon, I am surprised not more coin manufacturers have adopted this technique.
Pretty sure the etched privkey can be seen under X-Ray without peeling.
If that is true than all nastycoins should be considered compromised, I wonder if OGnasty took any steps to prevent this.
The guy that made those wallets that were almost impossible to destroy, and bip38 encrypted xrayed his and the private key couldnt be read, They had a really weird name, and if someone could guessed the inspiration of the name they got one free. Can anyone recall?
They were the KEYOIS capsules
