There's too much speculation for my taste due to lack of details also in the
decrypto.co article.
No details what kind of wallet and what wallet software was involved and so on and so forth. Others and my "educated guess" is, they cracked a wallet encryption password. Unfortunately it's not more than a guess, because of lack of details. It's probably the least exotic guess or wild assumption.
What I find interesting, if the assumption holds water, is that the twelve wallets involved don't seem to share some wallet encryption passphrase similarity, which is not so common (well, it strongly depends how knowledgeable the creator is about password strength and security).
Collins created 12 wallets to store his growing Bitcoin fortune and recorded the private keys in a document hidden in a fishing rod case at a rented property in Co Galway. In interviews with gardaí, he claimed he never saw the case again after a break-in at his home, though reports indicated a clear-out of the property after his arrest may have resulted in the loss. The original seizure in 2019 was valued at $61 million (€53 million).
Apparently, the 12 wallets are private keys contained within a document. document was apparently password encrypted, and the government cracked the password to access the private keys.
Doesn't make much sense to me what the article says. Why would someone expose and record the private keys? It makes no sense if you don't use BIP38 encryption with a paperwallet e.g.
I don't know. Your conclusions seems a bit too far fetched for my taste. If it were like you say, the government would've gained access to all 6,000
BTC, not only to 500
BTC of the one wallet they cracked. Or am I missing something?
One thing to learn from this: you'd better have redundant secure backups of your wallets at at least two different places.
