So in the first months of 2021 the owner of UTXOs of this address apparently had access to this address' private key and the other involved inputs in above transactions.



I'm not convinced because a Bitcoin Core wallet uses a lot of keys and public addresses, not just a single one. And naming a public address with a suitable balance isn't hard at all.

Your passphrase hints for the Truecrypt container are rather insufficient. My question would be: why didn't you document such an important secret?

As n0nce points out, having the hashes isn't quite enough. An attack to crack the Truecrypt container passphrase would also need details how Truecrypt processes the passphrase to get to hash digests. Well, likely hashcat or similar tools know how to deal with cracking Truecrypt containers.

And then if someone manages to crack the Truecrypt passphrase: what about the contained wallet.dat file. Is this protected by a passphrase, too? Is the Bitcoin Core wallet.dat passphrase known?
