 You are absolutely right, still proving ownership is going to be difficult. Especially in this case. Because holding the private key isn't enough anymore, hope they keep their coldcards as evidence.

    title: How do we know it was an attacker and not the owner moving their coins?
    body:
    That’s the part I’m not fully convinced about.
    
    I understand the first wave was clearly an attacker. But once Coldcard users heard the news, wouldn’t an attacker sweeping funds and an owner moving all of their funds to a safe wallet look pretty similar on-chain?
    
    Unless the owner confirms the transaction was unauthorized, shouldn’t some later cases be called suspected thefts rather than confirmed attacks? And even then, proving ownership seems difficult once the attackers also has the private keys.

    Probably a lot of owners don't (didn't) even know about it, not everyone is on Reddit or other socials.
    
    Also, the attacker is using one wallet AFAIK.

    I think this is an interesting take. all you can do on chain is prove it moved here to there on a block. whether it was stolen or moved by the owner seems to be a he said she said argument. I will say for a fact the tales of people losing their savings has gone through the roof. I find it odd that the number of people on this sub would have such disproportionate bad luck. Maybe it’s just people jumping on for upvotes taking advantage of the situation.

    Alright that clears it then. I thought it was multiple attackers in the later waves of attacks.
