I find it amusing how all the news reports gloss over the fact that the FBI somehow got access to the wallet’s private key. I’m also wondering why the hackers didn’t request payment in a currency that’s more difficult to trace.

If you do a memory dump on a hypervisor you can get all the memory of the VMs on that server including keys as they are being used.

More detail on how they managed to get access to that password/private key? Edit: I found the bitcoin address https://www.blockchain.com/btc/address/bc1q7eqww9dmm9p48hx5y...

The most plausible theory I've heard is that the attackers used a BTC tumbler that was a honeypot controlled by feds.

But who knows, maybe the FBI has a quantum computer we don't know about.

Guessing that it is malware or wallet vulnerability . I don't think it was server being siezed

If it was not hacked then I believe the implication is that the key was cracked. Presumably, via brute force capability of unknown nature or a weakness in Bitcoin not known at this time.

More likely typical law enforcement methods than technical: they seized equipment with key, accessed an account where the key was transmitted (like email or a phone), wire-tapped an insecure channel, or strong-armed a defendant into revealing it.

ie, a $5 wrench

I think it's that BTC is easier to get victims to buy without oversight. There are Bitcoin ATMs. Buying Bitcoin from an ATM is like sending money via Western Union, but without the teller there to spot someone looking like they're under duress. As for anonymity on the receiving end: the BTC can always just be exchanged for a more anonymous currency like Monero. You might think that'd require the criminal to KYC to a…

KYC?

> If it was not hacked then I believe the implication is that the key was cracked. Is anyone here willing to say they believe the key was cracked? Seems extremely implausible to me.

I’m open to alternatives, though I have felt that the response to this involved the highest level cyber warfare capabilities of the United States.

I would not be surprised to find out the US has this capability.

I hope they start seizing Ethereum because it would show how not decentralized and not secure proof of stake system is.

If they get hold of your wallet's private key, they can seize it in any system.

They are more than welcome to do it if I break any law but I have to say you I'm not. By the way they can seize funds from your or my bank account as well there is nothing special about "crypto" coins they are not outside the law code is not law.

Yes, it's a dark pattern in journalism. They hint at causation while having plausible deniability. Used to bother me too when I checked Yahoo Finance, every other day the market would be up/down "as" whatever happened that day that might have anything to do with the economy.

To be fair, it's usually pretty hard to say why stock prices change. Even with hindsight. Mostly because anticipation is so important.

So: absent proof don't say anything.
