ChainCatcher news, on-chain detective ZachXBT posted on X, pointing out that the wallet addresses corresponding to approximately 127,000 bitcoins (about $14 billion) announced to be confiscated by the US government had already been identified as having private key vulnerability risks in a security research report (Milky Sad Report) two years ago.
ZachXBT stated that these addresses are now claimed by the US government to be "taken over and under its custody," raising concerns about how they were obtained. When a user asked whether the funds had been transferred to a more secure wallet, ZachXBT replied: "Unlikely, it seems more like someone 'hacked' them back for the US government." This comment suggests that the related BTC may not have been acquired through conventional judicial means.
