Specter Discloses Coldcard Incident Doubts: 73 BTC Mixed Then Flowed into Phishing Tornado Cash Interface

According to on-chain detective Specter's monitoring, the victim claimed that funds were moved from Bitcoin to Ethereum due to a Coldcard hack. However, on-chain data shows that 73 BTC (worth $4.6 million) originally came from the Whirlpool mixer two weeks ago, with part of it bridged to Ethereum and subsequently deposited via a phishing Tornado Cash interface.

Two mixers were used during the relevant fund transfer process. The individual was also found to have appeared in Telegram groups involving private key searches and brute-force attacks. On-chain detective Specter stated that the victim may be a threat actor, and the funds may have been stolen by another threat actor.
