Specter reveals doubts about the Coldcard incident: 73 BTC flowed into the phishing Tornado Cash interface after mixing

According to on-chain detective Specter, the victim claims to have transferred funds from Bitcoin to Ethereum due to a hack on Coldcard. However, on-chain data shows that 73 BTC (worth $4.6 million) originally came from the Whirlpool mixer two weeks ago, with some of it crossing over to Ethereum and subsequently deposited through a phishing Tornado Cash interface.

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