value of 73 BTC, worth $4.6 million, originally came from the Whirlpool coin mixer, with some funds bridged to Ethereum and deposited through a phishing Tornado Cash interface

Odaily News: According to on-chain detective Specter's monitoring, the victim claimed that due to a Coldcard hack, funds were transferred from Bitcoin to Ethereum. However, on-chain data shows that the 73 BTC ($4.6 million) originally came from the Whirlpool coin mixer two weeks ago, with some of it bridged to Ethereum and subsequently deposited through a phishing Tornado Cash interface. Two coin mixers were used during the 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 their funds may have been stolen by another threat actor.
