Specter flags Coldcard claim as 73 BTC moved through mixers and into phishing Tornado Cash interface

On-chain investigator Specter has raised questions about a claimed Coldcard hack after tracing 73 BTC linked to the case. According to Specter, the person described as a victim said funds were moved from Bitcoin to Ethereum after the incident. But blockchain data showed the 73 BTC, valued at about $4.6 million, had come from the Whirlpool mixer two weeks earlier. Part of the funds was then bridged to Ethereum and deposited through a phishing Tornado Cash interface. Specter said two mixers were used during the transfers. The investigator also said the individual had appeared in Telegram groups tied to private key searching and brute-force cracking. Based on those findings, Specter said the supposed victim may in fact be a threat actor, and that the funds may themselves have been stolen by another threat actor.

Specter says alleged Tornado Cash phishing victim may be a threat actor

On-chain analyst Specter said the source of funds tied to a person who claimed to be a victim of a Tornado Cash phishing site is questionable. The individual had previously said that a Coldcard hardware wallet was compromised, prompting a move from Bitcoin to Ethereum, and that more than 1,000 ETH was later lost through a fake Tornado Cash interface. Specter said on-chain data shows the 73 BTC the user described as stolen, worth about $4.6 million, had actually been withdrawn from the Whirlpool mixer two weeks earlier. Part of those funds was then bridged to Ethereum before being deposited through the phishing site and stolen. Specter also said the same identity had previously appeared in Telegram groups related to private-key cracking and brute-force activity. Based on those details, the analyst said the supposed victim may itself be a threat actor, and the funds in question may have been taken from other attackers.

Specter says claimed Coldcard hack victim story conflicts with on-chain data

On-chain investigator Specter said the account given by a supposed victim who claimed to have moved funds from Bitcoin to Ethereum after a Coldcard compromise does not line up with blockchain records. According to Specter’s monitoring, the 73 BTC involved, worth about $4.6 million, had originally come from the Whirlpool mixer two weeks earlier. Part of the funds then moved across chains to Ethereum and was deposited through a phishing Tornado Cash interface. Specter added that two mixers were used during the transfer process. The individual was also found in Telegram groups focused on private key searching and brute-force cracking. Based on those findings, Specter said the claimed victim may in fact be a threat actor, and the funds may themselves have been stolen by another threat actor.

Samourai Wallet CEO Sentenced to Five Years for Unlicensed Bitcoin Mixing Service

Keonne Rodriguez, CEO of Samourai Wallet, was sentenced to five years in prison on July 2, 2026, for operating an unlicensed Bitcoin mixing service that laundered $237 million. The service, including Whirlpool and Ricochet, processed over 80,000 BTC ($2 billion) and generated $6 million in fees. Rodriguez and CTO William Hill pleaded guilty to lesser charges of operating an unlicensed money transmitting business, avoiding money laundering conspiracy charges that carried up to 20 years. The case is part of a broader DOJ crackdown on crypto mixing services, following the conviction of Tornado Cash co-founder Roman Storm. Prosecutors highlighted that the pair actively promoted criminal use of the wallet, undermining trust in digital assets.

Samourai Wallet Co-Founder Bill Hill Sentenced to Four Years for Bitcoin Money Laundering, CEO Gets Five Years

On November 19, William 'Bill' Hill, the 67-year-old co-founder of Bitcoin mixing service Samourai Wallet, was sentenced to four years in prison for operating an unlicensed money transmitting business that processed over $237 million in criminal proceeds. His co-founder and CEO Keonne Rodriguez received a five-year sentence earlier this month. The platform's Whirlpool and Ricochet services were used to obscure money from drug trafficking, darknet markets, cyber intrusions, fraud, murder-for-hire, and child pornography. The case highlights the U.S. Department of Justice's intensified crackdown on privacy-focused crypto tools, following similar prosecutions of Tornado Cash developers.
