Fact Check
The core financial facts of the claim are strongly supported: the $6.7M total loss, the specific assets (ETH, BTC, cbBTC) withdrawn from Kraken and Coinbase, and the $5.3M moved to Tornado Cash are confirmed consistently across the Specter original post, Wu Blockchain, PANews, Odaily, and CryptoNews.net. The claim accurately reflects the initial reporting from Specter Analyst as cited by FinanceFeeds. However, confidence is reduced to medium because: (1) the 'physical attack' attribution is described as 'suspected' even in primary sources; (2) CryptoNews.net reports that Specter later revised or walked back the physical attack characterization, leaving the exact attack vector uncertain. The financial figures themselves appear reliable; the physical attack framing is the uncertain element. The claim as worded ('suspected') is appropriately hedged and consistent with the primary source language.
Summary

A high-net-worth investor holding assets on Kraken and Coinbase is suspected to have lost about $6.7 million in a coercion attack, according to Specter Analyst monitoring cited by FinanceFeeds. The reported withdrawals included 1,554 ETH, 10.5 BTC and 34.1 cbBTC. More than $5.3 million of the stolen funds was subsequently sent to Tornado Cash. The case expands on earlier reports focused on ETH withdrawals and highlights the risk that crypto losses can stem from physical coercion as well as online compromise.
