According to Arkham Intelligence data, the hacker linked to the Poloniex cyber attack has moved 100 ETH in 11 separate transactions to Tornado Cash, totaling 1,100 ETH (equivalent to approximately $3.37 million). Despite being under sanctions by the US Department of the Treasury's OFAC, Tornado Cash remains a popular choice for cybercriminals to conceal their transaction activities. The hacker still has holdings of over $180 million in assets spread across various cryptocurrencies such as Ether, TRX, Bitcoin, BTCT, and Floki.
