CoinMeta data: According to monitoring by the blockchain security firm Salus, attackers of triple-a transferred 4,970 ETH (valued at approximately $12.4 million) to the coin mixing protocol Tornado Cash on October 9th. This hacker had previously breached triple-a's own treasury in July this year, resulting in the theft of assets estimated at around $11.8 million. After transferring the stolen assets to the Ethereum mainnet and completing the asset exchange, the hacker dispersed the funds to two relay addresses on September 6th, and finally aggregated them into a single wallet on October 9th. The funds were then laundered in batches through 49 transactions of 100 ETH each and 7 transactions of 10 ETH each, into Tornado Cash.
