The Mixin hacker has resurfaced after two years of dormancy, now making efforts to launder parts of the 59,000 Ethereum stolen from the exploit.
The Mixin network exploiter, who drained about $200 million worth of Ethereum (ETH), Bitcoin (BTC), and other crypto assets from the Hong Kong-based network, appears to have begun laundering the ETH assets, recently transferring 2,005 ETH tokens to Tornado Cash.
Interestingly, the latest transaction originated from the original exploiter address after two years of dormancy and has reduced its Ethereum stash to 57,802 tokens worth $113.58 million at press time. The recent transactions were indexed by Lookonchain, a leading blockchain surveillance platform, today. On-chain data confirms that the asset movements began yesterday at 09:22 PM UTC, involving the transfer of exactly 2,005 ETH worth $3.996 million to an unidentified wallet, 0x9…87f. Interestingly, the wallet is relatively new, with the 2,005 ETH transfer being its first transaction. Barely a minute after receiving the tokens, 0x9…87f started moving the tokens to Tornado Cash in batches of 100 ETH transactions each. The address made 20 of these transfers to Tornado Cash, totaling 2,000 ETH. Currently, it has retained 5 ETH tokens.
Meanwhile, Lookonchain found that, shortly after the transfers to Tornado Cash, three new wallets purportedly connected to the Mixin hacker emerged and received a total of 2,087 ETH tokens from Tornado Cash across multiple transactions of about 99 ETH each. The wallets sold all the tokens for $4 million in DAI. At press time, the Mixin network hacker still holds 57,802 ETH tokens worth $133.58 million. Meanwhile, the Bitcoin address recorded no new movements during this time, remaining dormant since receiving 891 BTC during the September 2023 exploit.
