A wallet associated with the roughly $200 million hack of Mixin Network in September 2023 has resumed activity after nearly two years and moved thousands of ether through Tornado Cash.
Blockchain analytics account Lookonchain said the address sent 2,005 ETH, worth about $3.85 million, to the privacy mixer roughly 15 hours ago. Shortly afterward, three newly created wallets received a combined 2,087 ETH, valued at about $4.03 million, from Tornado Cash and sold the tokens at around $1,933 per ETH, per an X post.
The wallet still holds 57,849 ETH, worth roughly $113.4 million, and 891 BTC, valued at about $59.7 million at current prices, based on publicly visible blockchain data on Arkham.
Nearly three years ago, Mixin Network disclosed that its cloud service provider’s database had been attacked, resulting in the loss of approximately $200 million in assets. The haul included 59,854 ETH, 891 BTC, and roughly $23.57 million in USDT, which was later swapped for DAI.
Onchain attackers often leave funds untouched for months or years before attempting to launder them through mixers or other obfuscation tools.
Deposit and withdrawal services were temporarily suspended following the breach, and Mixin said it had contacted Google and blockchain security firm SlowMist to assist in the investigation. Mixin’s leadership also offered a $20 million bounty to the hacker in an onchain message. The incident drew scrutiny over the project’s infrastructure, with some users questioning the degree of decentralization after the exploit.
Mixin’s case adds to a growing ledger of large-scale crypto breaches. According to blockchain analytics firm Chainalysis, more than $3.4 billion worth of cryptocurrency was stolen in 2025, driven in part by a record $1.5 billion compromise at Bybit and a broader rise in attacks on centralized services and individual wallets.
