ZachXBT: A hacker withdrew 3200 ETH from Tornado and laundered about 5.5 million dollars through Circle's CCTP cross-chain

On-chain detective ZachXBT disclosed on his personal channel that a hacker extracted approximately 3,200 ETH through Tornado Cash between July 2 and 3. The funds are related to two private key leakage incidents. The address subsequently used Circle's CCTP cross-chain bridge to launder approximately $5,500,000 in assets across chains and further transferred USDC to seven deposit addresses on the Arbitrum network.

ZachXBT pointed out that the flow of funds exhibits a typical decentralized money laundering path, utilizing mixing tools and cross-chain infrastructure to reduce tracking difficulty. Currently, the related on-chain assets are still in circulation.
