[ZachXBT: A hacker laundered approximately $5.5 million after withdrawing 3,200 ETH via Circle's CCTP cross-chain protocol] According to a report by Jinse Finance, blockchain investigator ZachXBT disclosed on his personal channel that a hacker withdrew approximately 3,200 ETH via Tornado Cash between July 2 and July 3. The funds were linked to two private key leakage incidents. The address then used Circle's CCTP cross-chain bridge to launder approximately $5.5 million in assets across chains, subsequently transferring USDC into seven deposit addresses on the Arbitrum network. ZachXBT pointed out that the flow of funds exhibited a typical decentralized money laundering pattern, utilizing mixing tools and cross-chain infrastructure to reduce traceability. Currently, the related on-chain assets are still in continuous circulation.
